74-488: The Sauk nation occupied this site as their principal village, called "Saukenuk". It was a well-drained area, suitable for growing corn . The Sauk had arrived by 1750, probably after the Fox Wars (1712-1733). When the explorer Jonathan Carver reached Saukenuk in 1766, he called it "the largest and best built Indian town" he had ever seen, "more like a civilized town than the abode of savages." The Sauk successfully farmed

148-508: A bronze bust fashioned from a plaster life mask. The Singing Bird Nature Center offers educational programs in the northwest section of the park. One section of the building is dedicated to the study of local native birds. The nature center is named after Black Hawk's wife Asshewaqua meaning Singing Bird. Maize Maize / m eɪ z / ( Zea mays ), also known as corn in North American English ,

222-811: A trumpet interchange , which then turns south. The concurrency then meets US 150 in Bloomington before I-55 branches southwestward at the I-55 Business (I-55 Bus.) interchange. After that, US 51 branches southward at US 51 Bus. I-74 then travels southeastward at this point. Along the way, it meets two local roads serving Downs and Le Roy , respectively; US 136 ; IL 54 ; another local road near Mansfield ; IL 47 ; and another local road near Mahomet . As it approaches Champaign, it then comes across I-57 , then Prospect Avenue, and then Neil Street. For Urbana , it serves Lincoln Avenue, US 45 , and IL 130 . After leaving

296-814: A conventional breeding program to provide optimized strains. The program began in the 1980s. Hybrid seeds are distributed in Africa by its Drought Tolerant Maize for Africa project. Tropical landraces remain an important and underused source of resistance alleles – both those for disease and for herbivores . Such alleles can then be introgressed into productive varieties. Rare alleles for this purpose were discovered by Dao and Sood, both in 2014. In 2018, Zerka Rashid of CIMMYT used its association mapping panel, developed for tropical drought tolerance traits. to find new genomic regions providing sorghum downy mildew resistance , and to further characterize known differentially methylated regions . Genetically modified maize

370-403: A corn head (with points and snap rolls instead of a reel) does not cut the stalk; it simply pulls the stalk down. The stalk continues downward and is crumpled into a mangled pile on the ground, where it usually is left to become organic matter for the soil . The ear of maize is too large to pass between slots in a plate as the snap rolls pull the stalk away, leaving only the ear and husk to enter

444-643: A hundred years. The spread of American settlers into Illinois and up the Mississippi River doomed the village. In multiple treaties, many of the Sauk had signed land cessions that sold the land under Saukenuk to the new American nation. Part of the tribe established new villages in Iowa and in Missouri nearer their winter hunting grounds. The campaign of 1832 led to a complete victory for the U.S. Army and

518-408: A large cob. Yellow maizes derive their color from carotenoids ; red maizes are colored by anthocyanins and phlobaphenes ; and orange and green varieties may contain combinations of these pigments. Maize has short-day photoperiodism , meaning that it requires nights of a certain length to flower. Flowering further requires enough warm days above 10 °C (50 °F). The control of flowering

592-499: A measure of protection against a wide range of pests. Because of its shallow roots, maize is susceptible to droughts, intolerant of nutrient-deficient soils, and prone to being uprooted by severe winds. Maize is diploid with 20 chromosomes . 83% of allelic variation within the genome derives from its teosinte ancestors, primarily due to the freedom of Zea species to outcross . Barbara McClintock used maize to validate her transposon theory of "jumping genes", for which she won

666-638: A place but a condition, a savage rather than a civilized grain". International groups such as the Centre for Agriculture and Bioscience International consider maize the preferred common name. The word maize is used by the UN's Food and Agriculture Organization , and in the names of the International Maize and Wheat Improvement Center of Mexico, the Indian Institute of Maize Research,

740-601: A plant that uses C 4 carbon fixation , maize is a considerably more water-efficient crop than plants that use C 3 carbon fixation such as alfalfa and soybeans . Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for pollination. In the United States, a good harvest was traditionally predicted if the maize was "knee-high by the Fourth of July ", although modern hybrids generally exceed this growth rate. Maize used for silage

