Abstract

Abstract: Aux/IAA gene family is a kind of transcription factors in plants, which plays a regulatory role in the process of auxin regulating plant growth. In this study, the structural characteristics and gene expression patterns of Aux/IAA transcription factors in maize ( Zea mays L.) were analyzed by bioinformatics method, and 32 Aux/IAA genes from Arabidopsis and 40 Aux/IAA genes from maize were screened for phylogenetic evolution. It was inferred that the gene family was an ancient and huge gene family by evolutionary tree. The numbers of Aux/IAA genes distributed on chromosome 3 and 6 are the largest. Subcellular localization prediction indicated that the gene family mainly played a role in the nucleus. Thermogram analysis showed that a small number of genes were highly expressed in specific tissues. In addition, GRMZM2G115357 was highly expressed under the condition of high osmotic pressure, which might play a role in the process of resistance to high osmotic stress in maize. The results of this study promote the understanding of Aux/IAA family genes and lay a foundation for the functional study of Aux/IAA family genes at the molecular level. Core Ideas: The bioinformatics analysis of Aux/IAA transcription factor gene family in maize had not been analyzed. Therefore, we used bioinformatics methods to systematically analyze Aux/IAA transcription factors in maize, in order to further clarify the role of Aux/IAA transcription factors.
