“…Also, the beneficial effects of foliar applications of The results showed that SA application alone increased the growth, fresh and dry weight of the shoots and roots. In agreement with the reports of Kováčik, Gruz et al (2009) in Matricaria chamomilla plants, and Wang et al (2009) in Zea mays, the findings of this study indicated that a substantial improvement in root fresh and dry weights was noticed due to exogenously applied SA under 500 µM concentrations of Ni. Also, consistent with the results of on Matricaria chamomilla, the present study revealed that non-significant changes were observed in the chlorophylls and carotenoid contents of M. officinalis treated plants with different concentrations of Ni, except at 500 µM, as compared to the control.…”

“…It has been reported in many studies that exogenous application of SA could mitigate toxicity effect of heavy metals on photosynthetic pigments contents and net photosynthetic rate (Krantev et al 2008;Popova et al 2009;Wang et al 2009;Kazemi et al 2010;Guo et al 2013;Saidi et al 2013). The evidence suggests that the beneficial effects of SA on photosynthetic apparatus might be due to its direct effects as a potent antioxidant to scavenge heavy metal-induced reactive oxygen species (Popova et al 2009;Ahmad et al 2011).…”

“…However, some studies have shown that SA might indirectly improve resistance of plants to heavy metal stress through up-regulating the capacity of antioxidant defense system (enzymatic or non-enzymatic antioxidants) in chloroplasts (Krantev et al 2008;Shi & Zhu, 2008;Popova et al 2009;Wang et al 2009;Yusuf et al 2012;Guo et al 2013;Idrees et al 2013;Saidi et al 2013). It has also been shown that exposure to SA could reduce the inhibitory effects of heavy metals on the absorption and transport of nutrients which are essential for chlorophylls and carotenoids biosynthesis in the chloroplasts (Saidi et al 2013).…”

The present study investigated the mediatory effects of salicylic acid (SA) in alleviating nickel (Ni) toxicity in Melissa officinalis L. One-month old plants were exposed to different levels of Ni and SA concentrations in sand culture under greenhouse conditions. Excess Ni significantly inhibited the growth indices, and dramatically increased accumulation of Ni in the leaves and roots. Exogenously SA applications (1.0 mM) led to a substantial improvement in the shoot and root fresh and dry weights. Foliar application of SA mitigated the deleterious effects of Ni and decreased its transport to the shoots. The results showed a significant loss in chlorophylls and carotenoids contents only at 500µM of Ni. The impact of SA was not significant in terms of chlorophylls contents, while carotenoids contents of the Ni-stressed Downloaded by [University of Bath] at 08:50 29 June 2016 plants were significantly affected by SA. Exposure to Ni did not modify proline accumulation. Hydrogen peroxide accumulation was observed under Ni stress, while lipid peroxidation significantly decreased at the same conditions. Application of SA caused a significant decrease in electrolyte leakage of Ni-stressed plants. Due to the high potential for Ni accumulation in the roots and TF values lower than 1, M. officinalis could be introduced as an excluder medicinal plant.

“…In plant cell cultures, SA and MJ are reported to enhance secondary metabolite production (Sudha and Ravishankar 2003) through influence of transcription of some nuclear genes (Stockigt et al 1995). Chloroplastidic antioxidant capacity is increased by SA through increase in antioxidant enzymes and b-carotene in maize (Wang et al 2009). Since astaxanthin is reported to be accumulated under stress conditions as a photoprotective mechanism, and MJ and SA are defense signaling molecules, effect of these compounds on carotenogenesis and antioxidant systems of this organism is studied.…”

The influence of phytohormones, salicylic acid (SA) and methyl jasmonate (MJ) on the antioxidant systems in Haematococcus pluvialis was investigated. Both SA and MJ at 500 lM concentration reduced the growth of alga with salicylic acid, having more pronounced effect. Carotenoid and chlorophyll contents were decreased by SA and increased by MJ. Salicylic acid (100 lM) increased astaxanthin content to 6.8-fold under low light (30 lmol m -2 s -1 ), while MJ (10 lM) showed marginal increase in astaxanthin. Salicylic acid (500 lM) increased superoxide dismutase activity to 4.5-and 3.3-fold and ascorbate peroxidase (APX) activity to 15.5-and 7.1-fold under low and high light, respectively. Methyl jasmonate increased catalase activity (1.4-fold) under high light and APX activity (5.4-fold) under low light. Different mechanism of oxidative stress induced antioxidant production may be the plausible reason for this varied response for salicylic acid and methyl jasmonate. Higher concentrations of SA and MJ inhibited astaxanthin accumulation by different mechanisms either by scavenging the free radicals or by increasing primary carotenoids production. At lower concentrations, these phytohormones could be used for elicitation of secondary carotenoid production.

Previous studies have shown that salicylates can change the ion permeability of root cells. Therefore the possible effects of exogenous salicylate application on lead (Pb) and copper (Cu) accumulation and its protective role against DNA damage due to metal exposure in Lemna gibba were studied. L. gibba was exposed to 5, 10, and 25 μM Pb and Cu for six days in the presence and absence of sodium salicylate (SA) (0.1, 0.5, and 1 mM). At all concentrations tested, SA application decreased Pb accumulation. On the other hand, application of 0.5 mM SA increased Cu accumulation. SA did not reduce DNA damage resulting from Pb and Cu toxicity. In summary, SA may be useful for reducing Pb accumulation, and application of SA at 0.5 mM may be useful for the phytoextraction of Cu
