chromosome number of soybean

chromosome number of soybean

Soy flour refers to soybeans ground finely enough to pass through a 100-mesh or smaller screen where special care was taken during desolventizing (not toasted) to minimize denaturation of the protein to retain a high protein dispersibility index, for uses such as food extrusion of textured vegetable protein. Soybeans were probably first cultivated in Canada by 1855, and definitely in 1895 at Ontario Agricultural College. To identify centromeric satellite repeats, we constructed a whole-genome shotgun (WGS) library of soybean, and generated 1,454 WGS sequences (GenBank CL867099–CL868434; Lin et al., 2005). chicken, hog, turkey) on a large industrial scale. Soybean seeds come in a wide variety of sizes and hull colors such as black, brown, yellow, and green. The early vigor phenotypic traits studied in G. soja are node count, inter-node length, early growth rate, and early plant height. Molecular and Chromosomal Evidence for Allopolyploidy in Soybean, The PPR-SMR Protein ATP4 Is Required for Editing the Chloroplast, The NAC Transcription Factors OsNAC20 and OsNAC26 Regulate Starch and Storage Protein Synthesis, Molecular Basis for Chemical Evolution of Flavones to Flavonols and Anthocyanins in Land Plants, by The American Society of Plant Biologists, http://www.phrap.org/phredphrapconsed.html, http://tree.bio.ed.ac.uk/software/figtree/, © 2009 American Society of Plant Biologists. [67][76] The cultivation of soybeans began in the eastern half of northern China by 2000 BC, but is almost certainly much older. However, this observation must be reconciled with the even longer-term maintenance of two repeat classes in the soybean genome. SOYBEAN GENETICS COMMITTEE REPORT Minutes of the Meeting The Soybean Genetics Committee met Feb. 25, 1985, at the Ramada Inn - Executive Plaza, Memphis, TN. This ability to fix nitrogen allows farmers to reduce nitrogen fertilizer use and increase yields when growing other crops in rotation with soy. "[156] A 2010 review showed that neither soy foods nor isoflavone supplements alter measures of bioavailable testosterone or estrogen concentrations in men. Copyright © 2021 by The American Society of Plant Biologists. BACs 161O23 and 38L01 labeled with biotin and detected with AF488 streptavidin (green channel, arrows) that cross hybridize to duplicated regions in two homologs (Walling et al., 2005) were used in conjunction with CentGm-1 (labeled with digoxigenin and detected with rhodamine anti-digoxigenin, red channel) and CentGm-2 (labeled and detected with both fluorophores to result in yellow). The rhg1-b allele of soybean is widely used for resistance against soybean cyst nematode (SCN), the most economically damaging pathogen of soybeans in the United States. [96] In 1931, Ford hired chemists Robert Boyer and Frank Calvert to produce artificial silk. One locus at chromosome 19 was shared by both IN and PH, suggesting these traits are controlled by genes that have pleotropic effects. [90], It was not until Lafayette Mendel and Thomas Burr Osborne showed that the nutritional value of soybean seeds could be increased by cooking, moisture or heat, that soy went from a farm animal feed to a human food. It is an important topic of review in basic plant breeding. One type of chromosome aberration, an inversion, results in the reverse orientation of genes on a chromosome. The review panel also found that soy isoflavones have not been shown to reduce post-menopausal "hot flashes" and the efficacy and safety of isoflavones to help prevent cancers of the breast, uterus or prostate is in question. Soy products also are used as a low-cost substitute in meat and poultry products. [6] The genus name is not related to the amino acid glycine. The terminal 2 to 3 mm of each root tip was then excised and individually transferred to microfuge tubes containing 20 μL of enzyme solution containing 1% Pectolyase Y-23 (MP Biomedicals) and 2% Onozuka R-10 cellulase (Research Products International) in citric buffer (10 mm sodium citrate, 10 mm sodium EDTA, pH 5.5) and digested for 55 min in a 37°C water bath. C, Sequence alignment of the two representative CentGm-2 and CentGm-1 repeats (shown with asterisks in section A). [180] Meta-analyses on the association between soy consumption and prostate cancer risk in men concluded that dietary soy may lower the risk of prostate cancer. AHA concluded that "many soy products should be beneficial to cardiovascular and overall health because of their high content of polyunsaturated fats, fiber, vitamins, and minerals and low content of saturated fat". The first stage of growth is germination, a method which first becomes apparent as a seed's radicle emerges. Soybean seed contains 18–19% oil. [67] From about the first century AD to the Age of Discovery (15–16th centuries), soybeans were introduced into across South and Southeast Asia. 107:745-750 and citations therein]. 