“…Enhanced tolerance to abiotic stresses was suggested to be accomplished via regulation of stress-mediated ABA biosynthesis. 46 Plants have developed elaborate and complex mechanisms to survive under abiotic stress conditions. Several line of evidences have implicated role of MYB protein in regulation of abiotic stress tolerance in plant genome.…”

Plants have developed highly efficient and remarkable mechanisms to survive under frequent and extreme environmental stress conditions. Exposure of plants to various stress factors is associated with coordinated changes in gene expression at the transcriptional level and hence transcription factors, such as those belonging to the MYB family play a central role in triggering the right responses. MYB transcription factors have been extensively studied in regard of their involvement in the regulation of a number of such stress responses in plants. Genetic and molecular biological studies, primarily in Arabidopsis, have also begun to unravel the role of MYB transcription factors in the epigenetic regulation of stress responses in plants. This review focuses on the role of MYB transcription factors in the regulation of various stress responses in general, highlighting on recent advances in our understanding of the involvement of this class of transcription factors in epigenetic regulation of stress response in plant genome.

“…However, the OsMYB4 network was independent of the DREB/CBF pathway (Park et al, 2010). In addition, several members belonging to the MYB family, including OsMYB2 (Yang et al, 2012), OsMYB511 , CMYB1 , and OsMYB48-1 (Xiong et al, 2014), also were reported for their roles in cold stress regulation, but their molecular mechanisms have not been clearly revealed.…”

The OsMYB30 Transcription Factor Suppresses Cold Tolerance by Interacting with a JAZ Protein and Suppressing β-Amylase Expression

Cold stress is one of the major limiting factors for rice (Oryza sativa) productivity. Several MYB transcriptional factors have been reported as important regulators in the cold stress response, but the molecular mechanisms are largely unknown. In this study, we characterized a cold-responsive R2R3-type MYB gene, OsMYB30, for its regulatory function in cold tolerance in rice. Functional analysis revealed that overexpression of OsMYB30 in rice resulted in increased cold sensitivity, while the osmyb30 knockout mutant showed increased cold tolerance. Microarray and quantitative real-time polymerase chain reaction analyses revealed that a few b-amylase (BMY) genes were down-regulated by OsMYB30. The BMY activity and maltose content, which were decreased and increased in the OsMYB30 overexpression and osmyb30 knockout mutant, respectively, were correlated with the expression patterns of the BMY genes. OsMYB30 was shown to bind to the promoters of the BMY genes. These results suggested that OsMYB30 exhibited a regulatory effect on the breakdown of starch through the regulation of the BMY genes. In addition, application of maltose had a protective effect for cell membranes under cold stress conditions. Furthermore, we identified an OsMYB30-interacting protein, OsJAZ9, that had a significant effect in suppressing the transcriptional activation of OsMYB30 and in the repression of BMY genes mediated by OsMYB30. These results together suggested that OsMYB30 might be a novel regulator of cold tolerance through the negative regulation of the BMY genes by interacting with OsJAZ9 to fine-tune the starch breakdown and the content of maltose, which might contribute to the cold tolerance as a compatible solute.

“…The tolerance to salinity and drought stresses of transgenic rice overexpressing OsMYB48-1 was significantly improved. Overexpression of OsMYB48-1 regulated the expression of some stress responsible genes, such as RAB16C, RAB16D, RAB21 and LEA3 under drought stress conditions [32]. The expression of…”

Ectopic expression of the MYB transcription factor of AmROSEA1 from Antirrhinum majus has been reported to change anthocyanin and other metabolites in several species. In this study, we found that overexpression of AmRosea1 significantly improved the tolerance of transgenic rice to drought and salinity stress. Transcriptome analysis revealed that a considerable amount of stress-related genes were affected by exogenous AmRosea1 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 AmRosea1 gene is a potential candidate for genetic engineering of crops.
