Welcome to GRAS !

The GRAS transcription factors (TFs) are plant-specific regulating proteins that have been widely studied in the past decade. The name of GRAS proteins was derived from the three first identified members of the gene family: gibberellic acid insensitive (GAI), repressor of GA1-3 mutant (RGA), and scarecrow (SCR). GRAS protein sequences consisted of 400-770 amino acid residues, which exhibited highly conserved C-terminal regions and variable N-terminals. Commonly, the GRAS domains were determined by the conserved carboxyl-terminal regions, and could be divided into five motifs: leucine-rich region I (LHRI), VHIID, leucine-rich region II (LHRII), PFYRE, and SAW. GRAS proteins broadly participated in many critical processes such as signal transductions, root radial elongations, axillary shoot meristem formations and stress responses in plants.
