Quantitative Trait Loci (QTL) Analysis of Seed Protein and Oil Content in Wild Soybean ( Glycine soja )

Soybean seeds consist of approximately 40% protein and 20% oil, making them one of the world's most important cultivated legumes. However, the levels of these compounds are negatively correlated with each other and regulated by quantitative trait loci (QTL) that are controlled by several genes....

Description
Summary:Soybean seeds consist of approximately 40% protein and 20% oil, making them one of the world's most important cultivated legumes. However, the levels of these compounds are negatively correlated with each other and regulated by quantitative trait loci (QTL) that are controlled by several genes. In this study, a total of 190 F and 90 BC F plants derived from a cross of Daepung ( ) with GWS-1887 ( , a source of high protein), were used for the QTL analysis of protein and oil content. In the F populations, the average protein and oil content was 45.52% and 11.59%, respectively. A QTL associated with protein levels was detected at Gm20_29512680 on chr. 20 with a likelihood of odds (LOD) of 9.57 and an R of 17.2%. A QTL associated with oil levels was also detected at Gm15_3621773 on chr. 15 (LOD: 5.80; R : 12.2%). In the BC F populations, the average protein and oil content was 44.25% and 12.14%, respectively. A QTL associated with both protein and oil content was detected at Gm20_27578013 on chr. 20 (LOD: 3.77 and 3.06; R 15.8% and 10.7%, respectively). The crossover to the protein content of BC F population was identified by SNP marker Gm20_32603292. Based on these results, two genes, (S-adenosyl-l-methionine-dependent methyltransferases) and (oxidoreductase, 2-oxoglutarate-Fe(II) oxygenase family protein), in which the amino acid sequence had changed and a stop codon was generated due to an InDel in the exon region, were identified.
