OsHDA716-OsbZIP46 regulates cold responses
The Plant Cell: In a NutshellSun et al. demonstrate that histone deacetylase OsHDA716 represses rice chilling tolerance not only by functioning as an epigenetic regulator but also by deacetylating OsbZIP46 to reduce its transactivation function and protein stability.
