Histone deacetylase AtSRT2 regulates salt tolerance during seed germination via repression of vesicle-associated membrane protein 714 (VAMP714) in Arabidopsis.

Salt tolerance during seed germination is essential for seedling establishment under salt stress. Sirtuin-like proteins, NAD -dependent histone deacetylases, are involved in plant responses to abiotic stresses; however, the regulatory mechanism remains unknown. We elucidated the mechanism underlying AtSRT2 (a sirtuin-like protein)-mediated regulation of salt tolerance during seed germination in Arabidopsis.
