Comprehensive Genome-Wide Analyses of Poplar R2R3-MYB Transcription Factors and Tissue-Specific Expression Patterns under Drought Stress.

ABSTRACT: R2R3-type MYB transcription factors are implicated in drought stress, which is a primary factor limiting the growth and development of woody plants. The identification of R2R3-MYB genes in the Populus trichocarpa genome has been previously reported. Nevertheless, the diversity and complexity of the conserved domain of the MYB gene caused inconsistencies in these identification results. There is still a lack of drought-responsive expression patterns and functional studies of R2R3-MYB transcription factors in Populus species. In this study, we identified a total of 210 R2R3-MYB genes in the P. trichocarpa genome, of which 207 genes were unevenly distributed across all 19 chromosomes. These poplar R2R3-MYB genes were phylogenetically divided in
