To understand affected genes by HDA19 and HDA5/14/15/18 under salinity stress conditions, hda19 and hda5/14/15/18 mutants and control (Col-0) plants were analyzed under normal and salinity stress conditions using Arabidopsis custom microarrays (GEO array platform: GPL19830). Overall design: Microarray analysis was conducted using hda19, hda5/14/15/18, and Col-0 plants subjected to non-stress and 125 mM NaCl salt-stress condition for 2 h.
