Nitric oxide (NO) is perfectly suited for duties as a redox signalling molecule. A key route for NO
bioactivity occurs via protein S-nitrosation, the addition of a NO moiety to a protein cysteine
(Cys) thiol (-SH) to form a S-nitrosothiol (SNO). This process is thought to underpin a myriad of
cellular processes in plants linked to development, environmental responses and immune function.
Here we collate emerging evidence showing that NO bioactivity regulates a growing number of
diverse post-translational modifications (PTMs) including SUMOylation, phosphorylation,
persulfidation and acetylation. We provide examples of how NO orchestrates these processes to
mediate plant adaptation to a variety of cellular cues.
