Abstract：Histone acetyltransferases (HATs) mediate histone acetylation and regulate the status of histone
acetylation, which modifies chromatin structure, affects gene transcription and thus plays a crucial regulatory role in plant growth, development and stress responses. However, the systematic analysis of HATs family genes in maize has not been reported yet. In this study, bioinformatics methods were used to analyze the phylogenetic evolution, conserved domain, tissue expression characteristics and expression patterns of the HATs family genes in maize under biological and abiotic stress. It was found that the HATs family genes in maize can be divided into three subfamilies of GANT, MYST and CBP, which all contain multiple conserved domains, and their expression levels were significantly different in different tissues and under different biological/abiotic stress. Real-time PCR technology were used to detect the expression levels of the HATs family genes in maize after hormone treatment. It was found that the HATs family genes showed different expression patterns after jasmonic acid and salicylic acid treatment. These results indicate that the maize HATs family genes play an important role in the growth and development of maize and in response to biological and abiotic stress, which lays a foundation for elucidating the function and regulatory mechanism of maize HATs family genes
