Climate change has increased variable weather patterns that affect plants. To address these issues, we developed a microbial biocontrol agent against drought stress in kimchi cabbage (Brassica rapa L. subsp. pekinensis). We selected three bacterial strains (Leifsonia sp. CS9, Bacillus toyonensis TSJ7, and Lysinibacillus capsici TT41) because they showed survival rate of up to 50% good growth when treated with 30% PEG 6000. The were confirm their enhanced resistance under non-watering conditions. Among the strains, TT41 group significant increase various plant parameters compared negative control on 7th day. performed extensive profiling primary secondary metabolites from strain. Multivariate pathway analyses revealed only clustered well-watered almost same metabolome When TT41, lactic acid was identified as an indicator metabolite significantly improved tolerance. Furthermore, treatment effectively induced tolerance cabbage, similar achieved

Plants select microorganisms from the surrounding bulk soil, which act as a reservoir of microbial diversity and enrich rhizosphere microbiome that helps in growth stress alleviation. use organic compounds are released through root exudates to shape microbiome. These various spectrums technically gear interplay between plants world. Although naturally produce influence world, numerous efforts have been made boost efficiency addition compounds. Despite further crucial investigations, synergistic effects beneficial bacteria combinations reported. In this review, we examine relationship determining plant biotic abiotic We investigate molecular mechanism biochemical responses compounds, discuss modifications alleviation done with help bacteria. then exhibit both components highlight future research directions dwell on how engineering metagenomic approaches could be utilized enhance microbes

Detection and characterization of micro‐ and nano‐plastics in wastewater: Current status of preparatory & analytical techniques

Environmental Quality Management, Год журнала: 2024, Номер 34(2)

Опубликована: Май 29, 2024

Abstract Micro‐ and nano‐plastics (MNPs) are ubiquitous emerging pollutants that have gained global traction due to their persistent nature potential risks the environment human health. The physico‐chemical properties of MNPs such as size, shape, density, surface charge hydrophobicity quite different from macro‐plastics, which render them unique behavior exemplified by high rate diffusion, mobility, easy uptake organisms, toxicity, bioaccumulation. Human exposure causes serious health impacts including apoptosis, necrosis, inflammation, oxidative stress, metabolic disorders, hampered immune responses. hazardous persistence in necessitates accelerated studies focused upon detection, quantification, impact analysis, risk assessment. All kinds wastewaters whether municipal, agricultural, or industrial, consist significant loads act secondary source MNP pollution groundwater soil. Wastewater is highly complex composition there several impediments accurate detection identification this matrix owing in‐efficient sampling methods, lack standardized methodologies, non‐reproducibility data. This review provides an overview currently available techniques for sampling, identification, characterization wastewater. A critical commentary on challenges limitations these has been given strategic combinatorial methods suggested efficient reliable analysis wastewater samples. article also highlights novel sensor‐based enabling rapid

Symbiotic Synergy: Unveiling Plant-Microbe Interactions in Stress Adaptation

Deleted Journal, Год журнала: 2024, Номер 77(1)

Опубликована: Дек. 20, 2024

Amidst escalating climate challenges, understanding microbe-mediated plant growth regulation and stress resilience is pivotal for sustainable agriculture. Non-pathogenic microbes, which reside in the phyllosphere, rhizosphere, as endophytes or epiphytes, play crucial roles enabling plants to withstand climate-induced stresses such extreme temperatures, drought, salinity, shifting pathogen dynamics. These microbial symbionts enhance nutrient availability, alter physiological responses, contribute significantly adaptive metabolism health. This review delves into multifaceted interactions between focusing on biochemical enzymatic exchanges that govern immune responses defense signaling under environmental stresses. Recent research highlights plant-associated microbes a 'second functional genome,' diverse structure function, essential resilience. We critically examine contributions alleviating abiotic stressors, highlighting factors diversity, ecosystem compatibility, role of synthetic consortia climate-adapted The emergence novel pathogenic strains due fluctuations mitigating these threats are also discussed. Furthermore, we assess potential axenic cultures enhancing fluctuating environments, while acknowledging gap controlled lab findings broader field applications. Concluding with integrating multi-omic approaches, this underscores importance unraveling complex plant-microbe develop strategies supporting resilient climate-adaptive agricultural systems.
