The BAHD family is involved in different biological roles in plants, including secondary metabolite synthesis, improving abiotic/biotic stress resistance, and influencing fruit quality. However, the knowledge about BAHD in banana, an important fruit crop, is limited. In this study, 46 banana BAHD genes (MaBAHDs) were identified and divided into four groups according to phylogenetic analysis. Most of the MaBAHD genes in the same group presented similar conserved motifs and genetic structures. MaBAHD genes have similar expression patterns in two banana varieties, and more genes showed high expressions in the roots. The comprehensive MaBAHD gene expression patterns obtained from two varieties of banana showed valuable information regarding their participation in fruit development, ripening, and response to abiotic/biotic stresses, suggesting that they play key roles in these processes. The systematic analysis of MaBAHD genes offered basic insight for further gene functional assays and potential applications in genetically improving banana cultivars.