814-545: A short distance. Southeast of Colona , I-280 ends at the Big X interchange while I-74 turns southward via ramps. This interchange is also where I-80 turns east via ramps. At this point, I-74 runs along IL 110 all the way to Galesburg . Along the way, the freeway comes across IL 81 and IL 17 before meeting US 34 . At this point, IL 110 travels west along US 34 while I-74 continues south. East of Galesburg, I-74 begins to curve southeastward. Along

888-670: Is a major pest of maize in Asia. Interstate 74 (Illinois) Interstate 74 ( I-74 ) in the US state of Illinois is a major northwest–southeast Interstate Highway that runs across the central portion of the state. It runs from the Iowa state line at the Mississippi River near the city of Rock Island and runs southeast to the Indiana state line east of Danville , a distance of 220.34 miles (354.60 km). The highway runs through

962-426: Is a problem in Asia. Some fungal diseases of maize produce potentially dangerous mycotoxins such as aflatoxin . In the United States, major diseases include tar spot , bacterial leaf streak , gray leaf spot , northern corn leaf blight, and Goss's wilt ; in 2022, the most damaging disease was tar spot, which caused losses of 116.8 million bushels . Maize sustains a billion dollars' worth of losses annually in

1036-674: Is a tall stout grass that produces cereal grain . It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte . Native Americans planted it alongside beans and squashes in the Three Sisters polyculture . The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen , and female inflorescences called ears . The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize relies on humans for its propagation. Since

1110-408: Is composed of transposons , contains 32,540 genes. Much of it has been duplicated and reshuffled by helitrons , a group of transposable elements within maize's DNA. Maize breeding in prehistory resulted in large plants producing large ears. Modern breeding began with individuals who selected highly productive varieties in their fields and then sold seed to other farmers. James L. Reid was one of

1184-489: Is cultivated throughout the world; a greater weight of maize is produced each year than any other grain. In 2020, world production was 1.1 billion tonnes. It is afflicted by many pests and diseases ; two major insect pests, European corn borer and corn rootworms , have each caused annual losses of a billion dollars in the US. Modern plant breeding has greatly increased output and qualities such as nutrition, drought tolerance, and tolerance of pests and diseases. Much maize

1258-414: Is harvested while the plant is green and the fruit immature. Sweet corn is harvested in the "milk stage", after pollination but before starch has formed, between late summer and early to mid-autumn. Field maize is left in the field until very late in the autumn to thoroughly dry the grain, and may, in fact, sometimes not be harvested until winter or even early spring. The importance of sufficient soil moisture

1332-512: Is located in a lodge constructed in 1934 by the Civilian Conservation Corps and was named after John Hauberg, a philanthropist from Rock Island . Exhibits include full-size replicas of Sauk winter and summer houses, dioramas depicting Native life typical of the period from 1750 to 1830, trade goods, jewelry and domestic items, and several Black Hawk artifacts, including his tomahawk , two of his clay tobacco pipes , and

1406-533: Is now genetically modified . As a food, maize is used to make a wide variety of dishes including Mexican tortillas and tamales , Italian polenta , and American hominy grits . Maize protein is low in some essential amino acids , and the niacin it contains only becomes available if freed by alkali treatment . In Mesoamerica, maize is deified as a maize god and depicted in sculptures. Maize requires human intervention for it to propagate. The kernels of its naturally-propagating teosinte ancestor fall off

1480-468: Is set genetically; the physiological mechanism involves the phytochrome system. Tropical cultivars can be problematic if grown in higher latitudes, as the longer days can make the plants grow tall instead of setting seed before winter comes. On the other hand, growing tall rapidly could be convenient for producing biofuel. Immature maize shoots accumulate a powerful antibiotic substance, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one ( DIMBOA ), which provides

1554-498: Is shown in many parts of Africa, where periodic drought regularly causes maize crop failure and consequent famine . Although it is grown mainly in wet, hot climates, it can thrive in cold, hot, dry or wet conditions, meaning that it is an extremely versatile crop. Maize was planted by the Native Americans in small hills of soil, in the polyculture system called the Three Sisters . Maize provided support for beans ;

