摘      要：The Arabidopsis thaliana RPD3-type histone deacetylases have been known to form conserved SIN3-type histone deacetylase complexes,but whether they form other types of complexes is ***,we perform affinity purification followed by mass spectrometry and demonstrate that the Arabidopsis RPD3-type histone deacetylases HDA6 and HDA19 interact with several previously uncharacterized proteins,thereby forming three types of plant-specific histone deacetylase complexes,which we named SANT,ESANT,and ***-seq indicates that the newly identified components function together with HDA6 and HDA19 and coregulate the expression of a number of ***6 and HDA19 were previously thought to repress gene transcription by histone *** find that the histone deacetylase complexes can repress gene expression via both histone deacetylation-dependent and-independent *** the mutants of histone deacetylase complexes,the expression of a number of stressinduced genes is up-regulated,and several mutants of the histone deacetylase complexes show severe retardation in *** that growth retardation is thought to be a trade-off for an increase in stress tolerance,we infer that the histone deacetylase complexes identified in this study prevent overexpression of stress-induced genes and thereby ensure normal growth of plants under nonstress conditions.
