    family of maize

    Based on a literature search, a total of 919 maize flowering time candidate genes (Data S7), including cloned genes and homologs of other plants, were preliminarily selected to conduct enrichment analyses (Danilevskaya et al., 2008; Chen et al., 2012; Dong et al., 2012; Hung et al., 2012). [76], As maize was introduced to new cultures, new uses were developed and new varieties selected to better serve in those preparations. This process makes use of the whole plant rather than simply using the kernels as in the production of fuel ethanol. [115] Because starch utilization in fermentation for ethanol production leaves other grain constituents more concentrated in the residue, the feed value per kg of DDGS, with regard to ruminant-metabolizable energy and protein, exceeds that of the grain. Sometimes a third crop, winter wheat, is added to the rotation. Maize and cornmeal (ground dried maize) constitute a staple food in many regions of the world. 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. B73)" Plants 9, no. They feature a large hopper that feeds the uniformly sized maize kernels (or wood pellets or cherry pits) into the fire. By the 1930s, companies such as Pioneer devoted to production of hybrid maize had begun to influence long-term development. Aux/IAA genes expand in the maize genome partly due to tandem and segmental duplication events. United States Department of Agriculture, Economic Research Service. Maize (Zea mays) is a plant of enormous modern-day economic importance as foodstuff and alternative energy source.Scholars agree that maize was domesticated from the plant teosinte (Zea mays spp. Massange-Sánchez, J.A. [citation needed], Maize has suboptimal amounts of the essential amino acids tryptophan and lysine, which accounts for its lower status as a protein source. 1841; 1851; 1861; 1871; 1881; 1891; 1901; 1911 Heuzé V., Tran G., Edouard N., Lebas F., 2017. In more arid lands, this was altered and seeds were planted in the bottom of 10–12 cm (4–4 1⁄2 in) deep furrows to collect water. Read and compare 300 reviews, choose your Family-Friendly Hotels in Maize, KS and save with Expedia.co.uk. Since then, even earlier dates have been published. F raw green soybeans A later technique was "checked maize", where hills were placed 1 m (40 in) apart in each direction, allowing cultivators to run through the field in two directions. [citation needed], The maize plant is often 3 m (10 ft) in height,[34] though some natural strains can grow 13 m (43 ft). There are about 1000 chromosomal aberrations (e.g., translocations and inversions) and stocks with abnormal chromosome numbers (e.g., tetraploids). [citation needed], In prehistoric times Mesoamerican women used a metate to process maize into ground cornmeal, allowing the preparation of foods that were more calorie dense than popcorn. D raw potato with flesh and skin Weeds are controlled through the use of herbicides, and no cultivation tillage is done during the growing season. Maize used for silage is harvested while the plant is green and the fruit immature. The process is thought by some to have started 7,500 to 12,000 years ago. [112], Stigmas from female maize flowers, popularly called corn silk, are sold as herbal supplements. UniProtKB. [63], Genetically modified (GM) maize was one of the 26 GM crops grown commercially in 2016. [52] The p1 gene encodes an Myb-homologous transcriptional activator of genes required for biosynthesis of red phlobaphene pigments, while the P1-wr allele specifies colorless kernel pericarp and red cobs, and unstable factor for orange1 (Ufo1) modifies P1-wr expression to confer pigmentation in kernel pericarp, as well as vegetative tissues, which normally do not accumulate significant amounts of phlobaphene pigments. A middle-aged couple and their three children were found dead on Saturday morning inside their house. [101] Before the advent of widespread ensilaging, it was traditional to gather the corn into shocks after harvesting, where it dried further. A small farmer might grow several different types of maize. Maize is still an important model organism for genetics and developmental biology today. Here the maize is harvested, shredded then placed in silage clamps from which it is fed into the biogas plants. [86], In most regions today, maize grown in residential gardens is still often planted manually with a hoe, whereas maize grown commercially is no longer planted manually but rather is planted with a planter. [115], Note: All nutrient values including protein and fiber are in %DV per 100 grams of the food item. Fernandez-Armesto, Felipe (2011). Species: Z. mays. Young ears can be consumed raw, with the cob and silk, but as the plant matures (usually during the summer months), the cob becomes tougher and the silk dries to inedibility. In 1840 there were 14 Maize families living in Pennsylvania. Multiple requests from the same IP address are counted as one view. [27][28] In the United States,[27] Canada,[29] Australia, and New Zealand,[30] corn primarily means maize; this usage started as a shortening of "Indian corn". Q = Quality of Protein in terms of completeness without adjusting for digestability.[119]. This protein has been linked to a rare and understudied allergy to maize in humans. [80], During the first millennium AD, maize cultivation spread more widely in the areas north. B73). [34] The leaves arise from the nodes, alternately on opposite sides on the stalk. After ceramic vessels were invented the Olmec people began to cook maize together with beans, improving the nutritional value of the staple meal. Corn is used as livestock feed, as human food, as biofuel, and as raw material in industry. Hyperosmolality-gated calcium-permeable channels (OSCA) have been characterized as osmosensors in Arabidopsis. By hand or mechanical picker, the entire ear is harvested, which then requires a separate operation of a maize sheller to remove the kernels from the ear. The teosinte origin theory was proposed by the Russian botanist Nikolai Ivanovich Vavilov in 1931 and the later American Nobel Prize-winner George Beadle in 1932. Maize is an annual grass in the family Gramineae, which