GRAS transcription factors emerging regulator in plants growth, development, and multiple stresses.

GRAS transcription factors play multifunctional roles in plant growth, development, and resistance to various biotic and abiotic stresses. The structural and functional features of GRAS TFs have been unveiled in the last two decades. A typical GRAS protein contained a C-terminal GRAS domain with a highly variable N-terminal region. Studies on these TFs increase in numbers and are reported to be involved in various important developmental processes such as flowering, root formation, and stress responses. The GRAS TFs and hormone signaling crosstalk can be implicated in plant development and to stress responses. There are relatively few reports about GRAS TFs roles in plants, and no related reviews have been published. In this review, we summarized the features of GRAS TFs, their targets, and the roles these GRAS TFs playing in plant development and multiple stresses.