1628-557: Is the domesticated variant of the four species of teosintes , which are its crop wild relatives . The teosinte origin theory was proposed by the Russian botanist Nikolai Ivanovich Vavilov in 1931, and the American Nobel Prize -winner George Beadle in 1932. The two plants have dissimilar appearance, maize having a single tall stalk with multiple leaves and teosinte being a short, bushy plant. The difference between

1702-405: Is the leaf most closely associated with a particular developing ear. This leaf and those above it contribute over three quarters of the carbohydrate ( starch ) that fills the grain. The grains are usually yellow or white in modern varieties; other varieties have orange, red, brown, blue , purple , or black grains. They are arranged in 8 to 32 rows around the cob; there can be up to 1200 grains on

1776-612: The Balsas River valley in Mexico's southwestern highlands, as the crop wild relative genetically most similar to modern maize. The middle part of the short Balsas River valley is the likely location of early domestication. Stone milling tools with maize residue have been found in an 8,700 year old layer of deposits in a cave not far from Iguala, Guerrero . Doebley and colleagues showed in 2002 that maize had been domesticated only once, about 9,000 years ago, and then spread throughout

1850-705: The Columbian exchange , it has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat and rice . Much maize is used for animal feed , whether as grain or as the whole plant, which can either be baled or made into the more palatable silage . Sugar-rich varieties called sweet corn are grown for human consumption, while field corn varieties are used for animal feed, for uses such as cornmeal or masa , corn starch , corn syrup , pressing into corn oil , alcoholic beverages like bourbon whiskey , and as chemical feedstocks including ethanol and other biofuels . Maize

1924-607: The 1983 Nobel Prize in Physiology or Medicine . Maize remains an important model organism for genetics and developmental biology . The MADS-box motif is involved in the development of maize flowers. The Maize Genetics and Genomics Database is funded by the US Department of Agriculture to support maize research. The International Maize and Wheat Improvement Center maintains a large collection of maize accessions tested and cataloged for insect resistance. In 2005,

1998-662: The Americas. Maize pollen dated to 7,300 years ago from San Andres, Tabasco has been found on the Caribbean coast. A primitive corn was being grown in southern Mexico, Central America, and northern South America 7,000 years ago. Archaeological remains of early maize ears, found at Guila Naquitz Cave in the Oaxaca Valley , are roughly 6,250 years old; the oldest ears from caves near Tehuacan , Puebla, are 5,450 years old. Around 4,500 years ago, maize began to spread to

2072-479: The B-vitamin niacin , the lack of which caused pellagra . Once alkali processing and dietary variety were understood and applied, pellagra disappeared in the developed world. The development of high- lysine maize and the promotion of a more balanced diet have contributed to its demise. Pellagra still exists in food-poor areas and refugee camps where people survive on donated maize. The name maize derives from

2146-716: The Indiana state line. In November 2006, major work was completed on the Upgrade 74 project for the portion of I-74 in the Midwest . This multiyear project, begun in April 2002, saw the complete renovation of I-74 through East Peoria and Peoria . Most notably, the Interstate was widened to three lanes through the cities, many blind or hairpin exits and entrances to the highway were removed or corrected, and many bridges crossing

2220-665: The Iowa state line and the Mississippi River via the I-74 Bridge ( through arch span), I-74, as well as US 6, enters the city of Moline . At first, the freeway travels southward, meeting River Drive, Illinois Route 92 (IL 92, 6th Avenue), 7th Avenue, Avenue of the Cities, and IL 5 (John Deere Road), before reaching I-280 . Near the Quad Cities International Airport , I-74 turns eastward along I-280 while US 6 continues south for

The island is now mainly a 180-foot-deep quarry with some residential development on the west side. The historic site is served by Illinois Route 5 , which intersects with Interstate 74 in nearby Moline, Illinois . The Hauberg Museum specializes in Sauk and Meskwaki cultural objects and artifacts. The museum

2516-586: The Spanish form maíz of the Taíno mahis . The Swedish botanist Carl Linnaeus used the common name maize as the species epithet in Zea mays . The name maize is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike corn , which has a complex variety of meanings that vary by context and geographic region. Most countries primarily use

