ABSTRACT Hydrogen gas (H 2 ) was recently proposed as a novel antioxidant and signalling molecule in animals. However, the physiological roles of H plants are less clear. Here, we showed that exposure alfalfa seedlings to paraquat stress increased endogenous production. When supplied with exogenous or heme oxygenase‐1 (HO‐1)‐inducer hemin, displayed enhanced tolerance oxidative induced by paraquat. This evidenced alleviation inhibition root growth, reduced lipid peroxidation decreased...
Until now, physiological mechanisms and downstream targets responsible for the cadmium (Cd) tolerance mediated by endogenous hydrogen sulfide (H2S) have been elusive. To address this gap, a combination of pharmacological, histochemical, biochemical molecular approaches was applied. The perturbation reduced (homo)glutathione homeostasis increased H2S production as well activation two H2S-synthetic enzymes activities, including L-cysteine desulfhydrase (LCD) D-cysteine (DCD), in alfalfa...
This work examines the involvement of haem oxygenase-1 (HO-1) in salicylic acid (SA)-induced alleviation oxidative stress as a result cadmium (Cd) alfalfa (Medicago sativa L.) seedling roots. CdCl2 exposure caused severe growth inhibition and Cd accumulation, which were potentiated by pre-treatment with zinc protoporphyrin (ZnPPIX), potent HO-1 inhibitor. Pre-treatment plants inducer haemin or SA, both could induce MsHO1 gene expression, significantly reduced accumulation. The effects also...
Metabolism of molecular hydrogen (H2) in bacteria and algae has been widely studied, it attracted increasing attention the context animals plants. However, role endogenous H2 lateral root (LR) formation is still unclear. Here, our results showed that H2-induced a universal event. Naphthalene-1-acetic acid (NAA; auxin analog) was able to trigger production tomato seedlings, contrasting response observed presence N-1-naphthyphthalamic (NPA), an transport inhibitor. NPA-triggered inhibition...
External administration of hydrogen gas (H2) benefits plants from multiple environmental stimuli. However, the physiological significance and molecular mechanism H2 in ultraviolet-B (UVB) irradiation are largely unexplored. Here, biological function regulation plant UVB-tolerance was investigated by using hydrogen-rich water (HRW). Results showed that exposure alfalfa seedlings to UVB increased endogenous production. Pretreatment with HRW mimicked UVB-induced Corresponding UVB-triggered...
Abstract Background Hydrogen gas (H 2 ) is hypothesised to play a role in plants that are coping with stresses by regulating signal transduction and gene expression. Although the beneficial of H plant tolerance cadmium (Cd) has been investigated previously, corresponding mechanism not elucidated. In this report, transcriptomes alfalfa seedling roots under Cd and/or hydrogen-rich water (HRW) treatment were first analysed. Then, sulfur metabolism pathways focused on further pharmacological...
Previous pharmacological results confirmed that haem oxygenase-1 (HO-1) is involved in protection of cells against ultraviolet (UV)-induced oxidative damage soybean [Glycine max (L.) Merr.] seedlings, but there remains a lack genetic evidence. In this study, the link between Arabidopsis thaliana HO-1 (HY1) and UV-C tolerance was investigated at molecular levels. The maximum inducible expression HY1 wild-type observed following irradiation. sensitivity not ho2, ho3, ho4 single double mutants....
Despite substantial evidence showing the ammonium-altered redox homeostasis in plants, involvement and molecular mechanism of heme-heme oxygenase 1 (heme-HO1), a novel antioxidant system, regulation ammonium tolerance remain elusive. To fill these gaps, biological function rice HO1 (OsSE5) was investigated. Results showed that NH4 Cl up-regulated OsSE5 expression. Oxidative stress subsequent growth inhibition induced by excess partly mitigated pretreatment with carbon monoxide (CO,...
Our previous studies revealed that methane (CH4 ) induces adventitious rooting in cucumber. However, the corresponding molecular mechanism is still elusive. In this work, we discovered CH4 triggered accumulation of nitric oxide (NO) and thereafter cucumber rooting, mimicking inducing effects sodium nitroprusside (SNP) NONOate (two NO-releasing compounds). Above mentioned responses were sensitive to NO scavenger(s), showing root development respectively impaired. Inhibitor test biochemical...
