Plants are adversely affected by a wide range of abiotic and biotic stresses during their life cycle. In real ecological environments, multiple often occur simultaneously have huge effects on the yield nutritional content crops. Crosstalk is regarded to exist between these different stresses. To date, most research focuses interaction plants single stress, much remains be discussed response crosstalk more than one stress. imposed with stress been shown affect responses other evolved sophisticated networks through long-term coexistence Transcription factors, as master regulators stress-responsive genes, crucial nodes posed excellent candidates for crop improvement.

Exogenous Sodium Nitroprusside Mitigates Salt Stress in Lentil (Lens culinaris Medik.) by Affecting the Growth, Yield, and Biochemical Properties

Molecules, Journal Year: 2021, Volume and Issue: 26(9), P. 2576 - 2576

Published: April 28, 2021

Soil salinity disrupts the physiological and biochemical processes of crop plants ultimately leads to compromising future food security. Sodium nitroprusside (SNP), a contributor nitric oxide (NO), holds potential alleviate abiotic stress effects boost tolerance in plants, whereas less information is available on its role salt-stressed lentils. We examined effect exogenously applied SNP lentil by monitoring plant growth yield-related attributes, biochemistry enzymes (superoxide dismutase (SOD), catalase (CAT), peroxidase (POD)) amassing leaf malondialdehyde (MDA) hydrogen peroxide (H2O2). Salinity was induced NaCl application at concentrations 50 mM (moderate salinity) 100 (severe salinity), while it alleviated µM µM. severely inhibited length roots shoots, relative water content, chlorophyll content leaves, number branches, pods, seeds, seed yield, biomass per plant. In addition, MDA, H2O2 as well SOD, CAT, POD activities were increased with increasing levels. Plants supplemented (100 µM) showed significant improvement growth- yield-contributing parameters, especially grown under moderate (50 NaCl). Essentially, remained effective rescue regulating pathways. Thus, exogenous could be developed useful strategy for improving performance salinity-prone environments.
