Phytohormone Priming: Regulator for Heavy Metal Stress in Plants

Journal of Plant Growth Regulation, Journal Year: 2018, Volume and Issue: 38(2), P. 739 - 752

Published: Nov. 27, 2018

Phytohormones act as chemical messengers and, under a complex regulation, allow plants to sustain biotic and abiotic stresses. Thus, phytohormones are known for their regulatory role in plant growth development. Heavy metals (HMs) play an important metabolism have roles development micronutrients. However, at level above threshold, these HMs contaminants pose worldwide environmental threat. finding eco-friendly economical deliverables tackle this problem is priority. In addition physicochemical methods, exogenous application of phytohormones, i.e., auxins, cytokinins, gibberellins, can positively influence the regulation ascorbate–glutathione cycle, transpiration rate, cell division, activities nitrogen assimilation, which improve activity. Brassinosteroids, ethylene salicylic acid been reported enhance anti-oxidant system, decrease levels ROS, lipid peroxidation photosynthesis plants, when applied exogenously HM effect. There crosstalk between activated upon application. Research suggests that primed by stress tolerance. Chemical priming has provided good results physiology adaptation, phytohormone underway. We reviewed promising potentially confer enhanced tolerance used exogenously. Exogenous may increase performance be agro-ecological benefits conditions with high level.

Developing climate‐resilient crops: improving plant tolerance to stress combination

The Plant Journal, Journal Year: 2021, Volume and Issue: 109(2), P. 373 - 389

Published: Sept. 5, 2021

SUMMARY Global warming and climate change are driving an alarming increase in the frequency intensity of different abiotic stresses, such as droughts, heat waves, cold snaps, flooding, negatively affecting crop yields causing food shortages. Climate is also altering composition behavior insect pathogen populations adding to yield losses worldwide. Additional constraints agriculture caused by increasing amounts human‐generated pollutants, well negative impact on soil microbiomes. Although laboratory, we trained study individual stress conditions plants, field many pests could simultaneously or sequentially affect combination. Because expected combination events (e.g., waves combined with drought, other and/or pathogens), a concentrated effort needed how crops. This need particularly critical, studies have shown that response plants unique cannot be predicted from simply studying each stresses part Strategies enhance tolerance particular may therefore fail this specific stress, when factors. Here review recent combinations propose new approaches avenues for development combination‐ change‐resilient

Regulation of ROS Metabolism in Plants under Environmental Stress: A Review of Recent Experimental Evidence

International Journal of Molecular Sciences, Journal Year: 2020, Volume and Issue: 21(22), P. 8695 - 8695

Published: Nov. 18, 2020

Various environmental stresses singly or in combination generate excess amounts of reactive oxygen species (ROS), leading to oxidative stress and impaired redox homeostasis. Generation ROS is the obvious outcome abiotic gaining importance not only for their ubiquitous generation subsequent damaging effects plants but also diversified roles signaling cascade, affecting other biomolecules, hormones concerning growth, development, regulation tolerance. Therefore, a good balance between antioxidant defense system protects photosynthetic machinery, maintains membrane integrity, prevents damage nucleic acids proteins. Notably, scavenges regulates titer signaling. A glut studies have been executed over last few decades discover pattern scavenging. Reports suggested sharp threshold level being beneficial toxic, depending on plant species, growth stages, types stresses, intensity, duration. Approaches towards enhancing one vital areas research biologists. this review, we accumulated discussed physicochemical basis production, cellular compartment-specific pathways, possible distressing effects. Moreover, function detoxification homeostasis maximizing light latest endeavors experimental evidence.

On the world stage, increase in temperatures due to global warming is already a reality that has become one of main challenges faced by scientific community. Since agriculture highly dependent on climatic conditions, it may suffer great impact short term if no measures are taken adapt and mitigate agricultural system. Plant responses abiotic stresses have been subject research numerous groups worldwide. Initially, these studies were concentrated model plants, and, later, they expanded their several economically important crops such as rice, corn, soybeans, coffee, others. However, agronomic evaluations for launching cultivars classical genetic improvement process focus, above all, productivity, historically leaving factors tolerance background. Considering importance can term, new strategies currently being sought adopted breeding programs understand physiological, biochemical, molecular environmental disturbances plants interest, thus ensuring food security. Moreover, integration approaches bringing insights breeding. We will discuss how water deficit, high temperatures, salinity exert effects plants.
