Published: March 30, 2021

Accumulation of reactive oxygen species (ROS), and their destructive effects on cellular organelles are the hallmark features plants exposed to abiotic stresses. Plants well-equipped with defensive mechanisms like antioxidant systems deal ROS-induced oxidative stress. Silicon has been emerged as an important regulator plant protective under environmental stresses, which can be up-taken from soil through a system various silicon-transporters. In plants, silicon is deposited underneath cuticles in cell wall, help cells reduce deleterious Furthermore, provide resistance ROS-toxicity, often accounts for silicon-mediated improvement tolerance different constraints, including salinity, drought, metal toxicity. enhances ROS-detoxification ability treated by modulating defense systems, expression key genes associated stress mitigation hormone metabolism. also displays additive roles ROS-elimination when supplied other external stimuli. Here, we discuss recent findings how able modulate response triggered constraints. We review interactions signaling molecules, nitric oxide, ROS, polyamines, phytohormones mediation protection against stress-induced damage.

The Key Roles of ROS and RNS as a Signaling Molecule in Plant–Microbe Interactions

Antioxidants, Journal Year: 2023, Volume and Issue: 12(2), P. 268 - 268

Published: Jan. 25, 2023

Reactive oxygen species (ROS) and reactive nitrogen (RNS) play a pivotal role in the dynamic cell signaling systems plants, even under biotic abiotic stress conditions. Over past two decades, various studies have endorsed notion that these molecules can act as intracellular intercellular at very low concentration to control plant growth development, symbiotic association, defense mechanisms response However, upsurge of ROS RNS stressful conditions lead damage, retarded growth, delayed development plants. As molecules, gained great attention from scientists been studied different developmental stages plant-microbe interactions is still unknown. Different organelles cells contain enzymes necessary for formation well their scavengers, spatial temporal positions determine pathways. In present review, we aimed report production RNS, during interactions, antioxidant system balancing synthesis elimination species.

An Overview of Plant Phenolics and Their Involvement in Abiotic Stress Tolerance

Stresses, Journal Year: 2023, Volume and Issue: 3(3), P. 570 - 585

Published: Aug. 8, 2023

Secondary metabolites, such as phenols and salicylic, play a crucial role in the regulation of development tolerance mechanisms against wide range stresses. During adverse conditions biotic abiotic stresses, plants induce biosynthesis phenolic compounds to provide tolerance. Phenolics are secondary aromatic metabolites synthesized through shikimate/phenylpropanoid pathway or polyketide acetate/malonate pathway, which produce monomeric polymeric phenolics. Phenolic not only take part preventing stresses but also regulating physiological activities. These significantly regulate both below- above-ground defense mechanisms. Plants synthesize thousands throughout their evolution survive changing environments. Environmental factors, high light, cold, drought, heavy metals, etc., increase accumulation phenolics neutralize any toxic effects. This review focuses on updated studies

Abstract Globally, substantial research into endophytic microbes is being conducted to increase agricultural and environmental sustainability. Endophytic such as bacteria, actinomycetes, fungi inhabit ubiquitously within the tissues of all plant species without causing any harm or disease. Endophytes form symbiotic relationships with diverse can regulate numerous host functions, including resistance abiotic biotic stresses, growth development, stimulating immune systems. Moreover, endophytes play a dominant role in nutrient cycling, biodegradation, bioremediation, are widely used many industries. have stronger predisposition for enhancing mineral metal solubility by cells through secretion organic acids low molecular weight metal-specific ligands (such siderophores) that alter soil pH boost binding activity.

Accumulation of Proline in Plants under Contaminated Soils—Are We on the Same Page?

Antioxidants, Journal Year: 2023, Volume and Issue: 12(3), P. 666 - 666

Published: March 8, 2023

Agricultural soil degradation is occurring at unprecedented rates, not only as an indirect effect of climate change (CC) but also due to intensified agricultural practices which affect properties and biodiversity. Therefore, understanding the impacts CC on plant physiology crucial for sustainable development mitigation strategies prevent crop productivity losses. The amino acid proline has long been recognized playing distinct roles in cells undergoing osmotic stress. Due its osmoprotectant redox-buffering ability, a positive correlation between accumulation plants’ tolerance abiotic stress pointed out numerous reviews. Indeed, quantification used systematically by physiologists indicator degree measurement antioxidant potential plants under stressful conditions. Moreover, exogenous application shown increase resilience several factors, including those related such salinity exposure metals xenobiotics. However, recent data from studies often refer signal sensitivity with no clear improved activity or higher tolerance, when exogenously reliever. Nevertheless, endogenous levels are strongly modified these stresses, proving involvement responses. Hence, one main question arises—is augmentation always sign resilience? From this perspective, present review aims provide more comprehensive implications induced reinforcing idea that should be employed sole rather complemented further biochemical physiological endpoints.
