Review: Hydrogen sulphide - an emerging regulator of plant defence signalling

A growing body of evidence indicates potential role of H2S in plant defence, particularly against bacterial and fungal pathogens. Recent studies suggested that the gaseous signalling molecule participates in plant defence potentially by
- regulating glutathione metabolism,
- inducing expression of pathogenesis-related (PR) and other defence-related genes,
- modulating enzyme activity through post-translational modifications, and
- interacting with phytohormones such as jasmonic acid, ethylene and auxin.
The authors Choudhary, Singh, Khatri, and Gupta discuss the biosynthesis, metabolism and interaction of H2S with phytohormones, and highlight evidence gathered so far to support the emerging roles of H2S in plant defence against invading pathogens.
