Abstract
Nitric oxide (NO) and hydrogen sulfide (H
2S) are two molecules that share signaling properties in plant and
animal cells. NO and H
2S originate two families of derived molecules designated reactive nitrogen and sulfur species (RNS
and RSS, respectively). These molecules are responsible for certain protein regulatory processes through posttranslational
modifications (PTMs), being the most remarkable S-nitrosation and persulfidation, which affect the thiol group of
cysteine residues. NO and H
2S can also exert regulatory functions due to their interaction through the iron present in
proteins that contain heme groups or iron-sulfur clusters, as reported mainly in animal cells. However, the available
information in plant cells is still very limited thus far. In higher plants, NO and H
2S are involved in a myriad of
physiological events from seed germination to fruit ripening, but also the mechanism of response to biotic and abiotic
stress conditions. This viewpoint manuscript highlights the functional regulatory parallelism of these two molecules
which also interact with the metabolism of reactive oxygen species (ROS) in plant cells.
