This study identifies of a zinc metalloproteinase, ZG, that positively regulates both zinc content and grain size in rice. ZG's proteolytic activity increases with higher zinc ion concentrations. These findings, along with haplotype analysis in global rice cultivars, highlight its strong potential for enhancing both yield and nutritional value in rice breeding.
本研究鉴定出一种锌金属蛋白酶ZG，它对水稻中的锌含量和籽粒大小均具有正向调控作用。ZG的蛋白水解活性随锌离子浓度升高而增强。这些发现，连同对全球水稻品种的单倍型分析，凸显了其在水稻育种中提高产量和营养价值的巨大潜力。
