Histone Deacetylase CpHDA3 Is Functionally Associated with CpERF9 in Suppression of CpPME1/2 and CpPG5 Genes during Papaya Fruit Ripening

were increased during fruit ripening. Taken together, these results suggested that CpERF9 recruits CpHDA3 to form a histone deacetylase repressor complex to mediate pectin methylesterase and polygalacturonase genes expression during papaya fruit ripening and softening.
