Above 70% of storage proteins of soybean were composed with-coglycinine and glycinine. Characterisation of seed components and global gene expression analysis was performed with most-glycinne-deficient cultivar, Nanahomare.The constituents of seed were almost the same as those of control cultivar, Tmahomare,but free amino acid contents were highly increased in Nanahomare. The gene expression in developing seeds were not so different. Some seed maturation proteins and two stress related genes, glutathione S-transferase and ascorbate peroxidase, were more expressed in Nanahomare.
