Genome-Wide Characterization and Analysis of R2R3-MYB Genes Related to Fruit Ripening and Stress Response in Banana (Musa acuminata L. AAA Group, cv. 'Cavendish').

ABSTRACT: MYB is an important type of transcription factor in eukaryotes. It is widely involved in a variety of biological processes and plays a role in plant morphogenesis, growth and development, primary and secondary metabolite synthesis, and other life processes. In this study, bioinformatics methods were used to identify the R2R3-MYB transcription factor family members in the whole Musa acuminata (DH-Pahang) genome, one of the wild ancestors of banana. A total of 280 MaMYBs were obtained, and phylogenetic analysis indicated that these MaMYBs could be classified into 33 clades with MYBs from Arabidopsis thaliana. The amino acid sequences of the R2 and R3 Myb-DNA binding in all MaMYB protein sequences were quite conserved, especially Arg-12, Arg-13, Leu-23, and Leu-79. Distribution mapping result
