Abstract excerpt

KEY MESSAGE: We developed an efficient promoter editing method to create different weak Ehd1 alleles in elite japonica rice variety ZJ8 with slightly delayed heading and improved yield for use in breeding. Heading date is an important agronomic trait of rice (Oryza sativa) that determines the planting areas and cultivation seasons of different varieties, thus affecting final yield. Early heading date 1 (Ehd1) is...
