TL;DR: The presence of NOS in peroxisomes suggests that these oxidative organelles are a cellular source of nitric oxide (NO) and implies new roles for peroxISomes in the cellular signal transduction mechanisms.

TL;DR: The cellular and subcellular localization of endogenous nitric oxide (NO˙) in leaves from young and senescent pea plants was studied and it is proposed that peroxisomal NO˙ could be involved in the process of senescence of pea leaves.

TL;DR: It is shown that in olive leaves salinity induces nitrosative stress, and vascular tissues could play an important role in the redistribution of NO‐derived molecules during nitrosatives stress.

TL;DR: The results obtained suggest that low and high temperature, continuous light and high light intensity are abiotic stress conditions that can induce nitrosative stress in pea plants.

TL;DR: These loci of NO generation and accumulation suggest novel functions for NO in these cell types, and the arginine-dependent NOS activity was constitutive and sensitive to aminoguanidine, a well-known irreversible inhibitor of animal NOS, and this NOSActivity was differentially modulated depending on the plant organ and seedling developmental stage.
