    Recommendations on terminology and experimental best practice associated with plant nitric oxide research
    (John Wiley & Sons, 2020) Gupta, Kapuganti Jagadis; Hancock, John T.; Petrivalsky, Marek; Kolbert, Zsuzsanna; Lindermayr, Christian; Durner, Jorg; Barroso, Juan B.; Palma, José M.; Brouquisse, Renaud; Wendehenne, David; Corpas, Francisco J.; Loake, Gary J.
    Nitric oxide (NO) emerged as a key signal molecule in plants. During the last two decades impressive progress has been made in plant NO research. This small, redox‐active molecule is now known to play an important role in plant immunity, stress responses, environmental interactions, plant growth and development. To more accurately and robustly establish the full spectrum of NO bioactivity in plants, it will be essential to apply methodological best practice. In addition, there are some instances of conflicting nomenclature within the field, which would benefit from standardisation. In this context, we attempt to provide some helpful guidance for best practice associated with NO research and also suggestions for the cognate terminology.

    Regulating the regulator: nitric oxide control of post-translational modifications
    (John Wiley & Sons, Inc., 2020) Gupta, Kapuganti Jagadis; Kolbert, Zsuzsanna; Durner, Jorg; Lindermayr, Christian; Corpas, Francisco J.; Brouquisse, Renaud; Barroso, Juan B.; Saima, Umbreen; Palma, José M; Hancock, John T.; Petrivalsky, Marek; Wendehenne, David; Loake, Gary J.
    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.
