Comparison of soybean and common bean seeds. (a) Comparing the top 1,500 expressed genes (regardless of seed stage) in soybean (as reported by Severin et al. ) and common bean seeds. (b and c) Expression profiles of genes involved in fatty acid and starch biosynthesis pathways in developing seed tissues. Glb2 (GLABARA 2), ACoAC (Acetyl CoA Carboxylase), FAD2 and FAD3 (fatty acid desaturase), AAP1 and 2 (amino acid transporter), PEPC (phosphoenolpyruvate carboxylase), STS (starch synthase), STB (starch branching enzyme), SS (sucrose synthase). (b) Gene expression profiles in common bean, (c) Gene expression profiles in soybean (as reported by Severin et al. ).
