Salinity stress significantly threatens seed germination, plant growth, and agricultural productivity, necessitating effective mitigation strategies. This study evaluates the potential of salicylic acid (SA) pretreatment to alleviate detrimental effects salinity on common bean (Phaseolus vulgaris) genotypes. SA, a phenolic hormone, is crucial for regulating responses, essential physiological processes, including germination ion transport. Previous research has established general benefits SA in enhancing tolerance, but specific mechanisms genotypes remain underexplored. focuses impact seedling growth various genotypes, efficacy these genotypes' tolerance stress, underlying biochemical mechanisms, particularly involving antioxidant defense system. The was conducted two phases: growth. Ten commercial varieties were exposed varying levels alongside concentrations assess performance. Subsequently, six one variety evaluated under controlled salt conditions (100 mM 200 NaCl), with treatments at 0, 0.5, 1 mM. Results revealed that severely impaired traits, which enhanced by pretreatment. During phase, resulted reduced protein, chlorophyll, carotenoid content, decreased potassium (K⁺) levels, diminished water while increasing electrolyte leakage, malondialdehyde (MDA) sodium (Na⁺) concentrations, enzyme activities, proline levels. Importantly, elevated chlorophyll protein improved retention, moderated K⁺ Na⁺ their ratios conditions. also system, reducing oxidative damage induced stress. Principal component analysis (PCA) successfully categorized into semi-tolerant, tolerant, semi-sensitive, sensitive classes based responses. Notably, Jules exhibited exceptional resilience during both stages, indicating its as superior candidate cultivation salt-affected regions. highlights an strategy enhance novelty this work lies detailed elucidation SA's role modulating defenses homeostasis different providing new insights breeding programs practices aimed improving crop productivity increasingly saline environments.

Salinity is one of the main abiotic stresses that limits plant growth. This study addressed how composition and diversity root-associated bacterial communities reacts over time to salt-induced stress conditions. To understand its adaptation soil salinization, microbiome was studied by total DNA extraction sequencing, using Illumina MiSeq platform. Additionally, we evaluated metabolites associated with salt (oxylipins, fatty acids (FAs) hormones) mass spectrometry. reduced rhizosphere in salt-treated plants at 7 14 days triggered a progressive shift structure, starting after imposed. The community became enriched specific bacteria potential genes involved PGP trait ion homeostasis. For these plants, showed higher levels included 9-lipoxygenase (LOX) oxylipins, which were found 14. results indicated salinity seems have induced changes community, characteristics may help respond imposed stress. Furthermore, our highlighted role 9-LOX oxylipins responding stress, providing new insights into complex plant–microbe interactions under

Water scarcity has affected much of Chile for the past 15 years, and Amelichloa caudata, a native species adapted to arid conditions, may offer solution. The hypothesis this study is that both acetylsalicylic acid (ASA) biosolids (BSs) can positively influence plant growth under water stress. This assessed effects ASA BSs on edaphic, physiological, biochemical, productive parameters A. caudata conditions. Results showed treatments enhanced biomass production, height, leaf number, canopy weight. improved retention, mitigating stress leading levels comparable controls. In contrast, did not show significant benefits had lowest values all highest root dry weight was observed in water-restricted plants, while ASA-treated plants lower malondialdehyde (MDA) levels, indicating reduced oxidative However, BS treatment increased MDA suggesting more severe damage. Despite improvements high salt concentrations limit their effectiveness further research required optimize application rates.
