“…Moreover, an NO-induced decrease of Cd translocation was reported in many plants (Xiong et al 2009, Wang et al 2013a. Our previous study also revealed that the application of SA and SNP decreases Cd translocation from roots to shoots (Wang et al 2013b). The reason of a minority of Cd in peanut shoots might be that SA and NO protected the plants from the membrane damage.…”

“…The addition of SA and SNP to the medium with Cd effectively alleviated the Cd-stress. It has been shown that SA and NO act as plant growth regulators that can separately or together counteract a Cd-induced decrease in plant growth (Shi et al 2009, Xu et al 2010, Wang et al 2013b. Many studies reported that SA reduces detrimental effects of Cd on different plants (Guo et al 2007(Guo et al , 2009.…”

“…SA and NO have been reported to induce a number of defence responses to abiotic stresses (Shi et al 2009, Kazemi et al 2010, Wang et al 2013b. In this work, we analyzed the possible roles of exogenous SAand SNP (a donor of NO) in the amelioration of Cd toxicity in two peanut cultivars (Huayu 22 and Xiaobaisha).…”

The interactive effects of salicylic acid (SA) and nitric oxide (NO) on alleviating cadmium (Cd) toxicity in peanut (Arachis hypogaea L.) were studied. Seedlings of two cultivars (Huayu 22 -a big seed type, and Xiaobaisha -a small seed type) were treated with 200 µM CdCl 2 without or with 0.1 mM SA or 0.25 mM sodium nitroprusside (SNP, an NO donor). Results show that the Cd exposure depressed plant growth of both the cultivars but more of Huayu 22 than of Xiaobaisha. Exogenous SA and NO alleviated Cd toxicity in both the peanut cultivars: they improved growth, chlorophyll content, photosynthesis, and mineral nutrition. Furthermore, exogenous SA or NO decreased oxidative stress by increasing activities of antioxidant enzymes and content of non-antioxidants. Besides, in roots and leaves of both the cultivars, exogenous SA and NO increased Cd accumulation in the cell wall and decreased Cd distribution to organelles. In particular, the effect of SA+SNP was most obvious.

“…In the present study, the soluble protein content in leaves and roots declined under Cd stress, especially at 150 μM Cd (Figure 2b). Our studies coincide with Wang et al (2013) Metal excess typically depresses accumulation of mineral nutrients in plants (Kovacik et al, 2014a).…”

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.
