Persulfidation in plants: the new phosphorylation?
31 October 2017
One in 20 proteins in Arabidopsis is persulfidated: this we now know. Evidence of the role played by hydrogen sulfide signalling in plants has been building in recent years, and it is new methodology which has revealed the likely extent. Indeed, the study by Angeles Aroca and colleagues in Journal of Experimental Botany goes further in showing an association with a wide range of biological functions. See also the separate Insight article for further reflection on the implications of this ground-breaking research, including the questions it opens up from our knowledge of animal systems.
