Aminoacyl-tRNA synthetases play a critical role in protein synthesis by catalyzing the covalent attachment of amino acids to their cognate tRNAs. However, the role of aminoacyl-tRNA synthetases in the transition from vegetative to reproductive growth in plants remains poorly understood. In this study, a rice (Oryza sativa) glycyl-tRNA synthetase 3, OsGlyRS3, was found to impact heading date in rice. Flowering in osglyrs3, a mutant line containing a T-DNA insertion in OsGlyRS3, was advanced by approximately 2 weeks compared to wild type. Expression analysis of flowering regulator genes showed that transcript levels of Heading date 1 (Hd1), Heading date 3a (Hd3a), and OsMADS51 were elevated in osglyrs3. These data indicate that the loss of OsGlyRS3 activity induces the expression of flowering-activating genes, resulting in early flowering.
