“…Samples were dried in a vacuum oven at 40 • C for 24 h and cool down at room temperature. Isoflavone extraction was done by previously published protocol with small modification [18]. Approximately 25.0 mg of each replicate was mixed with 2.5 mL MeOH/H 2 O (80/20 v/v) solution and subjected to ultrasonic extraction (40 kHz) for 3 h with an ice water-bath.…”

Water imbalance condition (WIC) in a maize-soybean relay intercropping system is the main abiotic stress limiting biomass production and seed yield and, consequently, seed-quality. This experiment was started to study the effects of WIC on soybean, in which two soybean genotypes ND12 and C103 were grown in pots with roots split equally between two soil column and six WIC treatments (%) T1 (100), T2, (100:50), T3 (100:20), T4 (50:50), T5 (50:20), and T6 (20:20) field capacity on both sides of soybean roots were used. Results showed that both genotypes responded significantly to WIC treatments for all the parameters; however, the level of response differed between genotypes. Maximum osmoprotectants (except proline), biomass, yield and yield-related traits and superior seed quality were observed with ND12. Among WIC treatments, T2 and T3 produced 94% and 85%, and 93% and 81% of T1 biomass and yield, respectively. Similarly, treatments T2 and T3 also improved the oil quality by maintaining the content of unsaturated fatty acids and isoflavone content, while opposite trends were observed for protein content. Overall, moderate water reduction (T2 and T3) can improve soybean seed-quality and by selecting drought-resistant genotypes we can increase the soybean yield under intercropping systems.

“…Storage also had a strong influence on the metabolism of fatty acids. As the storage duration increased, the concentrations of glucoside and aglycon increased, whereas those of acetyl glucoside and malonyl glucoside decreased after 3 years storage (Liu et al, 2017). Classical genetic studies have shown that resistance of soybean seed to storage is mainly controlled by polygenes, and recently by molecular marker mapping, some QTLs were found to be associated with storage resistance (Dargahi et al, 2014).…”

“…Unpigmented coat seeds deteriorated more rapidly during storage than those with pigmented. After aging, the vigor of black seed is higher than those of the yellow seed (Singh and Ram, 1986;Liu et al, 2017). The multiple hard layers of the seed coat of darkcolored soybean, especially those of black soybean, lead to resistance to water absorption, and then reduce seed moisture content, thus causing seed dormancy (Mullin et al, 2001).…”

“…Soybean seeds are rich in protein and fat, and are prone to loss of vigor noticeably in natural storage and germplasm preservation in gene banks, leading to necessary seed production and multiplication about every 1-3 years in agricultural practice (Liu et al, 2017). Genetic factors played an important role in soybean seed storability (Kueneman, 1983;Singh and Ram, 1986).…”

Total 246 lines from southern China were subjected to treatments under natural conditions for 4 years and artificial aging under high temperature (45°C) and high humidity (95% RH) for 5 days. Seed vigor measured by the germination rate (GR), normal seedling rate (NSR), full seedling length (FSL), seedling shoot length (SSL) and seedling root length (SRL). The significant decrease was observed in the five traits with high heritability and variation. Correlation coefficients among the five traits were highly significant (r>0.700), and significant correlation of these indicators between two treatments was also found with the highest r values of 0.405 for GR. Only seed protein content had weak significant positive correlation with FSL and SSL. According to the grading standard, there were five categories: high tolerance, tolerance, middle tolerance, sensitivity and high sensitivity. 12 lines with good tolerance level were identified, and will be utilized in future breeding programs to improve seed longevity in soybean.

“…Among other phytochemicals, anthocyanin is one of the key components that exert antioxidant effects and determine the seed colors of soybean. A recent study reported that dark-colored seeds (i.e., seeds with higher anthocyanin contents) had positive effects for the grain storage compared to light-colored seeds [3], because anthocyanins and other polyphenolic compounds contributed to resisting stresses during the storage [4,5]. As a result, longer seed storability leads to beneficial effects on seed germination, growth vigor, nutritional contents, and overall seed quality.…”

Dissecting seed pigmentation-associated genomic loci and genes by employing dual approaches of reference-based and k-mer-based GWAS with 438 Glycine accessions

et al. 2020

The soybean is agro-economically the most important among all cultivated legume crops, and its seed color is considered one of the most attractive factors in the selection-by-breeders. Thus, genome-wide identification of genes and loci associated with seed colors is critical for the precision breeding of crop soybeans. To dissect seed pigmentation-associated genomic loci and genes, we employed dual approaches by combining reference-based genome-wide association study (rbGWAS) and k-mer-based reference-free GWAS (rfGWAS) with 438 Glycine accessions. The dual analytical strategy allowed us to identify four major genomic loci (designated as SP1-SP4 in this study) associated with the seed colors of soybeans. The k-mer analysis enabled us to find an important recombination event that occurred between subtilisin and I-cluster B in the soybean genome, which could describe a special structural feature of ii allele within the I locus (SP3). Importantly, mapping analyses of both mRNAs and small RNAs allowed us to reveal that the subtilisin-CHS1/CHS3 chimeric transcripts generate and act as an initiator towards ‘mirtron (i.e., intron-harboring miRNA precursor)’-triggered silencing of chalcone synthase (CHS) genes. Consequently, the results led us to propose a working model of ‘mirtron-triggered gene silencing (MTGS)’ to elucidate a long-standing puzzle in the genome-wide CHS gene silencing mechanism. In summary, our study reports four major genomic loci, lists of key genes and genome-wide variations that are associated with seed pigmentation in soybeans. In addition, we propose that the MTGS mechanism plays a crucial role in the genome-wide silencing of CHS genes, thereby suggesting a clue to currently predominant soybean cultivars with the yellow seed coat. Finally, this study will provide a broad insight into the interactions and correlations among seed color-associated genes and loci within the context of anthocyanin biosynthetic pathways.
