Abstract excerpt
Leaf width (LW) is a critical determinant of maize architecture and yield. To uncover its genetic basis, we performed a genome-wide association study (GWAS) on 348 maize inbred lines and identified ZmCKX6, encoding cytokinin oxidase/dehydrogenase, as a key gene associated with LW. Natural variation in the ZmCKX6 promoter significantly influenced its expression levels, leading to differences in LW across various...
