Research Abstract

This research project aims for understanding mechanisms of seed storage protein (SSP) synthesis in rice endosperm. We generated several transgenic rice plants with reduced SSPs, in which recombinant products can use surplus amino acids. Rice seed specific transcription factors RISBZ1 and RPBF regulate SSP gene expression redundantly. RISBZ1 and RPBF are regulatory factors of endosperm quality.
