The authors found that HDA9 acts in complex with a SANT domain-containing protein POWERDRESS (PWR) and transcription factor WRKY53. Genome-wide profiling of HDA9 occupancy reveals that HDA9 directly binds to the promoters of key negative regulators of senescence and this association requires PWR.

HDA9 might be a novel chromatin protein that negatively regulates plant sensitivity to salt and drought stresses.
Title: Histone deacetylase HDA9 negatively regulates salt and drought stress responsiveness in Arabidopsis.

HDA9 prevents precocious flowering under SD conditions by curbing the hyperactivation of AGL19, an upstream activator of FT, through resetting the local chromatin environment.

HDA9 negatively influences germination and is involved in the suppression of seedling traits in dry seeds, probably by transcriptional repression via histone deacetylation.

The data indicate thatHDA9 represses flowering by repressing AGL19 gene expressionindependently of CONSTANS or FLC pathways.
