Research progress of GRAS transcription factors in plant growth and development and abiotic stress response
GRAS(GAI-RGA-and-SCR)is a family of transcription factors that is unique to plants and has been identified more frequently in recent years,and plays an important role in various physiological and biochemical processes such as plant growth and development and abiotic stress response.GRAS proteins activate or inhibit the expression of downstream genes by combining to a specific DNA sequence,which affect the division and development of plants,hormone signal transfers,and adversity adaptation.In this paper,we summarize the structural characteristics and expression properties of GRAS transcription fac-tors,and focus on the role of GRAS in plant growth and development and the progress of abiotic stress re-sponse(salt,drought,low temperature,etc.).This paper provides a theoretical references for the in-depth study of GRAS transcription factors on plant growth regulation,metabolism and response mechanisms to environmental stresses.
