“…Rodríguez-Serrano et al [70] demonstrated that Cd toxicity strongly depressed the activity of NO-synthase dependent NO production in Pisum sativum seedlings; however, exogenous Ca supply ameliorated this efect due to enhanced JA and ET production. Interplay among NO, H 2 O 2 , and SA has also been reported in lupine seedlings [71] and ryegrass plants [72] under Cd stress. Application of putrescine (Put) and NO in combination was reported to alleviate Cd toxicity in Vigna radiate by triggering the activity of both enzymatic and nonenzymatic antioxidant machinery and a parallel increase in phytochelatin synthesis [73].…”

Phytohormones - Signaling Mechanisms and Crosstalk in Plant Development and Stress Responses

Plants, being sessile, are concurrently exposed to various biotic and abiotic stresses. The perception of stress signals in plants involves a wide spectrum of signal transduction pathways that interact to induce tolerance against adverse environmental conditions. This functional overlapping among various stress signaling cascades also leads to the expression of genes that regulate biosynthesis or action of other hormones. Phytohormonal signals, activated by both developmental and environmental responses, play a crucial role to develop stress tolerance in plants. Nitric oxide (NO) is one of the major players in plant signaling networks. Emerging evidence supports that NO interplays with signaling pathways of auxins, gibberellins, abscisic acid, ethylene, jasmonic acid, brassinosteroids, and other plant hormones to control metabolism, growth, and development in plants. This chapter focuses on the current state of knowledge of cross talk between signaling pathways of NO and phytohormones in plants exposed to various abiotic stresses.

“…Many studies suggested that decreasing leaf chlorophyll content was one of the most general toxicity effects of Cd on plants (Chen et al 2008(Chen et al , 2010, which was confirmed in this study. However, more and more researches reported that exogenous NO could alleviate Cdinduced chlorophyll synthesis inhibition (Chen et al 2010;Wang et al 2013). In this study, Cd-decreased chlorophyll content was recovered to the level of normal plants when peanut plants were treated with exogenous NO at sowing and seedling stages (Figure 1), accompanied by the recovery of P n and T r , which was severely affected by 50 mg kg…”

“…Increasing evidence indicates that exogenous NO plays important roles in plant tolerance to Cd stress (Hsu & Kao 2004;Laspina et al 2005;Xiong et al 2009;Wang et al 2013). In our lab, Zhang et al (2012) supplied SNP (a donor of NO) for peanut plants growing on calcareous soil and their study found that the SNP added into the soil effectively increased peanut tolerance to Fe deficiency stress.…”

“…Xiong et al (2009) demonstrated that exogenous NO enhanced Cd tolerance of rice by increasing the pectin and hemicellulose content in the cell wall of roots. In addition, our previous study also indicated that NO supply can alleviate Cd toxicity by increasing antioxidant capacity, improving uptake of nutrition elements, and restricting Cd translocation from roots to shoots in perennial ryegrass (Wang et al 2013).…”

A pot experiment was conducted to study the effects of sodium nitroprusside (SNP, a nitric oxide [NO] donor) on cadmium (Cd) toxicity in peanut plants. SNP solution was poured into Cd-contaminated soil at sowing, seedling, flowering, and pod setting stages, respectively. The results showed that exogenous NO increased the biomass and yield of peanuts and improved chlorophyll content, photosynthesis (P n ), and transpiration (T r ). Cd-induced oxidative damages were eliminated by exogenous NO, reflected by decreased accumulation of superoxide anion (O À 2 ), hydrogen peroxide (H 2 O 2 ), and malondialdehyde (MDA). Moreover, exogenous NO increased Cd-decreased activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and soluble protein and proline contents also reached a normal level. Furthermore, exogenous NO improved the uptake of nutrient elements and reduced Cd accumulation in the roots, shoots, and kernels under Cd stress. These data suggest that SNP application at sowing and seedling stages had better alleviation effects on Cd toxicity in peanut plants.
