Plants are constantly exposed to various phytopathogens such as fungi, Oomycetes, nematodes, bacteria, and viruses. These pathogens can significantly reduce the productivity of important crops worldwide, with annual crop yield losses ranging from 20% 40% caused by pathogenic diseases. While use chemical pesticides has been effective at controlling multiple diseases in major crops, excessive synthetic chemicals detrimental effects on environment human health, which discourages pesticide application agriculture sector. As a result, researchers worldwide have shifted their focus towards alternative eco-friendly strategies prevent plant Biocontrol is less toxic safer method that reduces severity A variety biological control agents (BCAs) available for use, but further research needed identify potential microbes natural products broad-spectrum antagonistic activity This review aims highlight importance biocontrol managing Furthermore, role beneficial current status mechanisms will be summarized.

Over the past four decades, Bacillus biofertilizers, which are microbial formulations based on species, have significantly contributed to sustainable agriculture by enhancing crop growth, improving soil health, and reducing dependency chemical fertilizers. particularly known for their ability promote plant fix nitrogen, solubilize phosphorus, produce growth-promoting substances such as phytohormones antibiotics, emerged key players in development of eco-friendly agricultural solutions. This research utilizes bibliometric analysis 3,242 documents sourced from Web Science database map development, contributions, innovation within field 1985 2023. study identifies exponential growth output, 2003 onwards, indicating a robust interest expanding base predominantly China, India, United States. We segmented timeline into three distinct phases, each marked varying rates foci. paper presents novel insights geographical institutional distributions research, highlighting predominant role developing countries advancing Bacillus-based technologies. Key hotspots evolved basic applications complex interactions involving synthetic communities advanced multi-omics techniques. Our findings demonstrate trend towards more strategic technologically integrated approaches reflecting broader shifts systems. not only charts historical progress, but also proposes future trajectories aimed at application effectiveness fertilizers across diverse ecosystems.

The role of Bacillus species in the management of plant-parasitic nematodes

Frontiers in Microbiology, Год журнала: 2025, Номер 15

Опубликована: Янв. 17, 2025

Plant-parasitic nematodes (PPNs), including root-knot (Meloidogyne spp.), cyst (Heterodera and Globodera other economically significant nematode species, pose severe threats to global agriculture. These employ diverse survival strategies, such as dormancy in cysts or robust infective juvenile stages. Consequently, their management is challenging. Traditional control methods, the use of chemical nematicides, are increasingly scrutinized because environmental health concerns. This review focuses on specific mechanisms employed by Bacillus spp., nematicidal compound production, systemic resistance induction, cuticle degradation, target nematodes. offer sustainable solutions for managing promoting soil enhancing microbial diversity nutrient cycling. An integrated approach leveraging Bacillus-based biocontrol proposed maximize efficacy agricultural sustainability.

Drought stress hampers plant growth and productivity. Some microorganisms mitigate in plants; however, the molecular mechanism by which they interact with plants mitigating remains unknown. This study aimed to determine growth–promoting rhizobacteria modulate drought soybean. Results indicated that B. pumilus SH-9 (SH-9) produced indole acetic acid siderophore, had capacity for phosphate solubilization. The test polyethylene glycol 6000 (PEG) tolerance, showed could withstand high PEG concentration (up 30%). isolate was identified a strain using 16s ribosomal DNA gene sequence. Inoculation of soybeans enhanced soybean biomass 20%, even under stress. due reduction endogenous phytohormone (abscisic acid) upregulation antioxidant defense system (SOD, POD, APX, GSH) SH-9. Furthermore, transcription factors GmDREB2, GmbZIP1, GmNCED3 were involved. also improved physio-morphological characteristics such as biomass, chlorophyll, seedling length, relative water contents stressed plant. Overall, findings this enhances promoting solubilization, exopolysaccharides. We, therefore, conclude is drought-tolerant variant can improve via modulation expression gene, profile.

HighlightsCyclic lipopeptides (CLPs) represent unique bacterial natural products with an amazing chemical diversity driving multiple potent bioactivities.More than just lubricants, solubilizers or killing agents, CLPs retain unsuspected array of functions and feature as private tools shared goods produced on demand.Resolving the molecular rules CLP selectivity for a given function requires combined expertise in biology, structural chemistry, biophysics to comprehensively understand their intricate interactions biological membranes.Discovering new should exploit multilevel microbial involve recent advances metagenomics, genome mining, community metabolomicsDeciphering ultimate proximate aspects lipopeptide science highlights relevance ecology.AbstractMicrobial are widely explored therapeutic potential. Understanding underlying evolutionary adaptive forces production remains fundamental question biology. Amphiphilic cyclic (CLPs), prominent category specialized metabolites, show strong antimicrobial activity, particularly against phytopathogens. It is thus assumed that these compounds deployed by soil- rhizosphere-dwelling bacteria weapons competitive environments. Here, we challenge this reductionist perspective present evidence Bacillus mediators ecological interactions.

Опубликована: Сен. 30, 2024

The significant reduction in agricultural output and the decline product quality are two of most glaring negative impacts caused by plant pathogenic fungi (PPF). Furthermore, contaminated food or transit might introduce mycotoxins produced PPF directly into chain. Eating tainted with mycotoxin is extremely dangerous for both human animal health. Using fungicides first choice to control their toxins food. Fungicide resistance its effects on environment public health becoming more a concern, despite fact that chemical used limit toxicity growth crops. Fungicides induce target site alteration efflux pump activation, mutations result resistance. As result, global trends shifting away from chemically manufactured pesticides toward managing fungal diseases using various biocontrol techniques, tactics, approaches. However, surveillance programs monitor fungicide environmental impact much fewer compared bacterial antibiotic programs. In this review, we discuss contributes disease development plants, against them, factors causing spread emergence new strains, antifungal mechanisms PPF, health, fungicides, use agents (BCAs), antimicrobial peptides (AMPs), nanotechnologies as safe eco-friendly alternative fungicides.
