MYB is one of the largest transcription factors family and has a wide range of biological functions in plants. Based on the full-length transcriptome database of Blumea balsamifera, DNAMAN 6.0, MEGA 5.05 software and ProtParam, WebLogo and SOPMA online sites were used to analyze and predict the types, physicochemical properties, advanced structure of amino acid sequence, conserved domain and phylogenetic evolution of MYB transcription factor in B. balsamifera, The results showed that 127 BbMYB genes were extracted, and 47 protein sequences with MYB conserved domains were predicted. According to the domain, they could be divided into 1R-BbMYB and R2R3-MYB. Meanwhile, the R2-BbMYB and R3-BbMYB motifs contained three conserved tryptophans, while R1-BbMYB contained only two. Morever, all proteins of MYB family in B. balsamifera were hydrophilic with high thermal stability and rich in basic amino acids. And most of the proteins were irregular curls except the R2R3-BbMYB3, R2R3-BbMYB4 and 1R-BbMYB15. The MYB family of B. balsamifera evolved into two major categories and six subcategories by comparing with the evolutionary tree of Arabidopsis thaliana. It would provide a method for further research on the functional identification of the MYB family in B. balsamifera by the adjacent or evolutionary relationship with the same function.
