TL;DR: Analysis of the ultrastructure of chloroplasts indicated that salinity induced destruction of the chloroplast envelope and increased the number of plastoglobuli with aberrations in thylakoid membranes, but application of Spm counteracted the adverse effects of salinity on the structure of the photosynthetic apparatus.

TL;DR: Under heat stress, exogenous melatonin increased endogenous NO content along with nitrate reductase- and NO synthase-related activities, and expression of their related genes were also elevated, and melatonin-pretreated seedlings had further increased PAs levels and upregulated transcript abundance, which coincided with suppression of catabolic-related genes expression.

TL;DR: PAs in chloroplasts play crucial roles in protecting the thylakoid membranes against the deleterious influences of salt stress, and the present results point to the probability that the salt-induced dysfunction of photosynthesis is largely attributable to the loss of PAs.

TL;DR: The findings deciphered the potential functions of melatonin in alleviating Ni-induced phytotoxicity in tomato through boosting the biomass production, photosynthesis, nutrient uptake, redox balance, and secondary metabolism.

TL;DR: The results suggest that EBR could alleviate the combined stress-induced harmful effects on photosynthesis and nitrogen metabolism, thus leading to improved plant growth.
