Rice Flowering Locus T 1 plays an important role in heading date influencing yield traits in rice

Abstract Important role of flowering genes in enhancing grain productivity in rice has become well recognized for a number of key genes regulating the florigen production, but little has been known for the two florigen genes themselves. In this study, pleiotropism of Rice Flowering Locus T 1 (RFT1),...
