This review considers the action of nitric oxide (NO) as a signaling molecule of plant cells, the effects of which can be modulated in crop production practice through the use of nitric oxide donors.The current understanding of nitric oxide synthesis in plants is briefly described.The characterization of synthesized and natural compounds that can be nitric oxide donors is given.The main molecular mechanisms of nitric oxide action in plant cells are characterized: post-translational modification of proteins under the action of NO, its influence on the content of other cellular mediators, in particular, reactive oxygen species and calcium ions.Considerable attention is paid to the functional interaction of nitric oxide with individual phytohormones and new groups of physiologically active substances of plants.Modern ideas on the mechanisms of nitric oxide action on seed germination and plant resistance to adverse abiotic factors are presented.Data on the effects of priming seeds with nitric oxide donors on their germination under optimal and stress conditions are discussed.
