The Wheat MYB Transcription Factor TaMYB³¹ Is Involved in Drought Stress Responses in Arabidopsis.

ABSTRACT: Drought is one of the major environmental stresses limiting crop growth and production. MYB family transcription factors play crucial roles in response to abiotic stresses. Previous studies found that TaMYB31 is transcriptionally induced by drought stress. However, the biological functions of TaMYB31 in drought stress responses remained unknown. In this study, three TaMYB31 homoeologous genes from hexaploid wheat, designated TaMYB31-A, TaMYB31-B, and TaMYB31-D, were cloned and characterized. Expression analysis showed that TaMYB31 genes have different tissue expression patterns, and TaMYB31-B has relatively high expression levels in most tested tissues. All the three homoeologs were up-regulated by polyethylene glycol (PEG) 6000 and abscisic
