A mode of HDA 6 and HDA 19 function in the regulation of gene expression in ABA and abiotic stress response. Arabidopsis AtERF4 and AtERF7 bind to the promoters of the target genes and recruits AtSin3, a co-repressor, which in turn may interact with histone deacetylases, HDA6 and HDA19. AtERF4 and AtERF7 may therefore repress gene expression through chromatin modification mediated by histone deacetylation. The activity of AtERF4 and AtERF7 can also be affected by the protein kinase PKS3.
