    A forty year journey: The generation and roles of NO in plants
    (Elsevier B.V., 2019) Kolbert, Zs; Barroso, J.B.; Brouquisse, R.; Corpas, F.J.; Gupta, Kapuganti Jagadis; Lindermayr, C.; Loake, G.J.; Palma, J.M.; Petřivalský, M.; Wendehenne, D.; Hancock, J.T.
    In this year there is the 40th anniversary of the first publication of plant nitric oxide (NO) emission by Lowell Klepper. In the decades since then numerous milestone discoveries have revealed that NO is a multifunctional molecule in plant cells regulating both plant development and stress responses. Apropos of the anniversary, these authors aim to review and discuss the developments of past concepts in plant NO research related to NO metabolism, NO signaling, NO's action in plant growth and in stress responses and NO's interactions with other reactive compounds. Despite the long-lasting research efforts and the accumulating experimental evidences numerous questions are still needed to be answered, thus future challenges and research directions have also been drawn up.

    The interactions of nitric oxide with intracellular redox status and the influence of molecular hydrogen
    (Elsevier B.V., 2026) Hancock, J T; Corpas, F J; Kolbert, Zs; Silveira, N M; Gupta, Kapuganti Jagadis
    Nitric oxide (NO) has a wide range of effects in both animals and plants. It accumulates in cells, especially during stress responses, leading to signalling events. Many of these downstream signals rely on S-nitrosation of proteins, or nitration of proteins, but NO also interacts with a range of other cellular components, including lipids, but also other small reactive compounds. A well-known example of such a NO reaction is with the reactive oxygen species (ROS) superoxide, producing peroxynitrite. One characteristic of cells which is crucial to the control of cellular activity is the intracellular redox state, and this is maintained by compounds such as glutathione (GSH), but also impinged upon by ROS, reactive sulphur compounds such as hydrogen sulfide (H2S), and potentially by hydrogen gas (H2). Into this mix is NO, and here the potential influence of NO on cellular redox is discussed.
