Possible Interaction: Melatonin and Proline

“Moreover, melatonin enhanced the capacity of osmotic adjustment by increasing the accumulation of osmolytes (betaine, proline , and soluble sugar).”

“ MT also reduces the osmotic pressure by reducing the salt-induced accumulation of Na + and increasing the contents of K + and proline.”

“In addition, melatonin counteracted the drought-induced increase in proline and sugar content.”

“The melatonin also alleviated Cr-induced chlorophyll and carotenoids inhibition, improved relative water content, and markedly lowered proline and MDA content in shoots.”

“The proline and phenol contents decreased in the exogenous application of LA + MT treatments more than individual LA or MT treatments under the salinity stress.”

“ Melatonin stimulated the accumulation of proline , soluble sugars and abscisic acid, which were positively correlated with a better preservation of leaf water status in drought-stressed plants.”

“In addition, MLT treatment resulted in enhanced proline accumulation, which was likely a consequence of the increased activities of ornithine-δ-aminotransferase (OAT) and Δ1-pyrroline-5-carboxylate synthase (P5CS) and the suppressed activity of proline dehydrogenase (PDH).”

“ Melatonin supplementation under Al and Cd stress, increased the superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX), proline , chlorophyll, anthocyanin contents and photosynthetic rate.”

“The accumulation of compatible solutes such as total soluble sugars and proline was also triggered by melatonin.”

“ Melatonin pretreatment increased the antioxidant enzyme activities and root vigor, and decreased the proline and malondialdehyde (MDA) contents in the roots of copper-stressed melon seedlings.”
