Gene expression profiling for seed protein and oil synthesis during early seed development in soybean

摘要: Soybean (Glycine max L.) is one of the most important crops because its high seed contents protein and oil. However, little known about molecular regulation filling during accumulation oil storage products. We identified soybean homologs Arabidopsis genes involved in metabolic pathways carbon precursors, protein, oil, analyzed gene expression patterns immature seeds at 1 2 weeks after flowering (WAF). G. undergoes two rounds whole-genome duplication; number three synthesis more than times higher that Arabidopsis. Among these genes, five were conserved as single-copy 44 copy families consisting seven homolog members. differentially expressed aged between WAF, including CELL WALL INVERTASE, BRANCHED-CHAIN AMINO ACID TRANSAMINASE, PERMEASE, ALDEHYDE REDUCTASE, BIOTIN CARBOXYL CARRIER PROTEIN. Expression analysis duplicated on synteny block revealed had stronger positive correlations their those genes. This study provides novel insights into details associated with pathways. These can be used tools to improve nutrient composition.
