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

Stresses, Год журнала: 2023, Номер 3(3), С. 570 - 585

Опубликована: Авг. 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

Antioxidants, Год журнала: 2023, Номер 12(3), С. 666 - 666

Опубликована: Март 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.
