“…Under nitrogen shortage ( Radin and Mauney, 1986 ; Délano-Frier et al, 2011 ; Li S. et al, 2020 ) and drought stress ( Soma et al, 2021 ), ABA is also crucial for root development and architectural alterations. Dehydrins, osmoprotectants, and protective proteins are all biosynthesized with ABA ( Fernando and Schroeder, 2016 ; Hossain et al, 2022 ).…”

Plants often face incompatible growing environments like drought, salinity, cold, frost, and elevated temperatures that affect plant growth and development leading to low yield and, in worse circumstances, plant death. The arsenal of versatile compounds for plant consumption and structure is called metabolites, which allows them to develop strategies to stop enemies, fight pathogens, replace their competitors and go beyond environmental restraints. These elements are formed under particular abiotic stresses like flooding, heat, drought, cold, etc., and biotic stress such as a pathogenic attack, thus associated with survival strategy of plants. Stress responses of plants are vigorous and include multifaceted crosstalk between different levels of regulation, including regulation of metabolism and expression of genes for morphological and physiological adaptation. To date, many of these compounds and their biosynthetic pathways have been found in the plant kingdom. Metabolites like amino acids, phenolics, hormones, polyamines, compatible solutes, antioxidants, pathogen related proteins (PR proteins), etc. are crucial for growth, stress tolerance, and plant defense. This review focuses on promising metabolites involved in stress tolerance under severe conditions and events signaling the mediation of stress-induced metabolic changes are presented.

“…Enhancement of ROS has also been reported by Mishra et al (2011) during abiotic sress. Various undesirable and growth deterent changes in the plants are there as a result of production of ROS for example hampering of ATP synthesis and DNA blight (Hossain et al, 2022). To attenuate the scars of ROS production, plants have choosen a myriad of composite enzyme apparatus known as antioxidant enzyme system.…”

Rapidly expanding industrial areas ensues a negative impact on the soil chemistry, it delivers certain stubborn heavy metals in the soil. Inefficient emission management and pollution alleviation contributes discharge of heavy metals in the surroundings causing a threat to mankind. To subside the effect of heavy metal; most effective, cost free, solardriven, green technology phytoremediation has been adopted which indulges exploitation of hyper-accumulator plants. Heavy metal toxicity leads to production of reactive oxygen species causing oxidative stress to the plant cell. To mitigate the oxidative stress plant cell initiates production of antioxidative enzymes. The present experiment was setup for analysis and assessment of comparative study of physical (electrokinetic remediation) and chemical (chelators) amendments in enhancing antioxidative enzymes in response to the metal phytoxicity in Vetiveria zizanioides.

Plant photosynthesis and biomass production are closely associated traits but critical to unfavorable environmental constraints such as salinity and drought. The relationships among stress tolerance, photosynthetic mechanisms, biomass and ethanol yield were assessed in Phragmites karka. The growth parameters, leaf gas exchange and chlorophyll fluorescence of P. karka were studied when irrigated with the control and 100 and 300 mM NaCl in a nutrient solution and water deficit conditions (drought, at 50% water holding capacity). The plant shoot fresh biomass was increased in the low NaCl concentration; however, it significantly declined in high salinity and drought. Interestingly the addition of low salinity increased the shoot biomass and ethanol yield. The number of tillers was increased at 100 mM NaCl in comparison to the control treatment. High salinity increased the photosynthetic performance, but there were no significant changes in drought-treated plants. The saturated irradiance (Is) for photosynthesis increased significantly in low salinity, but it declined (about 50%) in high salt-stressed and (about 20%) in drought-treated plants compared to the control. The rates of dark respiration (Rd) and compensation irradiance (Ic) were decreased significantly under all treatments of salinity and drought, with the exception of unchanged Rd values in the control and drought treatments. A-Ci curve analyses revealed a significant improvement in the Jmax, Vc, max, and triose-phosphate utilization (TPU) at lower salinity levels but decreased at 300 mM NaCl and drought treatments compared to the control. In the chlorophyll fluorescence parameters (Fv/Fm, maximum photochemical quantum yield of PSII, and Y(NO)), the non-photochemical yields were not affected under the salt and drought treatments, although an effective photochemical quantum yield (YII) and electron transport rate (ETR) were significantly enhanced in water deficit compared to control plants. P. karka regulates an efficient photosynthesis mechanism to grow in saline and arid areas and can therefore be used as a sustainable biofuel crop.
