WebHistone Deacetylation is the covalent post-translational enzymatic removal of acetyl group(s) from a histone protein. By exposing cationic sites on the protein that promote ionic interaction with the negatively charged DNA backbone, Histone Deacetylation induces DNA condensation and regulates genetic functions, such as transcription. Web7 feb. 2024 · In this study, we identified cassava bacterial blight (CBB) responsive histone deacetylase 9 (HDA9), which negatively regulated disease resistance to CBB by reducing melatonin content. In addition, exogenous melatonin alleviated disease sensitivity of MeHDA9 overexpressed plants to CBB.
