This book describes the three gasotransmitters nitric oxide (NO), hydrogen sulphide (H2S) and carbon monoxide (CO) and their function as intracellular signalling molecules in plants.

Carbon Monoxide: a Ubiquitous Gaseous Signaling Molecule in Plants.- Nitric oxide emission and uptake by higher plants.- Modulation of nitric oxide levels by phytoglobin affects developmental and stress responses in plants.- Growth promoting effects of NOx fumigation and phytoglobins.- Nitric oxide (NO), a central gasotransmitter at early plant developmental stages.- Nitric oxide acts at the crossroad between auxin and reactive oxygen species determining the outcome of root growth and development.- Nitric oxide: a multi-task player in plant-microorganism symbioses.- Emerging functions of nitric oxide in plant immunity.- Protein denitrosylation in plant biology.- Functions and metabolism of S-nitrosothiols and S-nitrosylation of proteins in plants: the role of S-nitrosoglutathione reductase.- Hydrogensulfide in plants.- Regulation of autophagy by hydrogen sulfide.- Deciphering the dialogue between NO and H2S in guard cells.- New features of the NO/H2S crosstalk: a chemical basis.
