Plant hormones and neurotransmitter interactions mediate antioxidant defenses under induced oxidative stress in plants

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Опубликована: Сен. 9, 2022

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.

By the year 2050, world's population is predicted to have grown around 9-10 billion people. The food demand in many countries continues increase with growth. Various abiotic stresses such as temperature, soil salinity and moisture all an impact on plant growth development at levels of growth, including overall plant, tissue cell, even sub-cellular level. These directly harm plants by causing protein denaturation aggregation well increased fluidity membrane lipids. In addition direct effects, indirect damage also includes synthesis inhibition, breakdown, membranous loss chloroplasts mitochondria.

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.

Plants are very often confronted by different heavy metal (HM) stressors that adversely impair their growth and productivity. Among HMs, chromium (Cr) is one of the most prevalent toxic trace metals found in agricultural soils because anthropogenic activities, lack efficient treatment, unregulated disposal. It has a huge detrimental impact on physiological, biochemical, molecular traits crops, addition to being carcinogenic humans. In soil, Cr exists forms, including (III) "trivalent" (VI) "hexavalent", but pervasive severely hazardous form biota (VI).

Опубликована: Янв. 1, 2022

Cucumber (Cucumis sativus L.), an important vegetable, popular worldwide for its crispy texture and special flavor. Plant hormones such as auxin stands out dominating function in morpho- organogenic processes, formation of organs well regulation tropic responses. These developmental processes are entirely or partially dependent on biosynthesis, transport, signal transduction. In cucumber, not only fine-tunes morphogenesis but also response to environmental stress. The role regulating different (root, hypocotyl, shoot, leaf, tendril, flower, fruit) development cucumber was reviewed the present paper.
