Phenolic compounds, abundant secondary metabolites in plants, profoundly influence soil ecosystems, plant growth, and interactions with herbivores. In this study, we explore the intricate relationships between phenolics, microbes, gall formation Ageratina adenophora (A. adenophora), an invasive species China known for its allelopathic traits. Using metabolomic microbial profiling, significant differences composition metabolite profiles were observed bulk rhizosphere samples. Phenolics influenced bacterial communities, distinct populations enriched each type. Additionally, phenolics impacted metabolic processes, variations Kyoto Encyclopedia of Genes Genomes (KEGG) pathway enrichment analysis different treatments. Analysis phenolic content samples revealed considerable variations, higher concentrations certain tissues types. Bioactive phenols extracted from identified using gas chromatography/mass spectrometry (GC-MS), providing insights into diverse chemical these compounds. Furthermore, effects on growth investigated. Phenols exhibited both stimulatory inhibitory optimal promoting emergence but hindering growth. Gall was by concentrations, leading to structural alterations stem tissue morphology. Histochemical starch lipid accumulation tissues, indicating changes induced phenolics. The presence disrupted structures vascular bundle orientation tissues. Overall, our study highlights multifaceted roles compounds development, formation, facilitating utilization agriculture.

Endophytic Colonization by the Entomopathogenic Fungus Beauveria Bassiana Affects Plant Volatile Emissions in the Presence or Absence of Chewing and Sap-Sucking Insects

Frontiers in Plant Science, Год журнала: 2021, Номер 12

Опубликована: Июль 26, 2021

Entomopathogenic fungi are gaining acceptance in Integrated Pest Management (IPM) systems as effective and environmental safety biological control agents to protect a great variety of crops against pest insects. Many these insect-pathogenic can establish themselves endophytes thereby may induce the plant immune system. The activation defenses by fungal endophytic colonization have direct impact on herbivores pathogens. An integral component many defense responses is also release volatile organic compounds, which serve an indirect attracting natural enemies herbivores. Here we investigated effect entomopathogenic fungus Beauveria bassiana emission melon cotton plants, either unharmed or after being damaged sap-sucking aphids leaf chewing caterpillars. We found that when plants colonized B. they emit different blend compounds compared uncolonized plants. Some emitted been reported previously be released response herbivory implicated enemy attraction. Several known antimicrobial properties. Therefore, might help not only insect pests but increase resistance agronomically important phytopathogens.

Plant–Entomopathogenic Fungi Interaction: Recent Progress and Future Prospects on Endophytism-Mediated Growth Promotion and Biocontrol

Plants, Год журнала: 2024, Номер 13(10), С. 1420 - 1420

Опубликована: Май 20, 2024

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.

Опубликована: Май 5, 2018

The viruses are one of the most threatening factors for plants resulting in gigantic economic losses.These utilize host internal machinery reproduction and can spread through biological non-biological means.Among hazardous plant viruses, Tobacco mosaic virus (TMV) is ancient which causes massive losses to tobacco, pepper, cucumber ornamental crops globally.The problem be reduced by minimizing vector population application pesticides.Opposite obtained success control, rapid utilization synthetic chemicals disastrous our ecosystem.Therefore, alternative approaches such as natural derivatives should explored eco-friendly management TMV.So, here we have tried take into account various metabolites effectively potentially used against TMV.We further explained about from animals, fungi, bacteria actinomycetes useful TMV.The review imbibes recent research findings regarding exploration TMV concludes highlighting future prospects via hoping that pesticides will safer human being planet.

The Endophyte Trichoderma asperellum M2RT4 Induces the Systemic Release of Methyl Salicylate and (Z)-jasmone in Tomato Plant Affecting Host Location and Herbivory of Tuta absoluta

Frontiers in Plant Science, Год журнала: 2022, Номер 13

The use of endophytic fungi has dramatically increased plant performance through the enhancement protection against abiotic and biotic stressors. We previously demonstrated that fungus Trichoderma asperellum M2RT4 improves tomato defenses leafminer Tuta absoluta reduction oviposition, leafmining, pupation, adult emergence. However, underlying mechanism by which presence this within host affects T. selection life-history traits is unknown. tested behavioral responses in Y-tube olfactometer bioassays found females preferred non-inoculated plants those inoculated endophytes. Additionally, were not attracted to infested nor inoculated-infested plants. Chemical analysis revealed emission methyl salicylate an increase amounts monoterpenes emitted from we upon herbivory, modulates chemistry production (Z)-jasmone thus activating both salicylic jasmonic acid defense pathways. Further, monoterpernes including α-pinene, 2-carene, β-phellandrene but repelled salicylate. Methyl could therefore be considered as a good semiochemical-based candidate for sustainable management using "push-pull" approach. dose-response bioassays, did show any preference four component-blend (α-pinene, β-phellandrene, salicylate). (Z)-jasmone-treated leaflets significantly reduced leafmining activity pest at concentration 10 ng/μL causing highest larval mortality rate (83%) with shortest LT50 (1.73 days) 7 days post-treatment. effect on herbivore was then (Z)-jasmone-mediated. These findings expand our understanding how mediate chemical interactions between its are potentially important development environmentally friendly programs.