2590-562: The US National Science Foundation , Department of Agriculture, and the Department of Energy formed a consortium to sequence the maize genome . The resulting DNA sequence data was deposited immediately into GenBank , a public repository for genome-sequence data. Sequencing of the maize genome was completed in 2008. In 2009, the consortium published results of its sequencing effort. The genome, 85% of which

Sauk hunters skinned their catches and sold the peltry to fur traders from the Great Lakes . From 1763 on, these traders were mostly British, and from the 1780s on, most of them were employees or contractors of the Canada-based North West Company . In the spring, the Sauk gathered in sugar camps for maple sugaring before returning to

2812-418: The beans provided nitrogen derived from nitrogen-fixing rhizobia bacteria which live on the roots of beans and other legumes ; and squashes provided ground cover to stop weeds and inhibit evaporation by providing shade over the soil. Sweet corn, harvested earlier than maize grown for grain, grows to maturity in a period of from 60 to 100 days according to variety. An extended sweet corn harvest, picked at

2886-613: The body of Christ. Maize spread to the rest of the world because of its ability to grow in diverse climates. It was cultivated in Spain just a few decades after Columbus's voyages and then spread to Italy, West Africa and elsewhere. By the 17th century, it was a common peasant food in Southern Europe. By the 18th century, it was the chief food of the southern French and Italian peasantry, especially as polenta in Italy. When maize

2960-529: The city of Urbana, it then serves two local roads for St. Joseph and Ogden , IL 49 , another local road for Oakwood , and US 150. At this point, I-74 becomes a freeway bypass of Danville. In Tilton , it serves G Street as well as US 150/ IL 1 . After crossing the Vermilion River , it then meets Bowman Road and Lynch Road. Shortly after the Lynch Road interchange, I-74 crosses

3034-577: The cob on their own, while those of domesticated maize do not. All maize arose from a single domestication in southern Mexico about 9,000 years ago. The oldest surviving maize types are those of the Mexican highlands. Maize spread from this region to the lowlands and over the Americas along two major paths. The centre of domestication was most likely the Balsas River valley of south-central Mexico. Maize reached highland Ecuador at least 8000 years ago. It reached lower Central America by 7600 years ago, and

3108-425: The earliest and most successful, developing Reid's Yellow Dent in the 1860s. These early efforts were based on mass selection (a row of plants is grown from seeds of one parent), and the choosing of plants after pollination (which means that only the female parents are known). Later breeding efforts included ear to row selection (C. G. Hopkins c. 1896), hybrids made from selected inbred lines (G. H. Shull, 1909), and

3182-413: The entire ear is harvested, which requires a separate operation of a maize sheller to remove the kernels from the ear. Whole ears of maize were often stored in corn cribs , sufficient for some livestock feeding uses. Today corn cribs with whole ears, and corn binders, are less common because most modern farms harvest the grain from the field with a combine harvester and store it in bins . The combine with

3256-774: The expansion of the Inca Empire , maize was traded and transported as far south as 40° S in Melinquina, Lácar Department , Argentina, probably brought across the Andes from Chile. After the arrival of Europeans in 1492, Spanish settlers consumed maize, and explorers and traders carried it back to Europe . Spanish settlers much preferred wheat bread to maize. Maize flour could not be substituted for wheat for communion bread, since in Christian belief at that time only wheat could undergo transubstantiation and be transformed into

3330-713: The freeway then meets IL 40 (Riverfront Drive), US 24 /US 150/IL 29 (where IL 29 leaves the concurrency)/ IL 116 , US 150/ IL 8 , and Pinecrest Drive, before meeting I-474 again. After the I-474 interchange, it then meets the I-155 interchange, as well as Morton Avenue, in Morton . The freeway then meets IL 117 in Goodfield , a local road near Carlock , and US 150 near Yuton . As it approaches Normal , I-74 then meets I-55 /US 51 at

3404-532: The highly successful double cross hybrids using four inbred lines ( D. F. Jones c. 1918, 1922). University-supported breeding programs were especially important in developing and introducing modern hybrids. Since the 1940s, the best strains of maize have been first-generation hybrids made from inbred strains that have been optimized for specific traits, such as yield, nutrition, drought, pest and disease tolerance. Both conventional cross-breeding and genetic engineering have succeeded in increasing output and reducing

