The resilience of plants to concurrent abiotic stresses—such as drought, salinity, extreme temperatures, heavy metals, and elevated CO2 levels—is paramount in the era climate change. Reactive oxygen species (ROS), traditionally perceived mere byproducts metabolic processes, serve a dual role: crucial signaling molecules that facilitate plant adaptation deleterious agents causing cellular damage when excessively accumulated. In this review, we highlighted intricate equilibrium maintain through both enzymatic non-enzymatic antioxidant defenses mitigate ROS-mediated oxidative stress, emphasizing sophisticated strategies deploy counteract spectrum combined stresses. Some species, however, exhibit insufficient enhancement their intrinsic counterbalance stress-induced ROS accumulation consequent damage. Consequently, explored pivotal role diverse further strengthening defenses, offering profound insights into bolstering resilience. Furthermore, advent genetic engineering technologies unveils novel avenues for crop improvement, with strategic overexpression genes such SOD, APX, CAT, GPX, DHAR, GR, GST showing immense potential fortifying against challenges imposed by multiple Future perspectives entail deepening our understanding molecular mechanisms governing generation scavenging, investigating synergistic effects co-expressing genes, elucidating interactions between endogenous hormones exogenously applied molecules. We advocate integrative research methodologies, combining field experiments, controlled environmental studies, computational modeling, bridge gap laboratory discoveries practical agricultural applications.

ABSTRACT The increasing frequency of concurrent heat and drought stress poses a significant challenge to agricultural productivity, particularly for cool‐season grain legumes, including broad bean ( Vicia Faba L.), lupin Lupinus spp.), lentil Lens culinaris Medik), chickpea Cicer arietinum grasspea Lathyrus sativus pea Pisum sativum common vetch sativa L.). These legumes play vital role in sustainable systems due their nitrogen‐fixing ability high nutritional value. This review synthesizes current knowledge the impacts tolerance mechanisms associated with combined stresses these crops. We evaluate physiological biochemical responses stress, focusing on detrimental effects growth, development, yield. Key genetic molecular mechanisms, such as roles osmolytes, antioxidants, stress‐responsive genes, are explored. also discuss intricate interplay between signaling pathways, involvement Ca 2+ ions, reactive oxygen species, transcription factor DREB2A, endoplasmic reticulum mediating responses. comprehensive analysis offers new insights into developing resilient legume varieties enhance sustainability under climate change. Future research should prioritize integrating omics technologies unravel plant abiotic stresses.

Functional and transcriptomic characterization of the receptor‐like protein kinase gene GmHSL1b involved in salt stress tolerance in soybean roots

Physiologia Plantarum, Год журнала: 2025, Номер 177(2)

Опубликована: Март 1, 2025

Abstract The survival and adaptation of plants to adverse environmental conditions is crucial facilitated by receptor‐like kinases, which act as cell surface receptors for a variety signals. In this study, we identified gene, GmHSL1b , encoding protein kinase that responsive abscisic acid (ABA) hormonal signals involved in the plant's response drought salt stresses. Subcellular localization assays have demonstrated located plasma membrane. Overexpression gene soybean enhanced root growth development, well tolerance stress, while gmhsl1b mutant revealed increased sensitivity stress. Comparative transcriptome analysis showed some genes associated with various biological processes, such mitogen‐activated (MAPK) cascade signaling, plant hormone wall remodeling, calcium defense mechanisms are differentially expressed overexpressing roots. Our research indicated can regulate expression level candidate aquaporin GmPIP2‐1 thereby affecting water content accumulation reactive oxygen species (ROS) under These findings indicate participates regulating development enhancing thus offering insights boosting crop adaptability

Abstract Drought represents the predominant and most critical abiotic stress challenge within domain of viticulture, necessitating identification application efficacious strategies to ameliorate its deleterious effects. In contemporary realm management, deployment α‐lipoic acid (α‐Lipo), known for antioxidant capabilities, as an exogenous treatment has been investigated mitigating various stresses in numerous plant species, yet a detailed exploration efficacy alleviating drought grapevines remains be conclusively determined. This study aimed elucidate adaptive mechanisms against by examining effects different α‐Lipo concentrations (0, 1, 25 50 μM) applied on foliar under well‐irrigated conditions American grapevine rootstocks ‘1103 P' (drought tolerant) ‘3309 C' sensitive). Our findings revealed that varied significantly depending rootstock type irrigation status. 1103 P treated with 1 μM showed greater positive growth traits, photosynthetic osmotic parameters. contrast, 3309 C same conditions, highest were obtained at concentrations. Under improved physiological parameters (chlorophyll content, proportional water coverage stomatal conductance), proline content enzyme activities (SOD, CAT APX), while reducing electrolyte leakage MDA levels both rootstocks, showing strong potential increase oxidative tolerance sustain growth. Heatmap visualization analysis confirmed data from Principal Component Analysis (PCA) exhibited superior performance compared conditions. indicates importance differences adaptation or uptake efficiency. These suggest holds promise eco‐friendly, natural bio‐stimulant use arid environments, contributing advancement sustainable agricultural practices foreseeable future.

The mulberry (Morus alba L.) tree is an economically and ecologically important perennial woody plant. With climate change, heat, drought stresses have become more frequent intense in growing areas with a strong influence on phenology. However, how perform terms of growth physiological responses under conditions heat combination unknown. Here, we integrated physiological, transcriptomes proteomes profiles to clarify the molecular mechanism combined tolerance mulberry. Six genes included M.alba_G0006903 (HSP21), M.alba_G0008420 (HSP70T-2), M.alba_G0017894 (PPH), M.alba_G0019599 (BAG6), M.alba_G0007122 (MybSt1) M.alba_G0012112 (GT2) were identified as candidate hub both co-expression network PPI network. In total, four modules 195 related drought-heat stress through transcriptome analyses three species (guisangyou12hao, guisangyou62hao yuesang51hao). Using tandem mass tags (TMT)-based proteomics, total 4,558 proteins 1,795 differentially expressed (DEPs) identified. Of these, 1,265 (969 same trend, 296 opposite trend) showed differences expression at transcriptional translational level. Physiological examination reviewed that POD, PRO, MDA accumulated large amounts seedlings stress, indicating accumulation osmoregulatory substances enhancement antioxidant enzyme activities helped limit further damage caused by stress. These studies provide comprehensive understanding underlying gene information theoretical basis for improving breeding future.
