different development stages and abiotic stresses of bananas. Results showed that 15 MaDof genes were up-regulated throughout the fruit development, suggesting that they may play important roles in fruit development. In abotic stresses, most MaDof gene expressions were down-regulated, suggesting that these genes played a negative regulation role in abotic stress. In summary, this study is the first comprehensive genome-wide analysis of the Dof gene family in bananas. A total of 74 MaDof gene family members were identified and could be grouped into four classes. Banana Dof proteins appear to have structural diversities that may indicate their diverse function. The expression levels of MaDof in different development stages and abiotic stress treatments in fruits were characterized. Thus, the systematic analysis of the Dof gene family and the preliminary results presented here may provide a foundation for further research on the biological functions of Dof proteins in bananas, which will promote their application in banana breeding.