3478-545: The highway were replaced. The biggest part of this project was to work on the Murray Baker Bridge , over which I-74 crosses the Illinois River . The bridge was completely closed to traffic while being partially demolished and reconstructed from April 2 to October 15, 2005. During this time, I-74 was disconnected between Peoria and East Peoria. In late March 2013, the biggest road reconstruction project in

3552-550: The history of the word corn in North America that "[t]o say the word corn is to plunge into the tragi-farcical mistranslations of language and history". Similar to the British usage, the Spanish referred to maize as panizo , a generic term for cereal grains, as did Italians with the term polenta . The British later referred to maize as Turkey wheat, Turkey corn, or Indian corn; Fussell comments that "they meant not

3626-419: The machinery. The combine separates the husk and the cob, keeping only the kernels. Drying is vital to prevent or at least reduce damage by mould fungi, which contaminate the grain with mycotoxins . Aspergillus and Fusarium spp. are the most common mycotoxin sources, and accordingly important in agriculture. If the moisture content of the harvested grain is too high, grain dryers are used to reduce

3700-593: The major cities of Champaign , Bloomington , Peoria , and Moline . The highway is officially named after Everett McKinley Dirksen , a Republican senator and representative from Pekin from 1933 to his death in 1969. I-74 in Illinois runs parallel with U.S. Route 6 (US 6) in the Quad Cities , US 150 from the Quad Cities to Danville, and US 136 east of Danville. After crossing

3774-413: The milk stage, can be arranged either by planting a selection of varieties which ripen earlier and later, or by planting different areas at fortnightly intervals. Maize harvested as a grain crop can be kept in the field a relatively long time, even months, after the crop is ready to harvest; it can be harvested and stored in the husk leaves if kept dry. Before World War II , most maize in North America

3848-427: The moisture content by blowing heated air through the grain. This can require large amounts of energy in the form of combustible gases ( propane or natural gas ) and electricity to power the blowers. Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2020, total world production was 1.16 billion tonnes , led by the United States with 31.0% of

3922-501: The need for cropland, pesticides, water and fertilizer. There is conflicting evidence to support the hypothesis that maize yield potential has increased over the past few decades. This suggests that changes in yield potential are associated with leaf angle, lodging resistance, tolerance of high plant density, disease/pest tolerance, and other agronomic traits rather than increase of yield potential per individual plant. Certain varieties of maize have been bred to produce many ears; these are

3996-400: The new crop. The rise in maize cultivation 500 to 1,000 years ago in what is now the southeastern United States corresponded with a decline of freshwater mussels , which are very sensitive to environmental changes. Because it is cold-intolerant, in the temperate zones maize must be planted in the spring. Its root system is generally shallow, so the plant is dependent on soil moisture. As

4070-465: The north. In the United States, maize was first cultivated at several sites in New Mexico and Arizona about 4,100 years ago. During the first millennium AD, maize cultivation spread more widely in the areas north. In particular, the large-scale adoption of maize agriculture and consumption in eastern North America took place about A.D. 900. Native Americans cleared large forest and grassland areas for

4144-462: The park in 1934–1942. The last couple of blocks on the southern portion of 11th street Rock Island ( U.S. Route 67 ) now cover the former site of the Sauk village of Saukenuk, with Black Hawk State Historic Site and John Hauberg Museum of Native American Life slightly to the east. Saukenuk had strong ties with the Meskwaki village to the north, what is now downtown Rock Island. Vandruff Island in

4218-760: The presence of Starlink genetically modified corn, which had been approved only for animal consumption. The maize genus Zea is relatively closely related to sorghum , both being in the PACMAD clade of Old World grasses, and much more distantly to rice and wheat , which are in the other major group of grasses, the BOP clade . It is closely related to Tripsacum , gamagrass. various grasses e.g. fescue , ryegrass Hordeum (barley) Triticum (wheat) Oryza (rice) Pennisetum (fountaingrasses) Sorghum (sorghum) Tripsacum (gamagrass) Zea mays (maize) other Zea species ( teosintes ) Maize

