Abstract:

MicroRNA (miRNA) has the function of regulating gene expression. In order to reveal the evolutionary rule, expression pattern and function of the maize miR395 gene family, we conducted gene mapping, multiple sequence alignment, cis-acting element analysis, secondary structure analysis, target gene prediction and analysis of expression pattern. The results showed that a total of 16 members were identified and all members were located on chromosome 2 and chromosome 10. 19 bases of zma-miR395 gene were identical, which proved that the gene family sequence was very conservative in evolution. There were 18 ABRE-type cis-acting elements, which were speculated to be involved in regulating ABA signaling to improve the maize resistance. Most of the targeted genes were involved in sulfate assimilation, and the zma-miR395 gene family participated in the sulfur metabolism of maize. Transcriptome data analysis showed that some members of the zma-miR395 gene family were down-regulated. The results can provide reference for the related maize gene function analysis.

Key words: maize, miR395 gene family, bioinformatics analysis, target gene, expression pattern
