Due to global climate change, abiotic stresses are affecting plant growth, productivity, and the quality of cultivated crops. Stressful conditions disrupt physiological activities suppress defensive mechanisms, resulting in stress-sensitive plants. Consequently, plants implement various endogenous strategies, including hormone biosynthesis (e.g., abscisic acid, jasmonic salicylic brassinosteroids, indole-3-acetic cytokinins, ethylene, gibberellic strigolactones) withstand stress conditions. Combined or single disrupts normal transportation solutes, causes electron leakage, triggers reactive oxygen species (ROS) production, creating oxidative Several enzymatic non-enzymatic defense systems marshal a plant’s antioxidant defenses. While responses protective role system have been well-documented recent investigations, interrelationships among hormones, neurotransmitters (NTs, such as serotonin, melatonin, dopamine, acetylcholine, γ-aminobutyric acid), defenses not well explained. Thus, this review discusses advances transgenic metabolic developments, potential interaction hormones with NTs response tolerance mechanisms. Furthermore, we discuss current challenges future directions (transgenic breeding genome editing) for improvement using modern molecular tools. The involved regulating systems, networks, abiotic-induced also discussed.

Insights into plant salt stress signaling and tolerance

Journal of genetics and genomics/Journal of Genetics and Genomics, Год журнала: 2023, Номер 51(1), С. 16 - 34

Опубликована: Авг. 29, 2023

Soil salinization is an essential environmental stressor, threatening agricultural yield and ecological security worldwide. Saline soils accumulate excessive soluble salts which are detrimental to most plants by limiting plant growth productivity. It of great necessity for efficiently deal with the adverse effects caused salt stress survival successful reproduction. Multiple determinants tolerance have been identified in plants, cellular physiological mechanisms response adaption intensely characterized. Plants respond signals rapidly initiate signaling pathways re-establish homeostasis adjusted metabolism. This review summarizes advances perception, signaling, plants. A better understanding resistance will contribute improving crop performance under saline conditions using multiple engineering approaches. The rhizosphere microbiome-mediated as well chemical priming enhanced also discussed this review.

Abiotic Stress in Crop Production

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(7), С. 6603 - 6603

Опубликована: Апрель 1, 2023

The vast majority of agricultural land undergoes abiotic stress that can significantly reduce yields. Understanding the mechanisms plant defenses against stresses and putting this knowledge into practice is, therefore, an integral part sustainable agriculture. In review, we focus on current findings in resistance to four cardinal stressors-drought, heat, salinity, low temperatures. Apart from description newly discovered signaling stress, review also focuses importance primary secondary metabolites, including carbohydrates, amino acids, phenolics, phytohormones. A meta-analysis transcriptomic studies concerning model Arabidopsis demonstrates long-observed phenomenon stressors induce different signals effects at level gene expression, but genes whose regulation is similar under most still be traced. analysis further reveals transcriptional modulation Golgi-targeted proteins response heat stress. Our highlights several are similarly regulated all conditions. These support central role phytohormones response, some these has not yet been studied. Finally, provides information about major European crop plants-wheat, sugar beet, maize, potatoes, barley, sunflowers, grapes, rapeseed, tomatoes, apples.

Although trace elements are essential for life, environmental contamination due to metal accumulation and overuse in various sectors, such as healthcare, agriculture, industry, cosmetics, poses significant health concerns. Exposure of plants heavy metals leads the overproduction reactive oxygen species (ROS) their ability change mitochondrial membrane permeability restrict action ROS clearance enzymes cellular antioxidant system. The interaction with membranes, heavy-metal-induced interactions directly or indirectly different macromolecules, signaling pathways pollutants oxidative stress exposed organisms. metal–ROS–cell axis affects pathological processes ATP depletion, excess production, respiratory chain damage, decoupling phosphorylation, death. This review focuses on discussing toxic effects plants, particular emphasis stress, its consequences, mitigation strategies.

Phenolic compounds or polyphenols are among the most common of secondary metabolism in plants. Their biosynthesis is characteristic all plant cells and carried out with participation shikimate acetate-malonate pathways. In this case, various structures formed, such as phenylpropanoids, flavonoids, oligomeric polymeric phenolic nature. number already exceeds 10,000. The diversity phenolics affects their biological activity functional role. Most representatives characterized by interaction reactive oxygen species, which manifests itself not only plants but also human body, where they enter through food chains. Having a high activity, successfully used medicines nutritional supplements for health population. accumulation depend on many factors, including physiological-biochemical, molecular-genetic, environmental factors. review, we present latest literature data structure classes compounds, antioxidant biosynthesis, molecular genetic aspects (genes transfactors).

Reactive oxygen species: Multidimensional regulators of plant adaptation to abiotic stress and development

Journal of Integrative Plant Biology, Год журнала: 2023, Номер 66(3), С. 330 - 367

Опубликована: Дек. 20, 2023

Reactive oxygen species (ROS) are produced as undesirable by-products of metabolism in various cellular compartments, especially response to unfavorable environmental conditions, throughout the life cycle plants. Stress-induced ROS production disrupts normal function and leads oxidative damage. To cope with excessive ROS, plants equipped a sophisticated antioxidative defense system consisting enzymatic non-enzymatic components that scavenge or inhibit their harmful effects on biomolecules. Nonetheless, when maintained at relatively low levels, act signaling molecules regulate plant growth, development, adaptation adverse conditions. Here, we provide an overview current approaches for detecting ROS. We also discuss recent advances understanding signaling, metabolism, roles growth responses abiotic stresses.

Опубликована: Фев. 7, 2023

Climate change and abiotic stress factors are key players in crop losses worldwide. Among which, extreme temperatures (heat cold) disturb plant growth development, reduce productivity and, severe cases, lead to death. Plants have developed numerous strategies mitigate the detrimental impact of temperature stress. Exposure leads accumulation various metabolites, e.g. sugars, sugar alcohols, organic acids amino acids. accumulate acid 'proline' response several stresses, including Proline abundance may result from de novo synthesis, hydrolysis proteins, reduced utilization or degradation. also tolerance by maintaining osmotic balance (still controversial), cell turgidity indirectly modulating metabolism reactive oxygen species. Furthermore, crosstalk proline with other osmoprotectants signalling molecules, glycine betaine, abscisic acid, nitric oxide, hydrogen sulfide, soluble helps strengthen protective mechanisms stressful environments. Development less temperature-responsive cultivars can be achieved manipulating biosynthesis through genetic engineering. This review presents an overview responses outline under such temperatures.
