Anthocyanins from the black soybean seed coat are known to have many pharmaceutical effects. However, black soybean seed contains antinutritional factors such as lipoxygenase, Kunitz trypsin inhibitor (KTI), lectin, and stachyose. The genetic removal of these components will improve the nutritional value of black soybean seed. The objective of this research was to breed a soybean strain with the black seed coat color, green cotyledon color, and tetra recessive allele (lox1lox2lox3/lox1lox2lox3-ti/ti-le/le-rs2/rs2) for lipoxygenase, KTI, lectin, and stachyose components. Eight parents were used to breed the tetra null strain. Analysis of lipoxygenase, KTI, lectin, and stachyose components in mature seeds was conducted by SDS-PAGE, Western blot, and HPLC. The soybean line with the black seed coat color, the green cotyledon color, a large seed size, and tetra recessive alleles has purple flowers, a determinate growth habit, and brown pods at maturity. The stem height of the breeding line was 52.3 cm. The 100-seed weight of the breeding line was 35.2 g and the yield (Ton/ha) was 2.50. The stachyose content of the breeding line was 3.30 g/kg. This is the first soybean strain with the black seed coat color, the green cotyledon color, a large seed size, and tetra null alleles (lox1lox2lox3/lox1lox2lox3-ti/ti-le/le-rs2/rs2, low content of stachyose, free of lipoxygenase, KTI, and lectin proteins).

The soybean seed is highly susceptible to field weathering and mechanical damage which adversely affect its longevity. Mechanical injury can occur at any time during harvesting, drying and storage conditioning of seeds. The seed coat color and leachate conductivity of soybean has been correlated with seed longevity and black seed coat color has been reported to be positively correlated with better seed longevity. In order to understand the physico-chemical attributes related to soybean seed longevity, biochemical and molecular analysis of the parents exhibiting black (Birsasoya-1) and yellow seed coat colour (EC 241780) and the eleven F3 progenies of the cross exhibiting brown, yellow and black seed coat colour was carried out. The results revealed that vita-E, lignin, calcium content and activity of antioxidative enzymes appeared to be positively correlated with soybean seed longevity and levels were higher in black and brown seed coat color progenies. The lipid peroxidation rate was inversely related to membrane injury caused by ROS and comparatively much less lipid peroxidation rate was recorded in black and brown seed coat colour parents and progenies having better seed longevity. The SSR primers Satt162, Satt523 and Satt453 which are either linked with seed coat colour and seed permeability exhibited a specific size allelic fragments in soybean genotypes and crosses with better seed longevity.

ABSTRACTSeed coat color is an important part of consumer preferences for cowpea (Vigna unguiculata L. Walp). Color has been studied in numerous crop species and has often been linked to loci controlling the anthocyanin biosynthesis pathway. This study makes use of available resources, including mapping populations, a reference genome, and a high-density single nucleotide polymorphism genotyping platform, to map the black seed coat and purple pod tip color traits in cowpea. Several gene models encoding MYB domain protein 113 were identified as candidate genes. MYB domain proteins have been shown in other species to control expression of genes encoding enzymes for the final steps in the anthocyanin biosynthesis pathway. PCR analysis indicated that a presence/absence variation of one or more MYB113 genes may control the presence or absence of black pigment. A PCR marker has been developed for black seed coat color in cowpea.

Seed coat color is probably a determinant factor in the antibiosis mechanism of developing resistance to safflower fly (Acanthiophilus helianthi). The purpose of this study was to determine the relationship between the phytochemical content of safflower (Carthamus spp.) seed coat extract with the seed coat color and the damage caused by safflower fly. To this end, germplasm consisting of the cultivated species (C111, with a white seed coat), the wild species (Glaucus and lanatus with a black seed coat; Azar with a brown seed coat), and a breeding line (A82 with a black seed coat) was formed. After cultivating the genotypes, the seed loss (%) and its relationship with the polyphenolic compounds and Cyanidin-3-glucoside of the seed coat extract were examined. Agricultural and phytochemical trait data were analyzed through a completely random block design. With a significant difference from other samples, a minimum damage percentage was observed in Lanatus, Glaucus, and A82 genotypes with a black coat (P < 0.05). The concentration of phenolic compounds, that is, chlorogenic acid, caffeic acid, and p-coumaric acid, except for ferulic acid, was almost equal in all genotypes. However, there was an inverse and direct relationship between the concentration of four polyphenolic compounds (rutin, apigenin, quercetin, and ferulic acid) and Cyd-3-glu content with resistance safflower fly, respectively. In general, flavonoid compounds, that is, rutin, quercetin, and apigenin, affect the resistance probably through antibiosis mechanism so that there was a negative relationship between the concentration of these compounds and resistance to safflower fly.

Background: In soybean yellow seed coat is preferred in the market, however, colored ones are currently gaining attention because of their medicinal and nutritive values; besides. Hence it is essential to breed varieties with desired seed coat colour. Methods: Twelve genotypes with six each having yellow and black seed coats were screened with fourteen primers linked to seed coat colour governing loci. Result: Out of them twelve primers showed polymorphism. Monomorphism was observed with both T loci specific and two of the three R loci specific primers. However I locus specific primers i.e. SM303, SM305 and TR showed polymorphism shared by their seed coat color. SM303 amplified a 180 bp sized band in yellow seed coated genotypes and a 130 bp band in black seed coated genotypes. SM305 amplified dual bands with a 200bp band being monomorphic and an additional band (192-216 bp range) present in only yellow seed coated genotypes, of which a 208 bp band was shared by four yellow seed coated genotypes. Cold induced seed coat discoloration specific TR primer generated bands of different size ranges in yellow seed coated (336-344 bp) and black seed coated genotypes (300-320), of which a 340 bp band was shared by four yellow seed coated genotypes.

Abstract Background: Seed coat color is a key agronomic characteristic in sesame (Sesamum indicum) since it is strongly linked to seed oil, proteins, and lignans content and it influences consumer preferences. Even though some QTL and candidate genes have been detected for sesame seed coat color, the mechanism and regulation of black pigmentation are not entirely understood. This study provides an overview of developing seeds transcriptome of two varieties of sesame “Zhongfengzhi No.1” (white seed) and “Zhongzhi No.33” (black seed) and shed light on genes involving in black seed formation.Results: Both black and white sesame showed similar trend expressed genes with the numbers increased at the early stages of seed development. The differentially expressed genes (DEGs) number increased with seed development in the two sesame varieties. We examined the DEGs and uncovered that the early stage, which is from 8 to 17 days post-anthesis (DPA) plays an important role in black pigment biosynthesis and accumulation. The gene expression patterns were consistent with the seed color change. Besides, we studied the shared DEGs between the black and white sesame. We figured out 17 candidate genes associated with pigments biosynthesis in black sesame seed including 2 chalcone synthase genes SIN_1018961 and SIN_1018959 which may function in the phenylpropanoid pathway. 5 of these candidate genes, SIN_1006242 and SIN_1016759/PPO, SIN_1026689 and SIN_1006025, SIN_1025056 are located on chromosomes 4, 8 and 11 respectively, in conformity with previous QTL mapping. These genes were believed to play a major role in black seed development in sesame. Conclusion: This work illuminated the different expression profiles in black and white sesames and unfolded pivotal stages and a catalog of candidate genes associated with black seed formation in sesame. These findings provide a vast transcriptome dataset and list of genes that will be targeted for functional studies related to the molecular mechanism involved in biosynthesis and regulation of seed coat color in sesame and for molecular breeding of high-quality sesame varieties.
