As a dominant mangrove species, Kandelia obovata is distributed in an intertidal marsh with an active H2S release. Whether H2S participates in the salt tolerance of mangrove plants is still ambiguous, although increasing evidence has demonstrated that H2S functions in plant responses to multiple abiotic stresses. In this study, NaHS was used as an...

Background and aim Calcium oxalate (CaOx) is a common biomineral found in the plant kingdom. Crystals of CaOx occur in different plant tissues, such as leaves and stems. However, little is known about the biosynthesis of CaOx in oxalate-accumulating plants. Moreover, the literature on genes related to CaOx formation under high-calcium environment i...
