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.
