Characterization and Haplotype Analysis of TaMAPK6-7A Regulating Grain Number in Wheat

Grain number and size are important agronomic traits determining grain yield, and yield improvement depends on exploring functional variations of key regulatory genes. Mitogen-activated protein kinase 6 (MAPK6) plays a key role in crop development; however, its function and variation in wheat remain largely unclear. In this study, we aimed to characterize the function and haplotype variations of TaMAPK6-7A in wheat and develop functional molecular markers for marker assisted breeding. We identif
