摘要

Taste value of rice grain is one of the key determinants of its quality, regulated through a complex molecular module. It was revealed that amylose is the key determinant of rice grain quality and precise manipulation of amylose could able to enhance rice grain dietary quality. Together with amylose, grain protein content (GPC) also plays a crucial role to maintaining grain quality and higher accumulation glutelin can deteriorate grain quality. Recently, Cao et al. (2025) demonstrated that the OsGATA7-SMOS1-OsGluA2 module enhances grain taste value by reducing GPC in the elite haplotype OsGATA7Hap1 and SMOS1Hap1, providing a holistic approach to improve rice grain quality.
