Abstract: The MYB proteins play important roles in regulating plant responses to environmental stresses. We cloned and functionally characterized a novel MYB-related gene, OsMYBR1, from rice. Our microarray and qRT-PCR analyses showed that its expression was induced by drought and cold in different tissues at various developmental stages. This gene encodes a putative MYB-related protein of 463 amino acid residues. Compared with wild-type (WT) plants, transgenic plants over-expressing OsMYBR1 exhibited much greater tolerance to drought stress and decreased sensitivity to abscisic acid (ABA). Under drought treatment, levels of free proline and soluble sugar were higher in transgenic plants than in the WT. Furthermore, transcriptional expression of four stress-related genes -- OsP5CS1, OsProt, OsLEA3, and OsRab16 -- was significantly increased in transgenic plants under drought stressed conditions and ABA. Our results provide evidence that OsMYBR1 is involved in mediating plant responses to ABA and drought. |
