Abstract: To understand the miR169 gene family in oilseed rape, the bioinformatics method was used to analyze the chromosomal location, molecular evolution, conservatism of the precursor sequence, promoter and target gene of the members of the miR169 gene family. The results showed that miR169 gene family members were distributed in 9 chromosomes. Evolution analysis showed that these genes were divided into two groups. The precursor sequence was highly conserved at the position where the mature miRNA was formed. There were 13 main elements in the upstream promoter of the miR169 genes, endosperm expression element, anaerobic stress component, thermal response element and MBS had the most quantities. miR169 gene family had a total of 16 target genes, most of which belong to the NF-YA gene family. The results laid a good foundation for further research on the function of miR169 gene family in oilseed rape.
