Role of Exogenous Nitric Oxide in Protecting Plants against Abiotic Stresses

The continuously changing environment has led to devastating effects on the normal growth and development of plants. This necessitates understanding different components that can be involved in alleviating these effects. In last two decades, nitric oxide (NO) been largely focused as a molecule whose endogenous production exogenous supply lead several molecular physiological changes plants under stressed conditions. Although its role signaling discussed, function dealing with contemporary abiotic stress conditions remains comparatively less explored. There is growing evidence NO plays critical many processes; however, there debate about exact mechanism(s) through which lessens external supply. this review, we discuss studies were observing effect stresses including heavy metal stress, element deficiency or toxicity salt drought ultraviolet radiation waterlogging chilling stress. Though positive have discussed brief sections, focus review plant grown stresses. Deciphering underlying mechanism treatment may open up new ideas suggest successful application agricultural regions reduce damaging influences
