DROUGHT HYPERSENSITIVE negatively regulates cuticular wax biosynthesis by promoting the degradation of transcription factor ROC4 in rice

, , ,
Wax covering the outer surface of the shoot (epicuticular wax) is crucial in the ability of the plant to conserve water. Wang et al. identified a drought hypersensitive plant that overexpresses an E3 ubiquitin ligase which they named DROUGHT HYPERSENSITIVE. In these overexpression plants, there was a…