includes such plants as wheat, rye, barley, rice, sorghum, and sugarcane. The structure of one R gene, Lc, was determined by sequencing cDNA and genomic clones. Today ensilaging can occur not only in siloes but also in silage wrappers. "The Phosphoglycerate Kinase (PGK) Gene Family of Maize (Zea mays var. The cob is close to a multiple fruit in structure, except that the individual fruits (the kernels) never fuse into a single mass. evolutionary history of maize R2R3-MYB gene family. Pennsylvania had the highest population of Maize families in 1840. James L. Reid was one of the earliest and most successful developing Reid's Yellow Dent in the 1860s. [citation needed], Coarse maize meal is made into a thick porridge in many cultures: from the polenta of Italy, the angu of Brazil, the mămăligă of Romania, to cornmeal mush in the US (or hominy grits in the South) or the food called mieliepap in South Africa and sadza, nshima, ugali and other names in other parts of Africa. Maize is relatively cheap and home-heating furnaces have been developed which use maize kernels as a fuel. According to OXFAM UK, after NAFTA went into effect, the price of maize in Mexico fell 70% between 1994 and 2001. A large corpus of data indicates that it [maize] was dispersed into lower Central America by 7600 BP [5600 BC] and had moved into the inter-Andean valleys of Colombia between 7000 and 6000 BP [5000–4000 BC]. "The globalization of hybrid maize, 1921–70. [88], In 2016, maize production was forecast to be over 15 billion bushels, an increase of 11% over 2014 American production. The pericarp of the fruit is fused with the seed coat referred to as "caryopsis", typical of the grasses, and the entire kernel is often referred to as the "seed". There are two major species of the genus Zea (out of six total): Zea mays (maize) and Zea diploperennis, which is a perennial type of teosinte. 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 and store it in bins. They are thick, partially photosynthetic and often deeply pigmented. [citation needed], "Feed maize" is being used increasingly for heating;[104] specialized corn stoves (similar to wood stoves) are available and use either feed maize or wood pellets to generate heat. The stems superficially resemble bamboo canes and the joints - DFY5B7 from Alamy's library of millions of high resolution stock photos, illustrations and vectors. Thomas E. Emerson, Kristin M. Hedman and Mary L. Simon. See further details. Maize meal is also a significant ingredient of some commercial animal food products. Formation: Millikin University (en) Activités: Acteur. Maize was the staple food, or a major staple – along with squash, Andean region potato, quinoa, beans, and amaranth – of most pre-Columbian North American, Mesoamerican, South American, and Caribbean cultures. For this purpose, variegated and colored leaf forms as well as those with colorful ears are used. 1100 BC. In the present study, we performed a comprehensive … The annual teosinte variety called Zea mays mexicana is the closest botanical relative to maize. Family tradition states that the Meysey family was from Brittany and that they accompanied William the Conqueror in his conquest of England at the Battle of Hastings in 1066 A.D. Maize is also used in making ethanol and other biofuels. [90] Maize is especially popular in Midwestern states such as Indiana and Illinois; in the latter, it was named the state's official grain in 2017.[91]. Teosinte bears little resemblance to the corn eaten today: Its cobs are tiny and its few kernels are protected by a nearly impenetrable outer casing. [63] There is conflicting evidence to support the hypothesis that maize yield potential has increased over the past few decades. Insect-resistant maize was grown in Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Egypt, the European Union, Honduras, Japan, Korea, Malaysia, Mexico, New Zealand, Philippines, South Africa, Switzerland, Taiwan, the United States, and Uruguay. (The term "teosinte" describes all. The Mesoamerican civilization, in particular, was deeply interrelated with maize. Because of the relationship between fuel and maize, prices paid for the crop now tend to track the price of oil. To date, no genome-wide characterization of this gene family has been conducted in maize (Zea mays). Bundles of dried maize stalks are often displayed along with pumpkins, gourds and straw in autumnal displays outside homes and businesses. 2020. National agricultural and industry associations often include the word maize in their name even in English-speaking countries where the local, informal word is something other than maize; for example, the Maize Association of Australia, the Indian Maize Development Association, the Kenya Maize Consortium and Maize Breeders Network, the National Maize Association of Nigeria, the Zimbabwe Seed Maize Association. For small farms, their unit cost can be too high, as their higher fixed cost cannot be amortized over as many units. Tracks of prehistoric man and ways of contact in the Americas according to cultivated plants. [126], In the United States, maize ears along with tobacco leaves are carved into the capitals of columns in the United States Capitol building. [citation needed], Maize has been an essential crop in the Andes since the pre-Columbian era. [33], Maize is preferred in formal, scientific, and international usage because it refers specifically to this one grain, unlike corn, which has a complex variety of meanings that vary by context and geographic region. What is the difference? - eXtension", "It's Time to Rethink America's Corn System", International Grains Council (international organization), "International Grains Council Market Report 28 November 2013", Genetically modified plants: Global Cultivation Area Maize, "A single domestication for maize shown by multilocus microsatellite genotyping", "Earliest Directional Evolution for Microsatellite Size in Maize", "Late ninth millennium B.P. The rapid growth of a field of maize allows a maze to be laid out using GPS at the start of a growing season and for the maize to grow tall enough to obstruct a visitor's line of sight by the start of the summer.
