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.
BAHD 家族在植物中参与多种生物学功能，包括次生代谢物合成、提高非生物/生物胁迫抗性以及影响果实品质。然而，香蕉作为一种重要的水果作物，BAHD 的相关知识有限。在本研究中，鉴定了 46 个香蕉 BAHD 基因（MaBAHDs），并根据系统发育分析将其分为四个组。同一组中的大多数 MaBAHD 基因具有相似的保守基序和遗传结构。两种香蕉品种中的 MaBAHD 基因具有相似的表达模式，更多的基因在根中表现出高表达。从两个香蕉品种获得的综合 MaBAHD 基因表达模式提供了有关其参与果实发育、成熟以及对非生物/生物胁迫响应的有价值信息，表明它们在这些过程中发挥关键作用。MaBAHD 基因的系统分析为进一步的基因功能分析和在遗传改良香蕉品种中的潜在应用提供了基础见解。
