Salinity adaptability responses of wild soybean (Glycine soja Sieb. & Zucc.) under high saline soil stress over whole growth period

Abstract Soybean seeds contain high levels of oil and protein providing 69% and 57% of dietary protein and oil respectively. Although many quantitative trait loci for 100-seed weight (100SW), protein content (PRC) and oil content (OIC) have been reported, their genetic controls in soybeans remain unclear. The QTL–allele constitution of three traits in the Sichuan and Chongqing eco-regions population (SCLBP) was studied using a representative sample composed of 228 accessions tested under four environments and analyzed based on 135 SSR and 107081 valid SNP (single nucleotide polymorphism linkage) markers. The varied range of 100SW, PRC and OIC of SCLBP were 4.82-33.35, 36.47-49.75 and 14.68-21.77 among accessions, respectively. The heritability (h2) and genetic coefficient of variation (GCV) of three traits were high. As a result, 26, 33 and 31 QTLs were found by SSR to be associated with 100SW, PRC and OIC, respectively. The allele of Sat_260 for 100SW was detected in 4 environments. In addition, 28, 198 and 250 loci for 100SW, PRC and OIC were found by SNP using mixed linear model (MLM), respectively. Further SNP haplotype analysis showed that 13, 35 and 60 blocks for 100SW, RPC and OIC were found. The block of Gm11_9895764-9917646 for 100SW was simultaneously detected in four environments. Among these QTLs, 1, 5, and 7 for 100SW, PRC and OIC were found by two methods of SSR and SNP at the same time. A majority of these QTLs overlapped with the previously reported loci. However, 9, 11 and 9 loci for 100SW, PRC and OIC using SSR and 3, 5 and 8 for 100SW, PRC and OIC haven’t been reported using SNP in the study, respectively. Moreover, the genes of Glyma.11g130800, Glyma.13g217000 and Glyma.08g122600 were considered to be the most likely genes controlling 100SW, PRC and OIC, respectively. Our findings provide evidence for mixed major plus polygenes inheritance for three traits and an extended understanding of their genetic architecture for molecular dissection and breeding utilization in soybeans.

Color Gene

The enzyme flavonoid 3′,5′-hydroxylase (F3′5′H) plays an important role in producing anthocyanin pigments in soybean. Loss of function of the W1 locus encoding F3′5′H always produces white flowers. However, few color variations have been reported in wild soybean. In the present study, we isolated a new color variant of wild soybean accession (IT261811) with pinkish-white flowers. We found that the flower’s pinkish-white color is caused by w1-s3, a single recessive allele of W1. The SNP detected in the mutant caused amino acid substitution (A304S) in a highly conserved SRS4 domain of F3′5′H proteins. On the basis of the results of the protein variation effect analyzer (PROVEAN) tool, we suggest that this mutation may lead to hypofunctional F3′5′H activity rather than non-functional activity, which thereby results in its pinkish-white color.

Free Amino Acid Content

AbstractWild soybean (Glycine soja) is a valuable genetic resource for soybean improvement. Seed composition profiles provide beneficial information for the effective conservation and utilization of wild soybeans. Therefore, this study aimed to assess the variation in free amino acid abundance in the seeds of wild soybean germplasm collected in Japan. The free amino acid content in the seeds from 316 accessions of wild soybean ranged from 0.965 to 5.987 mg/g seed dry weight (DW), representing a 6.2-fold difference. Three amino acids had the highest coefficient of variation (CV): asparagine (1.15), histidine (0.95) and glutamine (0.94). Arginine (0.775 mg/g DW) was the predominant amino acid in wild soybean seeds, whereas the least abundant seed amino acid was glutamine (0.008 mg/g DW). A correlation network revealed significant positive relationships among most amino acids. Wild soybean seeds from different regions of origin had significantly different levels of several amino acids. In addition, a significant correlation between latitude and longitude of the collection sites and the total free amino acid content of seeds was observed. Our study reports diverse phenotypic data on the free amino acid content in seeds of wild soybean resources collected from throughout Japan. This information will be useful in conservation programmes for Japanese wild soybean and for the selection of accessions with favourable characteristics in future legume crop improvement efforts.

AbstractA half diallel cross between five divergent sunflower genotypes was evaluated under two contrast locations of Kafr El-Hamam (fovourable soil as a control) and Tag Al-Ezz (as salt affected soil) Agricultural Research Stations using randomized complete block design with three replications. High significance variation among genotypes and their components was detected for all studied traits at both and combined locations. Selection in early generations would be effective at both locations for improving days to 50 % flowering, days to physiological maturity, plant height, head diameter, No. of green leaves plant
