摘要: our research identified a novel gene, ZG, which encodes a zinc metalloproteinase with enhanced zinc-dependent proteolytic activity and positively regulates both grain weight and zinc content. Increases in ZG expression led to rice germplasms with significantly increased grain weight and zinc content, suggesting that ZG alleles have substantial potential for breeding high-yield, nutrient-rich rice varieties. Future research will investigate the synergistic regulatory mechanisms and effects of ZG on zinc content and grain weight. Based on our findings, two strategies are proposed: first, to generate plant lines with varying ZG expression levels through gene editing or overexpression; and second, to combine beneficial ZG alleles with other yield- and quality-related genes to optimize rice varieties.
