“…MeJA at 100 μM or higher concentration repressed germination (Kobayashi et al, 2010) and plant growth (Jubany-Marí et al, 2010), Rubisco genes, chlorophyll a / b -binding protein, light harvesting complex II (Jung et al, 2007). In contrast, lower MeJA concentration mostly stimulated plant growth, lateral root initiation, dry matter accumulation, photosynthetic pigment levels, and net photosynthetic rate (Tung et al, 1996; Mabood et al, 2006; Piotrowska et al, 2010; Wu et al, 2012). Our study showed that 10 μM MeJA improved chlorophyll content, gas exchange parameters and Rubisco activity under Cd stress.…”

Methyl Jasmonate Alleviates Cadmium-Induced Photosynthetic Damages through Increased S-Assimilation and Glutathione Production in Mustard

The effect of methyl jasmonate (MeJA) in mitigation of 50 μM cadmium (Cd) toxicity on structure and function of photosynthetic apparatus in presence or absence of 1.0 mM SO42– was investigated in mustard (Brassica juncea L. cv. Ro Agro 4001) at 30 days after sowing. Plants exhibited increased oxidative stress, impaired photosynthetic function when grown with Cd, but MeJA in presence of sulfur (S) more prominently ameliorated Cd effects through increased S-assimilation and production of reduced glutathione (GSH) and promoted photosynthetic functions. The transmission electron microscopy showed that MeJA protected chloroplast structure against Cd-toxicity. The use of GSH biosynthetic inhibitor, buthionine sulfoximine (BSO) substantiated the findings that ameliorating effect of MeJA was through GSH production. MeJA could not alleviate Cd effects when BSO was used due to unavailability of GSH even with the input of S. The study shows that MeJA regulates S-assimilation and GSH production for protection of structure and function of photosynthetic apparatus in mustard plants under Cd stress.

“…and plant growth (Jubany-Marí et al 2010;Kobayashi et al 2010) and genes involved in photosynthesis, such as ribulose bisphosphate carboxylase/oxygenase (Rubisco), chlorophyll a/b-binding protein, light harvesting complex II, and early light-induced proteins, were down-regulated (Jung et al 2007). At a concentration of 50 lM or lower, MJ mostly, but not always (Noir et al 2013), stimulated plant growth, lateral root initiation and growth, dry matter accumulation, biomass production, photosynthetic pigment levels, and elevation of the net photosynthetic rate (Tung et al 1996;Mabood et al 2006;Piotrowska et al 2010;Wu et al 2012). However, the role of MJ in protecting plants from various abiotic stresses has been controversial.…”

The effect of methyl jasmonate on selected physiological parameters of copper-treated Phaseolus coccineus plants

2015

Phaseolus coccineus plants in the early growth stage were preincubated with 10 -5 M methyl jasmonate (MJ) for 1 or 24 h and subsequently transferred to a Hoagland solution or treated with 50 or 100 lM copper (Cu). After 6-day exposure to the metal, plant growth, relative water content, electrolyte leakage, the content of Cu and photosynthetic pigments, and chlorophyll fluorescence parameters were assayed. Generally, under Cu excess, MJ did not modulate growth parameters such as leaf area, root growth, shoot and root fresh weight, and the shoot/root fresh weight ratio. The content of chlorophyll a, b, and carotenoids increased with the increasing Cu content in the leaves. However, a correlation between the reduction of the leaf area and the lower content of the three photosynthetic pigments for 24-h MJ ? 100-lM Cu treatment compared with metal alone was noted. The decrease in the Cu concentration was MJ-dependent only after 1-h MJ ? 50-lM Cu treatment in leaves and after 24-h MJ ? 100-lM Cu treatment in roots. Chlorophyll fluorescence was a weak indicator of the effect induced by MJ in Cu excess, and the most spectacular increase was observed for 1-h and 24-h MJ ? 50 lM Cu in the LNU and for 1-h MJ ? 50 lM Cu in the NPQ parameter. These results suggested a lack of a clear pattern for MJ altering the Cu stress in the runner bean plants. The most important finding was that photosynthesis seemed to be quite resistant to Cu stress and slight modifications in chlorophyll fluorescence were accompanied by significant changes in growth parameters, photosynthetic pigment content, and metal content in the plant. The results obtained may have been strongly related to the plant growth stage, as the measured parameters transform greatly during plant growth and development.
