“…Hydroperoxides formed from lipids may have been preferentially converted at the higher Cd concentration into more stable compounds, including jasmonic acid, as was supposed by Rucinska and Gwózdz (2005) and supported by the findings of Maksymiec et al (2005), which indicated rapid accumulation of jasmonic acid after heavy metal stress. The lack of significant changes in the membrane permeability additionally confirms this conclusion.…”

Maize seedlings grown in a nutrient solution were treated with Cd (50, 100 lM) or Cu (50, 100 lM). Roots and separated leaf sections (from the youngest--basal, through the middle--mature, to the oldest--apical) were analysed. Shoot and root fresh weight, and root net growth rates were reduced significantly after Cu application in comparison to Cd. Copper (50, 100 lM) and cadmium (100 lM) decreased the sum of chlorophyll and total carotenoid pools mostly in mature and old leaf sections. The concentration of Cu and Cd increased in the old and mature leaf sections. Analysis of organic acids showed that both metals differently influenced the lowmolecular-weight organic acids (LMWOAs) content in maize leaf sections. In mature sections, the excess Cu increased the succinate and tartrate contents, whereas in the young ones mainly the tartrate level was elevated. Cadmium elevated citrate accumulation in mature and old sections, compared to the control plants. Malate, the main LMWOA in maize leaves, increased only after addition of 100 lM of Cd (mature and old sections) or 50 lM of Cu (old sections). Analysis of LMWOAs in roots showed that the excess of Cd or Cu induced higher accumulation of tartrate and malate and, additionally, copper increased the citrate content.

“…Furthermore, the level of JA was also age-dependent, i.e. higher for younger than older leaves (Maksymiec et al 2005), which suggests that JA may be involved in the cellular responses at the early stage of metal stress (Yan et al 2013), and this may be the cause of the lower susceptibility to MJ detected in the early growth stage of runner bean plants. Besides, Maksymiec and Krupa (2002) reported an MJ dose-dependent influence on chlorophyll fluorescence parameters measured under Cu or Cd stress; MJ only up to 10 lM provided protection and lost its positive effect at higher concentrations.…”

“…Even short exposition to the excess of heavy metals, such as Cu, gives visual and physiological changes in plants (Maksymiec andKrupa 2002, 2007), which suggests contribution of signaling pathways based on MJ (Maksymiec et al 2005;Maksymiec 2007).…”

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.

“…However, in Cd-treated A. thaliana plants their level dependend on metal concentration (Skórzyñska-Polit et al 2004a). In A. thaliana and P. coccineus exposed to Cd or Cu, an elevated level of jasmonic acid was found (Maksymiec et al 2005). This means that linolenoic acid was a main substrate for LOX and such a signal particle is formed in response to heavy metal stress.…”

Lipid peroxidation, which is a natural and essential process, can occur in a non-enzymatic and/or enzymatic way in plant cells. Some of its products have cytotoxic effects on cells, but others function as plant effectors. The lipid peroxidation in plants exposed to heavy metal stress depends on the metal, plant organ, plant species and its genotype.KEY WORDS: heavy metal stress, lipid peroxidation, lipoxygenase.