2B). [50], Soil scientists Edson Lobato (Brazil), Andrew McClung (U.S.), and Alysson Paolinelli (Brazil) were awarded the 2006 World Food Prize for transforming the ecologically biodiverse savannah of the Cerrado region of Brazil into highly productive cropland that could grow profitable soybeans. A combined FISH experiment with both repeats revealed that the two repeats mark 18 nonoverlapping sets of chromosomes at the centromeric regions (Fig. [177], Although considerable research has examined the potential for soy consumption to lower the risk of breast cancer in women, there is insufficient population evidence to make a conclusion about this relationship, as of 2016. Lafayette, California: Soyinfo Center. We performed computational analyses on five shotgun sequencing clones that contained CentGm sequences on both ends of the clone (three clones with CentGm-1 and two with CentGm-2 on both ends) to determine the level of monomer variation within defined regions (regions the size of a shotgun clone, approximately 4 kb). The Protein Digestibility Corrected Amino Acid Score (PDCAAS) of soy protein is the nutritional equivalent of meat, eggs, and casein for human growth and health. The results indicated that each pair of homologs is indeed marked by a different centromeric repeat (Fig. Heuzé V., Tran G., Nozière P., Lessire M., Lebas F., 2017. In 1879, the first domesticated soybeans arrived in Australia, a gift of the Minister of the Interior Department, Japan. (462 references; 20 photos and illustrations. The divergence of these now-extinct x progenitors occurred about twice as long ago as the divergence between the soybean lineage and the lineage of perennial Glycine species. Trihelix transcription factors play multiple roles in plant growth, development and various stress responses. NCDEX: National Commodity and Derivatives Exchange, India. Soybeans are also used in industrial products, including oils, soap, cosmetics, resins, plastics, inks, crayons, solvents, and clothing. [46] Soya imports represent 47% of Europe’s deforestation footprint, compared to 14% for pasture expansion for livestock and 10% for palm oil. [67] The first unambiguously domesticated, cultigen-sized soybean was discovered in Korea at the Mumun-period Daundong site. Soybean protein isolate has a biological value of 74, whole soybeans 96, soybean milk 91, and eggs 97. Lafayette, California; Soyinfo Center. High-fat soy flour can also be produced by adding back soybean oil to defatted flour, usually at the level of 15%. Lafayette, California. [54], Soybeans are one of the "biotech food" crops that have been genetically modified, and genetically modified soybeans are being used in an increasing number of products. FigTree version1.2.2 (http://tree.bio.ed.ac.uk/software/figtree/) was used to draw and view the unrooted neighbor-joining tree. In rice and Arabidopsis, both of which are believed to be paleoployploids or extensive paleo-aneuploids (Vision et al., 2000; Vandepoele et al., 2003), only single families of centromeric satellite repeats, e.g. Soybeans grown in sewage sludge likely contain elevated concentrations of metals. It is most likely that the centromeric repeats are arranged in the same patterns in G. soja as in soybean, as seen in 92/91-bp ladders on Southern blots (CentGm-1 shown in Fig. 1, A–D ). One scenario is seen in very young infants who have vomiting and diarrhoea when fed soy-based formula, which resolves when the formula is withdrawn. However, the genetic variations underlying soybean domestication are not well known. This review by the Genetics Committee will serve to insure orderly identification and use of genetic nomenclature and to avoid conflict of symbols. Undigested oligosaccharides are broken down in the intestine by native microbes, producing gases such as carbon dioxide, hydrogen, and methane. A Comprehensive Survey of International Soybean Research - Genetics, Physiology, Agronomy and Nitrogen Relationships . The author responsible for distribution of materials integral to the findings presented in this article in accordance with the policy described