Introduction Entomopathogenic fungi (EPF) can colonize and establish symbiotic relationships with plants as endophytes. Recently, EPF have been reported to suppress plant pathogens induce resistance diseases. However, the potential mechanisms via which endophytes control major diseases in situ remain largely unknown. Methods Pot field experiments were conducted investigate an EPF, Beauveria bassiana , colonizes tomato, under Botrytis cinerea infection stress. B. blastospores inoculated into tomato by root irrigation. Tomato gray mold caused was evaluated artificial inoculation, colonization rhizosphere soil stress colony counting quantitative PCR. Furthermore, expression levels of three disease resistance-related genes ( OXO CHI atpA ) leaves determined explore effect on performance pot experiments. Results could improve . The incidence rate, lesion diameter, index decreased both following colonization. more likely accumulate pathogen infected leaves, while decreasing soil, induced genes, up-regulated leaves. Discussion results indicated that “recruit” from diseased directional effects, then enhanced growth against pathogens, consequently inhibiting multiplication plants. Our findings provide novel insights enhance our understanding roles during challenge.

Tetranychus urticae is an important pest of tomato crops globally, affecting plant yield and growth. Beauveria bassiana Metarhizium robertsii have the potential to control T. urticae. We investigated influence two B. (i.e., WG-12 WG-19) isolates one M. (WG-02) isolate when colonizing different organs (leaves, stems, roots) their on growth plants, through foliar, root-dipping, seed-soaking application techniques. also examined acaricidal activity three against (female adults), spraying leaf discs with each separately. After 28 days, WG-19 colonized 97 91% leaves after foliar inoculation, whereas WG-02 exhibited lowest colonization (76%). The height root length, number leaves, weight biomass above below ground were enhanced significantly inoculation vs. control. complete mortality was caused by 10 killed 94% adults. For effective management urticae, we propose since it provides protection promotes plants.

Abstract BACKGROUND Piriformospora indica is an endophytic fungus that can promote the growth and confer resistance against diverse stresses in host plants by root colonization. However, effects of P. colonization on improving plant to insect pests are still less explored. The brown planthopper (BPH) Nilaparvata lugens a serious monophagous pest causes extensive damage rice plants. Here, we aimed evaluate BPH. RESULTS roots resisted from Age‐stage, two‐sex life table analyses showed feeding indica‐ colonized affected BPH's female adult longevity, oviposition period, fecundity, population parameters size. BPH adults excreted honeydew. remarkably increased duration np, N2, N3 waveform, as well occurrences N1 decreased N4‐b for Meanwhile, weight was significantly lower than control. In addition, preferences ‐colonized were reduced. qRT‐RCR revealed induced expressions jasmonic acid (JA)‐ salicylic (SA)‐related genes CONCLUSION reduce performance with potential inhibitory growth. Collectively, these results support endophytically effective strategy improve crops. © 2024 Society Chemical Industry.

Entomopathogenic fungi, often acknowledged primarily for their insecticidal properties, fulfill diverse roles within ecosystems. These encompass endophytism, antagonism against plant diseases, promotion of the growth plants, and inhabitation rhizosphere, occurring both naturally upon artificial inoculation, as substantiated by a growing body contemporary research. Numerous studies have highlighted beneficial aspects endophytic colonization. This review aims to systematically organize information concerning direct (nutrient acquisition production phytohormones) indirect (resistance induction, antibiotic secondary metabolite production, siderophore mitigation abiotic biotic stresses) implications Furthermore, thorough discussion these mechanisms is provided. Several challenges, including isolation complexities, classification novel strains, impact terrestrial location, vegetation type, anthropogenic reluctance use fungal entomopathogens, been recognized hurdles. However, recent advancements in biotechnology microbial research hold promising solutions many challenges. Ultimately, current constraints delineate potential future avenues leveraging entomopathogens dual control agents.

Numerous concerns associated with the use of synthetic pesticides have led to important initiatives aimed at ensuring eco-friendly practices in pest and disease control. Third-generation pesticides, biopesticides, become a key factor those efforts, capturing attention researchers worldwide. To evaluate trends biopesticide research over past three decades, bibliometric analysis was performed on bibliographic data sourced from Web Science database. This included metrics such as publication dynamics, types documents, assessments fields categories. Co-authorship, citation, co-occurrence networks were visualized using VOSviewer software identify collaboration patterns, influential publications, emerging topics, interdisciplinary connections. A total 5054 publications topic ‘biopesticide’ found (1994–2024), nearly half which published last five years. Out 136 contributing countries, USA, People’s Republic China, India produced most while 19,676 authors contributed least one paper throughout entire examined period. The identification frequently used keywords highlighted significant topics within biopesticide-related earliest recent, aiding our understanding developmental trajectory opportunities for future exploration.

Entomopathogenic fungi are increasingly used as bio-inoculants to enhance crop growth and resistance. When applied rhizosphere soil, they interact with resident soil microbes, which can affect their ability colonize induce resistance in plants well modify the structure of microbiome, either directly through interactions or indirectly, mediated by plant. The extent such direct versus indirect between microbes impact microbe-induced crops remains unclear. This study uses a split-root system examine effects (plant-mediated) an entomopathogenic fungus, Metarhizium brunneum, on induced tomato against two-spotted spider mites. Additionally, explores how these influence composition diversity fungal bacterial communities. Resident reduced efficacy M. brunneum reduction occurred not only when interacted bio-inoculant but also were spatially separated within root system, indicating plant-mediated effects. inoculation did microbial led changes community composition, even communities contact inoculant. research highlights both bio-inoculant-induced pest underscores importance assessing potential adverse native

The tomato leafminer, Tuta absoluta, is a destructive invasive pest worldwide. Bacillus amyloliquefaciens W10, bacterium isolated from the rhizosphere of tomatoes, classified as plant growth-promoting rhizobacterium. However, whether B. W10 can improve resistance against T. absoluta remains unclear. In this study, we found that promoted growth and significantly reduced fecundity absoluta. To further evaluate effects on tomato’s to age-stage, two-sex life table, oviposition preference test were carried out investigate individual fitness, population parameters, behavior Compared control, intrinsic rate increase (rm), net reproductive (R0), finite (λ) in treatment group reduced, while doubling time (DT) was increased. Meanwhile, preferences for treated plants reduced. After infestation, electrical conductivity hydrogen peroxide (H2O2) content leaves after lower than those peroxidase (POD), polyphenol oxidase (PPO), jasmonic acid (JA), salicylic (SA) levels higher. addition, O2−, superoxide dismutase (SOD), catalase (CAT) also affected. qRT-RCR analyses revealed colonization induced expressions JA- SA-related genes, including AOS1, AOC, PAL1, SAMT, infestation.
