Analysis of WRKY Transcription Factor Ⅱc Subfamily in Maize and Its Expression Profile under Drought
The members of the WRKY Ⅱc subfamily of maize were identified by bioinformatics methods,and their physicochemical properties,chromosomal location,gene structures,protein conserved domains,cis-acting elements in the promoters were comprehensively analyzed.The expression of ZmWRKY Ⅱc subfamily in different tissue parts and different growth and development stages under drought treatment were analyzed by using the published RNA-seq data.Furthermore,the interaction network of ZmWRKY Ⅱc proteins was constructed.The results showed that the WRKY Ⅱc subfamily of maize had 25 members,they were relatively conserved in evolution and could participate in the regulation of drought stress responses in different tissues and stages of growth and development.They may also interact with MYB,bHLH transcription factors and auxin regulators to resist drought stress.