in the Instructions for Authors (www.plantphysiol.org) is: Scott A. Jackson (sjackson{at}purdue.edu). Ford also informed in public relation releases that in 1935 over five million acres (20,000 km2) was dedicated to growing soybeans in the United States. Plants 2020, 9, 937 3 of 14 Table 1. This striking genomic feature of soybean is attributed to WGDs approximately 13 and 59 million years ago ( Schmutz et al. The genetic map contained 8078 SLAF markers distributing across 20 soybean chromosomes with a total genetic distance of 3780.98 cM and an average genetic distance of 0.59 cM between adjacent markers. [110], The soybean first arrived in South America in Argentina in 1882. Starting in February 1876, he published these results first in various journal articles, and finally in his magnum opus, Die Sojabohne (The Soybean) in 1878. These substitutes are readily available in most supermarkets. [128] Spring grasses are rich in omega-3 fatty acids, whereas soy is predominantly omega-6. Free online. (a, b) Significant QTNs determined using (a) a single trait genome-wide association study (GWAS) and (b) a multi-trait GWAS. The origin of soy bean cultivation remains scientifically debated. The membrane was prehybridized for at least 30 min in Church hybridization buffer (1% bovine serum albumin/1 mm EDTA/7% SDS/0.5 m sodium phosphate) at 58°C. Soybeans are a significant source of mammalian lignan precursor secoisolariciresinol containing 13–273 µg/100 g dry weight. The regeneration ability of soybean directly affects the application of biotechnology. Raw soybeans are 20% fat, including saturated fat (3%), monounsaturated fat (4%) and polyunsaturated fat, mainly as linoleic acid (table). The absence of hybridization to CentGm-1 and CentGm-2 in the other relatives suggests the rapid divergence of centromeric satellite repeats within Glycine, as seen in Oryza (Lee et al., 2005). [54][55], Human sewage sludge can be used as fertilizer to grow soybeans. [47][48], A moratorium introduced by Brazilian soy exporters in 2006 reduced expansion of soy into the Amazon, but did not protect other ecosystems, such as the neighboring Cerrado, where soy expansion still brings deforestation. Shurtleff, W.; Aoyagi, A.; 2015. [91][92], William Morse is considered the "father" of modern soybean agriculture in America. [citation needed] Additionally soybeans are a rich source of sphingolipids.[39]. The 464 sequences were aligned using ClustalX (Thompson et al., 1994) using default options. all twenty chromosomes [8,9]. For example, soybean products, such as textured vegetable protein (TVP), are ingredients in many meat and dairy substitutes. Wash solution was removed and chromosome spreads were covered with 10 μL of 4′,6-diamino-2-phenilinodole (DAPI) in Vectashield mounting medium (Vector Laboratories) and a glass coverslip. B, DAPI-stained chromosomes. It remains only a minor crop there, but its uses for human food are growing steadily. The number of pods per plant varies drastically with the number of plants per acre and plant to plant spacing. Soybean hulls. Biotin-labeled probes were detected using a single layer of AF488 streptavidin, and the digoxigenin-labeled probes were detected using a single layer of sheep anti-digoxigenin conjugated with rhodamine (Roche). There is insufficient research to indicate whether taking soy dietary supplements has any effect on health or cancer risk. DOI: https://doi.org/10.1104/pp.109.137935. [15] This is the first stage of root growth and occurs within the first 48 hours under ideal growing conditions. Therefore, we searched the repeat database that we obtained from the WGS sequences using a tandem repeat finding program (Benson, 1999), and identified another subfamily of high-copy satellite repeats similar in structure to CentGm-1. CentO in rice (Dong et al., 1998) and pAL1 in Arabidopsis (Kamm et al., 1995), were found in respective genomes. [88] Although soybean was introduced into North America in 1765, for the next 155 years, the crop was grown primarily for forage. These criteria were chosen so as to retain potentially diverged sequences. The first photosynthetic structures, the cotyledons, develop from the hypocotyl, the first plant structure to emerge from the soil. [167] It is very difficult to give a reliable estimate of the true prevalence of soy allergy in the general population. The Soybean Genetics Corrmittee requests that researchers submit all manu-scripts concerning qualitative genetic interpretation and symbols to the Corrmittee