Summary

Plants produce a variety of reactive oxygen, nitrogen, and sulfur either under physiological conditions or when are threatened. Among them, considerable attention has been directed to hydrogen peroxide (H2O2), nitric oxide (NO), and most recently to hydrogen sulfide (H2S) particularly with respect to their involvement in plant response to abiotic stresses. This chapter highlights the main sources of these signaling molecules, the control of their homeostasis, the interaction among them, and biochemical events subsequently triggered in plant cells in response to several abiotic stress. Herein, it is intended to show the way H2O2, NO, and H2S tailor to fancily suit plants against environmental adverse conditions.
