Plant-specific TEOSINTE-BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR1 (TCP) gene family has versatile functions in diverse aspects of plants. However, less research on banana TCPs was done comprehensively. Accordingly, 48 banana TCP genes were characterized on aspects of gene structure, conserved motifs, phylogenetic relationship, and expression patterns. Members of the MaTCP gene family were unevenly distributed among 11 chromosomes and purification selection was the driving force of the MaTCP gene family. Gene duplication analysis indicated that segmental duplication is the major contributor to family expansion. Promoter analysis showed that MaTCPs might be involved in banana growth, development, and abiotic stress responses. Further, the expression of 12 MaTCPs was analyzed by real-time quantitative RT-PCR, and the protein interaction analysis showed that MaPCF10 and MaPCF13 may have an important function in banana fruit development and ripening. These results lay the foundation for further study of the functions of TCP genes in banana.

植物特异性 TEOSINTE-BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR1 (TCP) 基因家族在植物的不同方面具有多种功能。然而，对香蕉 TCPs 的全面研究较少。因此，从基因结构、保守基序、系统发育关系和表达模式等方面对 48 个香蕉 TCP 基因进行了表征。MaTCP基因家族成员在11条染色体中分布不均，纯化选择是MaTCP基因家族的驱动力。基因重复分析表明，节段重复是家庭扩张的主要因素。启动子分析表明，MaTCPs可能参与香蕉的生长、发育和非生物胁迫反应。此外，12 的表达式通过实时定量RT-PCR对MaTCPs进行分析，蛋白质相互作用分析表明， MaPCF10和MaPCF13可能在香蕉果实发育和成熟中具有重要作用。这些结果为进一步研究香蕉中TCP基因的功能奠定了基础。
