Histone deacetylases (HDAC) are important in plant gene expression.

Annotated Information

Function

• Down-regulation of HDA703 by amiRNA reduced rice peduncle elongation and fertility,while inactivation of a closely related homolog HDA710 by RNAi affected vegetative growth.
• HDA704 RNAi altered plant height and flag leaf morphology.
• Down-regulation of HDT702 led to the production of narrowed leaves and stems.
