“…Carotenoids decreased significantly by 28 % only 24 h after UV-c exposure, then tended to increase and almost reached the respective control value at the last measurement point. together with the nucleic acids, aminoacids, proteins, and lipids, leaf pigments are also considered as a target site for UV light (12), and our results are in accordance with the decrease of leaf pigments reported in other studies (19,22). Further, carotenoids (tocopherols and β-carotene) also take part in RoS quenching (2) and the time-dependent rise of these pigments in UV-c irradiated plants showed that probably pea cells switched on defence mechanism/s to cope with the negative stress consequences.…”

“…Salicylic acid (SA) has various physiological functions including induction of plant resistance to biotic and abiotic stresses (Mauch-Mani and Métraux 1998, Metwally et al 2003, He et al 2005, Mahdavian et al 2008. It has been reported that SA ameliorates the damaging effects of salinity by sustaining photosynthetic and transpiration rate and content of K + (El-Tayeb 2005, Arfan et al 2007, Stevens et al 2006.…”

Effects of exogenous salicylic acid (SA) on plant growth, contents of Na, K, Ca and Mg, activities of superoxide dismutase (SOD), guaiacol peroxidase (GPX), ascorbate peroxidase (APX), dehydroascorbate reductase (DHAR), glutathione reductase (GR) and catalase (CAT), and contents of ascorbate and glutathione were investigated in tomato (Lycopersicon esculentum L.) plants treated with 100 mM NaCl. NaCl treatment significantly increased H 2 O 2 content and lipid peroxidation indicated by accumulation of thiobarbituric acid reactive substances (TBARS). A foliar spray of 1 mM SA significantly decreased lipid peroxidation caused by NaCl and improved the plant growth. This alleviation of NaCl toxicity by SA was related to decreases in Na contents, increases in K and Mg contents in shoots and roots, and increases in the activities of SOD, CAT, GPX and DHAR and the contents of ascorbate and glutathione.

“…Ervin et al (2004) found that exogenous SA application alleviated the damaging effects induced by UV-B radiation in Kentucky bluegrass. SA stimulates photosynthetic machinery by increasing the content of chlorophyll in UV-stressed plants (Mahdavian et al, 2008). Stratmann (2003) reported that UV radiation may influence JA levels and lead to an overlap in gene expression caused by UV-B and herbivory.…”

The increased ultraviolet-B (UV-B) radiation (280-320 nm) on the Earth's surface is one of the most important concerns of global change. This concern is primarily because increased UV-B radiation has been unambiguously shown to be responsible for the majority of harmful effects on aquatic as well as terrestrial organisms, and thus influence ecological interactions. For the past 4 plus decades, many studies have been conducted on the damaging effects of elevated UV-B radiation on plants. These studies have shown a diverse range of responses to UV-B radiation, and might be in general arbitrarily divided into two classes, photomorphogenic and stress responses at the morphological, physiological, biochemical and molecular levels. Crop plants evolved different adaptive or defensive mechanisms to UV-B radiation, including accumulation of UV-absorbing sunscreens, production of enzymatic and non-enzymatic antioxidants, changes of phytohormones or activation of DNA-repairing enzymes. A diagram illustrating the general responses of UV-B radiation and complexity of the interactions among factors was developed. Three urgent specific researches are proposed, which might provide opportunities for genetic engineering and possibility of breeding to deal with potential crop yield reductions due to elevated UV-B in agricultural systems, and thus will play a major role in determining the crops future.
