Due to the increasing health and environmental risks associated with use of fungicides in agriculture, alternatives-such as using plant growth-promoting bacteria (PGPB) suppress phytopathogens-that simultaneously improve yield, are important. This study evaluated biocontrol efficiency Bacillus velezensis CE100 against Macrophomina phaseolina Fusarium oxysporum f. sp. fragariae, respective causal agents for charcoal rot fusarium wilt diseases strawberry, its potential enhance strawberry growth fruit production. B. CE 100 produced fungal cell wall-degrading enzymes, chitinases, β-1,3-glucanases; inhibited mycelial M. F. fragariae by 64.7% 55.2%, respectively. The mycelia both phytopathogenic fungi showed severe swelling rupturing hyphae compared smooth, normal control group. Moreover, up 2.8 units/mL indole-3-acetic acid (IAA) during incubation enhanced root biomass strawberries. Consequently, not only increased yield strawberries controlling but also through enhancing growth. findings this indicate that could be a safe, ecofriendly alternative chemical

Plant diseases and insect pest damage cause tremendous losses in forestry fruit tree production. Even though chemical pesticides have been effective the control of plant pests for several decades, they are increasingly becoming undesirable due to their toxic residues that affect human life, animals, environment, as well growing challenge pesticide resistance. In this study, we review potential hydrolytic enzymes from Bacillus species such chitinases, β-1,3-glucanases, proteases, lipases, amylases, cellulases biological phytopathogens pests, which could be a more sustainable alternative pesticides. This study highlights application different sp. biocontrol alternatives against phytopathogens/insect through degradation cell wall/insect cuticles, mainly composed structural polysaccharides like chitins, β-glucans, glycoproteins, lipids. demonstrates prospects applying biopesticides forest production, mode biocidal activity dual antimicrobial/insecticidal potential, indicates great prospect simultaneous pests/diseases. Further research should focus on optimizing production enzymes, synergism facilitate

Bacillus velezensis RC116 Inhibits the Pathogens of Bacterial Wilt and Fusarium Wilt in Tomato with Multiple Biocontrol Traits

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(10), С. 8527 - 8527

Опубликована: Май 10, 2023

Soil-borne plant diseases seriously threaten the tomato industry worldwide. Currently, eco-friendly biocontrol strategies have been increasingly considered as effective approaches to control incidence of disease. In this study, we identified bacteria that could be used agents mitigate growth and spread pathogens causing economically significant plants, such bacterial wilt Fusarium wilt. Specifically, isolated a strain Bacillus velezensis (RC116) from rhizosphere soil in Guangdong Province, China, with high potential confirmed its identity using both morphological molecular approaches. RC116 not only produced protease, amylase, lipase, siderophores but also secreted indoleacetic acid, dissolved organophosphorus vivo. Moreover, 12 maker genes associated antibiotics biosynthesis amplified genome. Extracellular proteins exhibited strong lytic activity against Ralstonia solanacearum oxysporum f. sp. Lycopersici. Pot experiments showed efficacy was 81%, consequently, significantly promoted plantlets. Based on these multiple traits, is expected developed into broad-spectrum agent. Although several previous studies examined utility B. for fungal diseases, few date evaluated diseases. Our study fills research gap. Collectively, our findings provide new insights will aid soil-borne well future strains.
