摘要

干旱是一种限制植物生长和降低作物产量的环境制约因素，尤其影响地中海地区的硬粒小麦种植。本研究探讨了不同硬粒小麦基因型对干旱胁迫的适应机制。综合分析发现了区分基因型对干旱反应的显著标记，揭示了增强耐旱性的性状之间复杂的相互作用。值得注意的是，鉴定出14个反映干旱效应的标记和16个与基因型变异相关的标记。该分析根据其耐旱性和代谢动力学将基因型分为不同的组。耐受性基因型，包括BULEL、SVEVO和SVEMS16，在干旱条件下表现出较低的可塑性和稳定的性能，采用独特的策略，如增强离子稳态、应激响应基因调控（如TdDHN15.3）和脂质调节。SVEMS1通过补偿机制表现出耐受性，而老品种（S.CAP， ETRUSCO）则表现出共同的脆弱性，包括营养吸收中断和胁迫信号减少。总体而言，本研究阐明了多种性状在干旱适应中的相互作用，为培育抗旱性强的小麦基因型提供了关键标记，以增强缺水地区的粮食安全。

Integrating ionomics and targeted metabolomics to identify key markers of drought responses in durum wheat (Triticum durum Desf.) genotypes

Drought is an environmental constrains limiting plant growth and reduce crop yield, particularly impacting durum wheat cultivation in the Mediterranean region. This research examined the adaptive mechanisms employed by various durum wheat genotypes in response to drought stress conditions. A comprehensive analysis identified significant markers that differentiate the genotypes' responses to drought, revealing a complex interaction of traits that enhance drought tolerance. Notably, 14 markers reflecting drought effects and 16 markers associated with genotype variations were identified. The analysis categorized the genotypes into distinct groups based on their tolerance to drought and metabolic dynamics. The tolerant genotypes, including BULEL, SVEVO, and SVEMS16, demonstrate lower plasticity and stable performance under drought, employing unique strategies such as enhanced ion homeostasis, stress-responsive gene regulation (e.g., TdDHN15.3), and lipid adjustments. SVEMS1 displayed tolerance through compensatory mechanisms, while older varieties (S.CAP, ETRUSCO) showed shared vulnerabilities, including disrupted nutrient uptake and reduced stress signaling. Overall, this research elucidates the interplay of multiple traits in drought adaptation, offering key markers for breeding resilient wheat genotypes to enhance food security in water-limited regions.

期刊介绍： The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
