Alleviation of copper phytotoxicity by acetylsalicylic acid and nitric oxide application in mung bean involves the up-regulation of antioxidants, osmolytes and glyoxalase system

The study assessed the individual and interactive role of acetylsalicylic acid (ASA) nitric oxide (NO) against excess copper (Cu) concentrations. Excess Cu significantly reduced growth photosynthesis, although application ASA NO mitigated reduction with much visible effect in their combination. oxidative effects have been evident as increased reactive oxygen species (ROS) production, resulting malondialdehyde (MDA) membrane stability index (MSI). Both damage obvious MDA lipoxygenase (LOX) down-regulation. Up-regulation enzymatic non-enzymatic antioxidants due to contributed quick elimination ROS. Oxidative were by osmolyte accumulation, up-regulation ?-Glutamyl kinase (? -GK), glyoxalase, down-regulation proline oxidase (PROX). Reduced accumulation our showed crosstalk protection mung bean damaging Cu.
