Abstract Plants are continually challenged by abiotic stressors, including drought, salinity, and extreme temperatures, which can adversely affect their growth development. The plasma membrane, acting as a pivotal interface between the cell its environment, is particularly susceptible to such stresses. This review focuses on current understanding of how stresses membrane integrity in plants. also explores critical roles proteins lipids under stress conditions, highlighting signal transduction pathways that initiates mitigate stress. By consolidating these findings, this provides comprehensive overview for advancing development stress-tolerant plant varieties. insights gained from synthesis expected contribute significantly enhancement resilience face environmental challenges.

Acetic acid (HAC) is a crucial signal molecule in plant stress responses; however, its role conferring heat tolerance to rice remains unclear. This study aims investigate the effect of HAC protecting pistil function under and potential facilitating pollen germination tube growth via HAC-induced synthesis methyl jasmonate (MeJA) quercetin (QR). Physiological analysis, including germination, into ovule, reactive oxygen species (ROS), as well levels HAC, acetyl coenzyme A (acetyl-CoA), MeJA, QR pistils stress-treated early indica cultivars Zhongzao39 (ZZ39) Zhongjiazao17 (ZJZ17), were conducted. RNA sequencing (RNA-seq) was performed identify differentially expressed genes involved this process. Effect exogenous acetate (NaAC), on spikelet fertility also investigated. Compared with ZJZ17, severe inhibition fertility, observed ZZ39, due ROS burst an irregular distribution across stigma, style, ovule. RNA-seq physiological data indicate that may activate acetyl-CoA enhance by inducing MeJA QR. Exogenous NaAC enhanced stress, accompanied elevated antioxidant enzyme activities, improved energy status, increased acetyl-CoA, pistils. Additionally, NaAC, QR, either alone or combination, effectively augmented while combination inhibitors significantly reduced fertility. Acetate activates induce both thereby alleviating heat-induced dysfunction maintaining homeostasis enhancing Our results offer promising strategy crops.

Abstract In recent years, abiotic stresses, including droughts, floods, high temperatures, and salinity, have become increasingly frequent severe. These stresses significantly hinder crop yields product quality, posing substantial challenges to sustainable agriculture global food security. Simultaneously, the rapidly growing population exacerbates need enhance production under worsening environmental conditions. Consequently, development of effective strategies strengthen resilience plants against water scarcity, extreme conditions is critical for mitigating impacts stress. Plants respond these by reprogramming their transcriptome metabolome. Common developing stress-tolerant include screening germplasm, generating transgenic plants, employing genome editing techniques. Recently, chemical treatment has emerged as a promising approach stress tolerance in crops. This technique involves application exogenous compounds that induce molecular physiological changes, thereby providing protective shield Forward reverse genetic approaches facilitated identification chemicals capable modulating plant responses stresses. priming agents function epigenetic regulators, agonists, or antagonists, playing essential roles regulating stomatal closure conserve water, managing cellular signaling through reactive oxygen species metabolites sustain growth, activating gluconeogenesis metabolism. review summarizes advancements field explores improve productivity, contributing enhancement

The plant parasitic root-knot nematodes of the species Meloidogyne incognita infect many cultivated plants, one which is tomato (Solanum lycopersicum). To be fed, M. selects unique feeding sites inside root and induces formation large galls (knots) encompassing so-called giant cells (GCs). In present study, a comparative analysis GCs/root cell wall components between incognita-infected uninfected plants pre-treated with biostimulant nematicide acetic acid (AA) was carried out. Pectin, hemicellulose extensin epitopes were detected in sections. incognita-induced GCs roots had walls arabinans, unesterified/methylesterified homogalacturonans xyloglucans, but devoid mannans extensins. Interestingly, above epitope distribution also differed sections made near formed knot, proximal to cap. Moreover, it seemed that AA able induce deposition extensins AA-treated, incognita-uninfected hamper GC development roots. According AA, stimulates natural defense mechanisms tomato, thus protecting from nematode infestation.
