Ectopic expression of the MYB transcription factor of AmROSEA1 from
has been reported to change anthocyanin and other metabolites in several species. In this study, we found that overexpression of
significantly improved the tolerance of transgenic rice to drought and salinity stresses. Transcriptome analysis revealed that a considerable number of stress-related genes were affected by exogenous
during both drought and salinity stress treatments. These affected genes are involved in stress signal transduction, the hormone signal pathway, ion homeostasis and the enzymes that remove peroxides. This work suggests that the
gene is a potential candidate for genetic engineering of crops.
