“…These enzymes may be manipulated, overexpressed, or down-regulated depending on the strength of stress, duration, enzyme type, plant species, etc. Various workers have reported increased activities of many antioxidant enzymes in plants to overcome the oxidative stress induced by biotic or abiotic stresses 27 . In all cases, these enzymes are encoded by multiple gene families and are present in several compartments of the cells.…”

In the era of global warming, stress combinations instead of individual stress are realistic threats faced by plants that can alter or trigger a wide range of plant responses. In the current study, the cumulative effect of charcoal rot disease caused by notorious fungal pathogen viz., Macrophomina phaseolina was investigated under toxic levels of copper (Cu) in mash bean, and farmyard manure (FYM) was employed to manage stress. Therefore, Cu-spiked soil (50 and 100 mg/kg) was inoculated with the pathogen, and amended with 2% FYM, to assess the effect of intricate interactions on mash bean plants through pot experiments. Results demonstrated that the individual stress of the pathogen or Cu was more severe for morpho-growth, physio-biochemical, and expression profiles of stress-related genes and total protein in mash bean plants as compared to stress combinations. Under single Cu stress, a significant amount of Cu accumulated in plant tissues, particularly in roots than in upper ground tissues, while, under stress combination less Cu accumulated in the plants. Nonetheless, 2% FYM in soil encountered the negative effect of stress responses provoked by the pathogen, Cu, or both by improving health markers (photosynthetic pigments, reducing sugar, total phenolics) and oxidative stress markers (catalase, peroxidase, and polyphenol oxidase), together with regulating the expression of stress-related genes (catalase, ascorbate peroxidase, and cytokinin-resistant genes), and proteins, besides decreasing Cu uptake in the plants. FYM worked better at lower concentrations (50 mg/kg) of Cu than at higher ones (100 mg/kg), hence could be used as a suitable option for better growth, yield, and crop performance under charcoal rot disease stress in Cu-contaminated soils.

In the era of global warming, stress combinations instead of individual stresses are realistic threats faced by plants, which affect the metabolic activities in an inimitable mode unlike individual stress. In the current study, charcoal rot disease stress caused by notorious fungal pathogen viz., Macrophomina phaseolina (Tassi) Goid coupled with toxic levels of heavy metal copper (Cu) was investigated on morpho-physio-biochemical and molecular responses in mash bean [Vigna mungo (L.) Hepper] plants. Soil application with 2% Farmyard manure (FYM) was also used as a warfare agent against the stress/s responses in the plans. Therefore, soil spiked Cu (50 and 100 mg/kg) was inoculated with the pathogen, amended with 2% FYM was sown with mash bean seeds. The individual stress of MP or Cu resulted in more drastic changes in biological (growth, biomass, and yield), and physio-biochemical [(total chlorophyll content, carotenoids, reducing sugar total protein content, and total phenolic, catalase (CAT), peroxidase (POX) and polyphenol oxidase (PPO)] attributes with the greater translocation factors and bioaccumulation factors as compared to stress combination. The expression levels of catalase, ascorbate peroxidase, cytokinin-resistant gene as well as protein profiling and other metabolic changes (activity of CAT, POX, and PPO) were more up regulated under single stress conditions by mash bean plants. Alteration in studied parameters in mash bean plants provided the basis of cross-tolerance (hormesis) induced by Cu against the pathogen under stress combination. Nonetheless, 2% FYM in soil encounters the negative effect of stress responses provoked by the pathogen, Cu or both by decreasing Cu uptake by the plants. FYM worked better at lower concentrations (50 mg/kg) of Cu than at higher ones (100 mg/kg), hence could be used as a suitable option to reclaim soil health and better plant productivity.

Plant Abiotic Stress Responses and Tolerance Mechanisms

View full text Add to dashboard Cite

All life forms, from the simplest to the most complicated, are inevitably exposed to altering environmental conditions in their natural habitats, gradually depending on their lifestyle. Unfavorable alterations drive these life forms either to avoidance or defense as a response. Most of the essential plant growth-promoting environmental factors can also turn out to be stress factors. Water as the most abundant molecule of all living cells can cause stress either in deficit as drought or in excess as waterlogging. Temperature is important for the maintenance of all biomolecules and metabolic reactions; hence, both low and high temperatures are deleterious stress factors. Even though the plants were exposed to various volcanic origin, heavy metals and pollutants and evolved molecular mechanisms during millions year of evolution, rapid urbanization, and industrial progress introduce brand new pollutants as micro- and nanoplastics as well as nanoparticles to plants like never before. This chapter defines and evaluates major environmental abiotic stress factors with an emphasis on the latest knowledge of molecular effects on plants. In addition, novel stress factors, such as nanoparticles and microplastics, are looked over as hot prospects for the future of plant abiotic stress areas.