4292-491: The source of the " baby corn " used as a vegetable in Asian cuisine . A fast-flowering variety named mini-maize was developed to aid scientific research, as multiple generations can be obtained in a single year. One strain called olotón has evolved a symbiotic relationship with nitrogen-fixing microbes, which provides the plant with 29%–82% of its nitrogen. The International Maize and Wheat Improvement Center (CIMMYT) operates

4366-415: The stalk. Maize is monoecious , with separate male and female flowers on the same plant. At the top of the stem is the tassel, an inflorescence of male flowers; their anthers release pollen, which is dispersed by wind . Like other pollen, it is an allergen , but most of it falls within a few meters of the tassel and the risk is largely restricted to farm workers. The female inflorescence, some way down

4440-417: The state of Illinois. Many of Black Hawk's followers were killed and the Quad Cities region was completely opened to settlement. However, many white Americans admired Black Hawk's courage in defense of his band's ancestral lands, and the native leader was elevated to the rank of a folk hero . A statue of Black Hawk was raised on the site in 1892, and the Civilian Conservation Corps redeveloped and improved

4514-425: The stem from the tassel, is first seen as a silk, a bundle of soft tubular hairs , one for the carpel in each female flower, which develops into a kernel (often called a seed. Botanically, as in all grasses, it is a fruit, fused with the seed coat to form a caryopsis ) when it is pollinated. A whole female inflorescence develops into an ear or corncob , enveloped by multiple leafy layers or husks. The ear leaf

4588-608: The term maize , and the name corn is used mainly in the United States and a handful of other English-speaking countries. In countries that primarily use the term maize , the word corn may denote any cereal crop, varying geographically with the local staple , such as wheat in England and oats in Scotland or Ireland. The usage of corn for maize started as a shortening of " Indian corn " in 18th-century North America. The historian of food Betty Fussell writes in an article on

4662-472: The total (table). China produced 22.4% of the global total. Many pests can affect maize growth and development, including invertebrates, weeds, and pathogens. Maize is susceptible to a large number of fungal, bacterial, and viral plant diseases . Those of economic importance include diseases of the leaf, smuts such as corn smut , ear rots and stalk rots. Northern corn leaf blight damages maize throughout its range, whereas banded leaf and sheath blight

4736-475: The transfer of Illinois lands to the U.S. Government, including Saukenuk. The Sauk did not consider this treaty valid, and they continued to live at the village. When Thomas Forsyth arrived in Saukenuk in 1817, he described it as the most populous Indian village he had ever seen. By 1826, an estimated 4,800 Sauk lived in and around Saukenuk. Others who passed through, such as William H. Keating , noted that

4810-500: The two is largely controlled by differences in just two genes, called grassy tillers-1 ( gt1 , A0A317YEZ1 ) and teosinte branched-1 ( tb1 , Q93WI2 ). In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum , a related genus; this has been refuted by modern genetic testing . In 2004, John Doebley identified Balsas teosinte, Zea mays subsp. parviglumis , native to

4884-589: The valleys of the Colombian Andes between 7000 and 6000 years ago. The earliest maize plants grew a single, small ear per plant. The Olmec and Maya cultivated maize in numerous varieties throughout Mesoamerica ; they cooked, ground and processed it through nixtamalization . By 3000 years ago, maize was central to Olmec culture, including their calendar, language, and myths. The Mapuche people of south-central Chile cultivated maize along with quinoa and potatoes in pre-Hispanic times. Before

4958-438: The village (left empty since the fall) to plant crops and bury their dead. The Sauk developed military and economic ties with British North America . Due to these ties, the Sauk expected British military assistance. Some of the Sauk traveled every year to British forts on far-away Lake Superior and near Detroit for trading and gift-giving. A disputed 1804 St. Louis Treaty between Quashquame and William Henry Harrison led to

5032-459: The village was not limited to the Sauk. Keating estimated only about 20% of the warriors that the Sauk could muster had pure Sauk ancestry. It was the largest single settlement in the new U.S. state of Illinois . This is how Black Hawk described Saukenuk: Our village was situated on the north side of Rock river, at the foot of its rapids, and on the point of land between Rock river and the Mississippi. . . .
