Abstract Plants are exposed to environmental stress, in natural and agricultural conditions.Nitric oxide
(NO), a small gaseous molecule which plays important roles in plants, has been involved in many physiological
processes, and emerged as an important endogenous signaling molecule in the adaptation of plants to biotic and
abiotic stress. NO is produced from a variety of enzymatic and non enzymatic sources, which are not yet fully
understood. Also, NO and reactive nitrogen species (RNS) can produce posttranslational modifications affecting
protein function. Nitrate reductase, a key enzyme in the nitrogen metabolism, is a proposed source of NO More >
