Genome-wide identification and expression analysis of JmjC domain-containing genes in grape under MTA treatment.

Histone demethylases containing the JmjC domain play an extremely important role in maintaining the homeostasis of histone methylation and are closely related to plant growth and development. Currently, the JmjC domain-containing proteins have been reported in many species; however, they have not been systematically studied in grapes. In this paper, 21 VviJMJ gene family members were identified from the whole grape genome, and the VviJMJ genes were classified into five subfamilies: KDM3, KDM4, KDM5, JMJD6, and JMJ-only based on the phylogenetic relationship and structural features of Arabidopsis and grape.
