Diversity, Год журнала: 2023, Номер 15(3), С. 457 - 457

Опубликована: Март 19, 2023

Food losses, defined as a reduction in the quantity and quality of food during production storage, impact safety security. Losses caused by plant pathogens are among most significant. Chemical pesticides have been extensively used to prevent microbial diseases. Their toxicity reduced efficacy, however, encouraged investigators develop alternatives. Alternatives based on biopesticides tend be safer more environmentally benign than conventional pesticides. In recent years, formulations progressively increased number diversity attracted commercial interest. Understanding mechanisms which control disease is fundamental achieving optimal control. Biocontrol can divided into two main categories: those related ability inhibit or their virulence factors, that enhance host fitness induce resistance. Here, first type strategy reviewed, directly mediated physical contact between biocontrol agents indirectly exposure pathogen antimicrobial microbial-inhibiting compounds produced antagonist. Mechanisms involving include mycophagy, destruction pathogenic bacteria bacteriophages predation, inhibition topical applications specific dsRNA. Indirect do not involve direct with compounds, competition, factor suppression quorum quenching. These topics reviewed discussed.

Antimicrobial metabolites produced by the plant growth-promoting rhizobacteria (PGPR): Bacillus and Pseudomonas

Advanced Agrochem, Год журнала: 2024, Номер 3(3), С. 206 - 221

Опубликована: Июль 25, 2024

Plant growth-promoting rhizobacteria (PGPR) such as Bacillus and Pseudomonas have drawn broad attention interest due to their agricultural benefits. One of the major benefits PGPR lies at biocontrol capabilities against various plant pathogens. The capability is closely related its producing kinds antimicrobial substances. Major secondary metabolites secreted by include non-ribosomal lipopeptides (NRLPs), polyketides, ribosomal peptides, phenazines, pyrrolnitrins, etc. This review focuses on produced including classifications, structures, mechanisms action genetic regulations. We also discussed applications in provided insights into future development improved strains using synthetic biology approaches.

Plant and microbial features governing an endophytic lifestyle

Current Opinion in Plant Biology, Год журнала: 2023, Номер 76, С. 102483 - 102483

Опубликована: Ноя. 5, 2023

Beneficial microorganisms colonizing internal plant tissues, the endophytes, support their host through growth promotion, pathogen protection, and abiotic stress alleviation. Their efficient application in agriculture requires understanding of molecular mechanisms environmental conditions that facilitate planta accommodation. Accumulating evidence reveals commensal employ similar colonization strategies as pathogenic counterparts. Fine-tuning immune response, motility, metabolic crosstalk accounts for differentiation. For a holistic perspective, experiments with microbial collections comprehensive genome data exploration are crucial. This review describes most recent findings on factors involved endophytic processes, focusing bacteria fungi, discusses required methodological approaches to unravel relevance within community context.

Biological Guardians: Unveiling Microbial Solutions to Combat Cannabis sativa Fungal Pathogens

Stresses, Год журнала: 2025, Номер 5(1), С. 16 - 16

Опубликована: Фев. 17, 2025

Cannabis (Cannabis sativa L.) is one of the earliest cultivated crops and valued for its medicinal compounds, food, fibre, bioactive secondary metabolites. The rapid expansion cannabis industry has surpassed development production system knowledge. scientific community currently focuses on optimising agronomic environmental factors to enhance yield quality. However, cultivators face significant challenges from severe pathogens, with limited effective control options. principal diseases include root rot, wilt, bud powdery mildew, stunt disease, microorganisms that reduce post-harvest Sustainable management strategies involve utilising clean planting stocks, modifying conditions, implementing sanitation, applying fungal bacterial biological agents, drawing decades research other crops. Plant–microbe interactions can promote growth regulate metabolite production. This review examines recent literature pathogen in indoor using biocontrol agents. Specific morphological, biochemical, characteristics hinder implementation cannabis. Subsequent investigations should focus elucidating plant–microbe essential effectiveness methodologies cultivation systems.

Understanding bud rot development, caused by Botrytis cinerea, on cannabis (Cannabis sativa L.) plants grown under greenhouse conditions

Botany, Год журнала: 2023, Номер 101(7), С. 200 - 231

Опубликована: Май 24, 2023

Botrytis cinerea is a widespread necrotrophic plant pathogen that causes diseases on >1000 species, including vegetables and ornamental greenhouse crops. On cannabis ( Cannabis sativ L.), the responsible for causing “bud rot”, major disease affecting inflorescences (compound flowers), as well seedling damping-off leaf blight under certain conditions. During cultivation, can destroy rapidly optimal relative humidity conditions (>70%) moderate temperatures (17–24 °C). Little currently known about host–pathogen interactions of cannabis. Information gleaned from other hosts provide valuable insights comparative purposes to understand development, epidemiology, pathogenicity This review describes pathogenesis host responses infection assesses potential mechanisms involved in resistance. The effects microclimatic environmental strategies early detection using prediction models, application biological control agents prevent development are discussed. Other management approaches reduce impact bud rot also reviewed. Numerous opportunities conducting additional research better cannabis– interaction identified.

Microbial interactions, which regulate the dynamics of eco- and agrosystems, can be harnessed to enhance antagonism against phytopathogenic fungi in agriculture. This study tests hypothesis that plant growth-promoting rhizobacteria (PGPR) also potential biological control agents (BCAs). Antifungal activity assays potentially were caried out using cultures cell-free filtrates nine PGPR strains previously isolated from agricultural soils. Cultures Bacillus sp. BS36 inhibited growth Alternaria AF12 Fusarium AF68 by 74 65%, respectively. Cell-free same strain both 54 14%, Furthermore, co-cultivation with Pseudomonas BS95 target improved their antifungal activity. A subsequent metabolomic analysis Fourier-transform ion cyclotron resonance mass spectrometry (FTICR-MS) identified fengycin- surfactin-like lipopeptides (LPs) filtrates, could explain The co-production multiple families LPs is an interesting feature practical applications.
