“…The alleviation of Cd stress by NO may be related to increased chlorophyll content (Table 2), improved nutrient balance (Table 3) A notable reduction of chlorophyll parameters occurred in ryegrass seedlings exposed to 100 μM and 150 μM Cd stress (Table 2). Several authors reported a decreased chlorophyll content in the leaves of Cdtreated plants (Belkhadi et al, 2010). The decrease in chlorophyll content in Cd-affected ryegrass seedlings might be attributed to the possible oxidation of chlorophyll and the damaged ultrastructure of chloroplasts (Chen et al, 2010).…”

The effects of sodium nitroprusside (SNP, a donor of NO) on cadmium (Cd) toxicity in ryegrass seedlings (Lolium perenne L.) were studied. 100 and 150 μM Cd stress had a detrimental effect on ryegrass seedlings. Exposure of 100 and 150 μM Cd inhibited plant growth, decreased chlorophyll concentration, and reduced the absorption of Fe, Cu and Zn. Excess Cd also altered the activities of antioxidant enzymes, and increased the accumulation of reactive oxygen species (ROS). Exogenous NO alleviated Cd toxicity of ryegrass plants, especially under the stress of 150 μM Cd, as evidenced by improved plant growth and increased concentrations of chlorophyll and mineral nutrients. Exogenous NO also mitigated oxidative stress by regulating the activities of antioxidant enzymes and the contents of non-antioxidants. Moreover, the absorption of Fe, Cu and Zn was increased, indicating that exogenous NO stimulated H + -ATPase activity to promote sequestration or uptake of ions. The applications of NO also reduced the translocation of Cd from roots to the leaves. These results indicate that the mechanisms of NO for mitigating Cd toxicity may be associated with reduced root-to-shoot translocation of Cd and enhanced capacity of antioxidative systems to protect plants from oxidative stress.

“…Mutations in several genes that encode chloroplast/plastid-localized proteins alter SA synthesis and plant defence signalling (Wildermuth et al 2001;Slaymaker et al 2002), suggesting that the SA pathway is important for food body production. Belkhadi et al (2010) demonstrated that SA leads to the increase in tri-unsaturated fatty acids in Linum usitatissimum. In contrast to the JA pathway, which depends on UV-B, the SA pathway depends on red to far-red (R:FR) ratio (detected by phytochromes) (Ballar e et al 2012).…”

“…The effects of copper on S. alterniflora showed that the excess of Cu with ameliorate membrane permeability lead to the production of superoxide radicals and oxidative stress in plants, and then lead to the enhancement of lipid per oxidation in cell membrane [34]. This issue has been confirmed in several studies concerning the: 1) effect of lead and Cd in mung bean [35], 2) lead on sedum [36], 3) Cd on in Linum usitatissimum L [37], and 4) copper on duckweed, cucumber, and Silene paradoxa L [8,[38][39].…”

Nowadays, the contaminations generated by anthropogenic activities have had damaging effects on the life cycle of plants, particularly on the plants living in the vicinity of urban areas that are more associated with the life of people. Bamboo, as a local plant, is one of the most widely used plants in China. So, a pot experiment was conducted to investigate the effects of three HMs (Cu, Pb, and Zn) in four different concentrations (0 (for control), 500 mg/kg, 1000 mg/kg, and 200 mg/kg), with complete randomized design (CRD) by five replications for each treatment to measure the antioxidant enzymes, lipid per oxidation (LP), soluble protein (SP), gas exchange parameters, and morphological indexes in Sasa kongosanensis f. aureostriatus. The results indicated that the antioxidant responses had an arc-shaped trend with various alterations in which POD and CAT first increase with low concentration of HMs (500 mg/kg) and then decrease with the increase of heavy metal (1000 mg/kg and 2000 mg/kg). Additionally, measuring of MDA content and soluble protein illustrated that MDA content and soluble protein increase with excess of HMs in different levels, and also the excess of HMs significantly decreases the photosynthesis properties. Moreover, the results obtained by morphological indices showed that low concentration of HMs increases both percentage of shoot length and percentage of emerge plants at all three kinds of HMs, but observe a downward trend with excess of heavy metal in 1000 mg/kg and 2000 mg/kg. Overall, in "Sasa kongosanensis f. aureo -striatus, results indicated that low concentration of HMs (500 mg/kg) can help the plant growth, while excess of HMs (1000-2000 mg/kg) alleviates the plant growth. On the other hand, Pb revealed the lowest antioxidant
