Hydrogen sulfide negatively regulates cd-induced cell death in cucumber (Cucumis sativus L) root tip cells

Abstract: Background Hydrogen sulfide (H2S) is a gas signal molecule involved in regulating plants tolerance to heavy metals stress. In this study, we investigated the role of H2S in cadmium-(Cd-) induced cell death of root tips of cucumber seedlings. Results The results showed that the application of 200 μM Cd caused cell death, increased the content of reactive oxygen species (ROS), chromatin condensation, the release of Cytochrome c (Cyt c)… Show more

“…Increased H 2 O 2 and MDA production during short-term exposure of cucumber cell cultures to Cd 2+ has been reported previously [47]. Many studies have revealed that a large number of Cd-responsive genes may be involved in ROS signal transduction [47]. The relevant signal transduction pathways include Ca-calmodulin system, hormones, and mitogenactivated protein kinase (MAPK) phosphorylation cascade, which converge by activating Cd-related ROS genes [34].…”

“…Cadmium pollution has attracted worldwide attention [ 21 ]. Cd toxicity can cause ROS elevation in plants, oxidative damage, lipid peroxidation, and growth inhibition [ 47 ]. Increased H 2 O 2 and MDA production during short-term exposure of cucumber cell cultures to Cd 2+ has been reported previously [ 47 ].…”

“…The function of H 2 S in plants subject to Cd-related stress has been extensively studied. Hydrogen sulfide could alleviate the Cd-induced inhibition of root growth in Arabidopsis [69], Medicago sativa [67,77], Brassica rapa [68,70,76], Setaria italica [71], Cucumis sativus [72,75], Solanum lycopersicum [74], and Hordeum vulgare [73]. Furthermore, the suppression of plant root growth caused by other heavy metals, such as chromium (Cr), lead (Pb), mercury (Hg), and nickel (Ni), could also be relieved when exposed to H 2 S [73,78,79,[82][83][84]92,93].…”

“…The homogenate was centrifuged at 16,000 × g for 20 min at 4 • C, and the supernatant was used for the assays. The activities of SOD, POD, and APX were determined according to established protocols (Luo et al, 2020). Nicotinamide adenine dinucleotide phosphate (NADPH) content was determined by following the method described previously, with slight modifications (Matsumura and Miyachi, 1980;Wei et al, 2019).…”