Chairman. [85][86][87] Bowen grew soy near Savannah, Georgia, possibly using funds from Flint, and made soy sauce for sale to England. However, the unequal number of homologous centromere classes could also be attributable to random segregational loss of parental chromosomes during a period of tetrasomic chromosome association in a genetic autopolyploid, or the newly formed polyploid Glycine could have been a segmental allopolyploid, with attributes of both auto- and allopolyploidy at different loci. Although CentGm-1 and CentGm-2 are specific to mostly nonoverlapping sets of chromosomes, we asked whether the two centromeric repeats would differentially target the previously identified homologs. Rhizobium japonicum; Jordan 1982). This indicates that there has been little recombination and homogenization of satellite DNA between these two sets of centromeres. "History of Soybeans and Soyfoods in Austria and Switzerland (1781–2015)." The faint band seen in Glycine pescadrensis (Fig. These two subfamilies of satellite repeats mark distinct subsets of soybean centromeres and, in at least one case, a pair of homologs, suggesting their origins from an allopolyploid event. Phylogenetic analysis can identify a pattern consistent with allopolyploidy, in which each homolog is most closely related to a different progenitor ortholog. However, it is also self-limiting and will often disappear in the toddler years. Posthybridization formamide treatments and stringency washes were the same. To identify the soybean genes responsive to HrpG, two chromosome segment substitution lines (CSSLs) carrying the wild soybean genome, but with opposite phenotypes following Xanthomonas inoculations, were used to analyze gene expression networks based on RNA sequencing at three time points after inoculations with wild-type Xanthomonas or the hrpG deletion mutant. Soy did not fare well in the low latitudes. The SSR alleles present at three (AT) n /(TA) n and four (ATT) n /(TAA) n loci were determined in each of 96 diverse soybean genotypes. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) This parallels the observation that no WGS clones screened in this study contained both CentGm-1 and CentGm-2 sequences. [170], Soybeans contain isoflavones called genistein and daidzein, which are one source of phytoestrogens in the human diet. Chromosomes Number: The chromosomes number define as characteristic number of chromosomes contained in the cell nucleus of a given species is called chromosomes number. The following table shows the nutrient content of green soybean and other major staple foods, each in respective raw form. [104], The soybean was first cultivated in France by 1779 (and perhaps as early as 1740). Phylogenetic analyses of homologous gene pairs have shown that the older of the two putative polyploid duplications is shared by Glycine, Medicago, and Lotus, and therefore occurred no later than in their common ancestor (Pfeil et al., 2005; Cannon et al., 2006), which is estimated from chloroplast phylogenies to have existed around 54 million years ago (MYA; Lavin et al., 2005). Genome-wide association analysis (GWAS) with NJAU 355 K SoySNP array … Soybean [Glycine max (L.) Merr.] Production has dramatically increased across the globe since the 1960s, but particularly in South America after a cultivar that grew well in low latitudes was developed in the 1980s. [161][162], Soybeans contain a high level of phytic acid, which has many effects including acting as an antioxidant and a chelating agent. Soy-based infant formula (SBIF) is sometimes given to infants who are not being strictly breastfed; it can be useful for infants who are either allergic to pasteurized cow milk proteins or who are being fed a vegan diet. "Corn Earworm Biology and Management in Soybeans." Digoxigenin labels were detected using mouse anti-digoxigenin (Roche) followed by AF568 anti-mouse (Invitrogen). Free online. This pattern could be due to autopolyploidy, or, as we suggest is more likely, to the extinction of diploid progenitors (Fig. The maximum number of seeds per pod, or prevalence of 4-bean pods, is largely determined by genetics. Soybeans are a globally important crop, providing oil and protein. Soybean [Glycine max (L.) Merr.] It is possible that the CentGm-1 progenitor had more chromosomes than the CentGm-2 progenitor, although the real scenario cannot be revealed based solely on our current data. Among many uses, soy flour thickens sauces, prevents staling in baked food, and reduces oil absorption during frying.
