INTRODUCTION: The three-amino-acid-loop-extension (TALE) of the homeobox superfamily genes plays important roles in plant growth, development, and responses to environmental stress. Although TALE members have been identified in various species, they have not been systematically characterized in maize and their expression profiles under ABA hormone and abiotic stress are unknown. METHODS: Bioinformatics methods were employed to identify the TALE family genes in the maize genome. The expression levels of RESULTS: In this study, we identified 52 TALE members in maize, which can be divided into two subfamilies, KNOX and BELL. ZmKNOXs and ZmBELLs can be further divided into two subclasses based on the domains they contain. The protein characterizations and gene structures in the same subclass were similar, whereas they were distinct across different subclasses. There were 18 collinear gene pairs in maize genome. Inter-species evolutionary analyses showed that TALE family genes of maize were more homologous to monocotyledons than to dicotyledons. The promoter regions of DISCUSSION: We identified TALE superfamily members in maize and conducted a comprehensive and systematic analysis. These results can lay the foundation for analysis of the functions of
