Summary, etc. MYB transcription factors (TFs) are one of the largest TF families, and R2R3-type MYB TFs participate in the multiply abiotic stress responses in wheat. In this study, an R2R3-type MYB gene Myb protein colourless 1 located on chromosome D (named TaMpc1-D4), was cloned from wheat. TaMpc1-D4-GFP protein was localized in the nucleus. Overexpression of TaMpc1-D4 reduced drought tolerance in transgenic Arabidopsis lines, which was supported by the lower germination rate, the shorter root length, a higher level of O2− and malonaldehyde (MDA), the decreased proline content, and limited activities of peroxidase (POD), superoxide dismutase (SOD), and catalase (CAT). Furthermore, P5CS1, RD29A, RD29B, DREB2A, ABF3, CBF1, CBF2, CBF3, ERF1, POD1, SOD (Cu/Zn), and CAT1 genes related to the stress and antioxidant system were remarkably down-regulated in TaMpc1-D4 transgenic Arabidopsis lines under drought stress. Silencing TaMpc1-D4 expression in wheat enhanced the relative water content (RWC), the proline content, and the activities of antioxidant enzymes, and activated stress-related and antioxidant-related genes (DREB1, DREB3, ERF3, ERF4b, ABF, P5CS, POD, SOD (Fe), and CAT). Taken together, these results indicated that TaMpc1-D4 negatively modulated drought tolerance by regulating the capacity of the enzyme system and the expression of stress-related and antioxidant-related genes.
