“…Supplementation of different concentrations of JA in growing medium considerably enhanced activities of all scavenging enzymes signified the ameliorative properties of JA to decrease the damaging effect of metal stress on growing seedlings. Keramat et al (2010) reported similar results of ameliorative effect of one form of JA as Me-JA on antioxidant mechanism to repair the damages initiated by ROS under metal stress.…”

Jasmonic acid (JA) is a very young candidate of plant growth regulators which is being explored for various antistress properties. Present study deals with the hypothesis that JA can modulate antioxidant mechanism of higher plants with tight regulation of biomembrane peroxidation, making plants tolerant to toxic Ni 2+ stress may involve two aspects, either denovo synthesis level regulation of AsA or recycling of AsA from an oxidized form. Improvement in total protein content showed the uplift modulation of transcriptional machinery by JA which was also maintained under Ni 2+ stress. Photosynthetic pigments as total chl, chl a and b showed inhibition in presence of Ni 2+ stress which was not found much effective under JA supplementation as compared to control. Present findings revealed that although JA was not helpful for protection of photosynthetic pigments but it modulates the other machinery of plants significantly including various antioxidants positively, while tightly inhibiting stress related processes responsible for lipid peroxidation to make plants tolerant to Ni 2+ stress.

“…This was associated with the activation of antioxidant enzymes and recovery of photosynthetic efficiency. Keramat et al (2010) have also reported that MeJA at 0.01 mM was more effective in reducing the damages of Cd stress on shoot dry weight and total chlorophyll content in G. max . Recently, it has been shown that S and Se increased photosynthesis via increase in the allocation of N and S to Rubisco in B. juncea and Triticum aestivum crops (Fatma et al, 2014; Khan et al, 2015).…”

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

et al. 2016

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.

“…For example, Cd induced the expression of JA synthesis and JA‐response genes (Cabot et al ; Keunen et al ), and a biphasic‐modal accumulation of JA was observed in the mature leaves of Arabidopsis (Maksymiec et al ). Exogenous JA increased the activity of classic antioxidant enzymes, reduced Cd‐induced ROS levels and alleviated Cd‐mediated growth inhibition in soybean or Solanum nigrum , indicating that JA is an important trigger to the antioxidant response against Cd toxicity (Keramat et al ; Noriega et al ; Yan et al ). However, contrasting evidence has indicated that inhibition of the JA synthesis and signaling pathways decreased Cd‐induced ROS and alleviated Cd‐mediated inhibition of root and leaf growth in Arabidopsis , bean or onion (Maksymiec and Krupa ; Maksymiec et al ; Maksymiec ).…”

Jasmonic acid (JA) is thought to be involved in plant responses to cadmium (Cd) stress, but the underlying molecular mechanisms are poorly understood. Here, we show that Cd treatment rapidly induces the expression of genes promoting endogenous JA synthesis, and subsequently increases the JA concentration in Arabidopsis roots. Furthermore, exogenous methyl jasmonate (MeJA) alleviates Cd‐generated chlorosis of new leaves by decreasing the Cd concentration in root cell sap and shoot, and decreasing the expression of the AtIRT1, AtHMA2 and AtHMA4 genes promoting Cd uptake and long‐distance translocation, respectively. In contrast, mutation of a key JA synthesis gene, AtAOS, greatly enhances the expression of AtIRT1, AtHMA2 and AtHMA4, increases Cd concentration in both roots and shoots, and confers increased sensitivity to Cd. Exogenous MeJA recovers the enhanced Cd‐sensitivity of the ataos mutant, but not of atcoi1, a JA receptor mutant. In addition, exogenous MeJA reduces NO levels in Cd‐stressed Arabidopsis root tips. Taken together, our results suggest that Cd‐induced JA acts via the JA signaling pathway and its effects on NO levels to positively restrict Cd accumulation and alleviates Cd toxicity in Arabidopsis via suppression of the expression of genes promoting Cd uptake and long‐distance translocation.
