Minghui Du, Peng Zhang, Ge Wang, Xinyi Zhang, more

Plant, Cell & Environment > 45 > 10 > 2923 - 2942

Signalling roles of hydrogen sulphide (H₂S) in stress biology are widely reported but not sufficiently established to urge its use in agronomic practice. Our lack of quantitative understanding of the metabolic rewiring in H₂S signalling makes it difficult to elucidate its functions in stress tolerance on the biochemical level. Here, Malus hupehensis Rehd. var. pingyiensis seedlings were first treated...
