Here, we report that SDG721 （SET-domain group protein 721） and SDG705 are involved in regulating rice development. SDG721 and SDG705 encode TRITHORAX-Iike proteins, which appear to modulate H3K4 methylation levels. Loss of SDG721 and SDG705 function resulted in GA-deficient phenotypes, including semi-dwarfism, reduced cell length, and reduced panicle branching.展开更多
