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 suggest that pathogens induce nitrosative stress in susceptible cultivars and the increase of tyrosine nitration of proteins can be considered a general biological marker of nitrosive stress in plants under biotic conditions.

TL;DR: The results suggest that Tyr nitration occurs in plant tissues under physiological conditions that could constitute an important process of protein regulation in such a way that, when it is overproduced in adverse circumstances, it can be used as a marker of nitrosative stress.

TL;DR: It is proposed that mechanical wounding triggers the accumulation of SNOs, specifically GSNO, due to a down-regulation of GSNOR activity, while NO2-Tyr increases, and a process of nitrosative stress is induced in sunflower seedlings and SNOs constitute a new wound signal in plants.

TL;DR: Results suggest that HT augments SNOs, which appear to mediate protein tyrosine nitration, inhibiting FNR, which is involved in the photosynthesis process.
