Published: March 15, 2025

Transcription factors are extensively found in fungi and involved the regulation of multiple biological processes, including growth, development, conidiation, morphology, stresses tolerance, virulence, as well production secondary metabolites. Biocontrol is a complex process through which several biocontrol behaviors, such secretion cell wall-degrading enzymes metabolites, regulated by transcription factors. To date, biocontrol-related have been reported fungi, Beauveria bassiana, Clonostachys rosea, Coniothyrium minitans, different species genera Metarhizium, Trichoderma, Arthrobotrys. However, comprehensive reviews summarizing analyzing with potential these scarce. This review begins giving basic overview their functions. Then, role discussed. Lastly, possible approaches for further work on suggested. provides basis elaborating molecular mechanisms context biocontrol.

Abstract Crocidolomia pavonana , commonly known as the cabbage cluster caterpillar, is a significant pest of plants, causing substantial damage and economic losses. One potential method to control C. using entomopathogenic fungus Trichoderma asperellum . This study aimed identify most effective isolate T. in managing populations. Four isolates were evaluated: SD324, SD327, A116, AB2B3, with conidial density 10 8 conidia/ml. The suspensions applied second instar larvae Observations included larval mortality, percentage pupation, adult emergence, pre-oviposition, oviposition, post-oviposition periods female adults, number egg batches. Data analyzed analysis variance (ANOVA) followed by 5% LSD test. Results indicated that all demonstrated controlling larvae, highest mortality rate (93.33%) observed A116. Additionally, application inhibited pupation (6.67%), emergence (10%), inhibition life cycle development.

Synthesis of Extracellular L-lysine-α-oxidase along with Degrading Enzymes by Trichoderma cf. aureoviride Rifai VKM F-4268D: Role in Biocontrol and Systemic Plant Resistance

Journal of Fungi, Journal Year: 2024, Volume and Issue: 10(5), P. 323 - 323

Published: April 28, 2024

When cultivating on wheat bran or deactivated fungal mycelium as a model of “natural growth”, the ability Trichoderma to synthesize extracellular L-lysine-α-oxidase (LysO) simultaneously with cell-wall-degrading enzymes (proteases, xylanase, glucanases, chitinases, etc.), responsible for mycoparasitism, was shown. LysO, in turn, causes formation H2O2 and pipecolic acid. These compounds are known be signaling molecules play an important role induction development systemic acquired resistance plants. Antagonistic effects LysO have been demonstrated against phytopathogenic fungi Gram-positive Gram-negative bacteria dose-dependent cell death. The antimicrobial effect decreased presence catalase. generating intracellular ROS also shown both fungi, which led decrease viable cells. results suggest that activity is due two factors: exogenous hydrogen peroxide product enzymatic oxidative deamination L-lysine direct interaction wall micro-organisms. Thus, its own enhances potential producer environment; namely, enzyme complements strategy fungus biocontrol indirectly participates inducing SAR regulating relationship between pathogens

Mycology&#58 An International Journal on Fungal Biology, Journal Year: 2024, Volume and Issue: 16(1), P. 180 - 209

Published: March 18, 2024

Trichoderma spp. are globally distributed and considered significant fungal resources. This study presents the discovery of 11 new species Trichoderma: T. caeruleum, gongcheniae, graminicola, graminis, hongkuii, parapeberdyi, neoguizhouense, neohongkuii, parahamatum, parahongkuii, shaanxiensis. All these were isolated from soils, except for which found as endophytes in Poaceae plants. The phylogenetic position novel was determined by analysing concatenated sequences second largest nuclear RNA polymerase subunit encoding gene (rpb2) translation elongation factor 1-alpha (tef1). results analysis revealed that each formed a distinct lineage: shaanxiensis belong to Harzianum Clade, neohongkuii members Koningii parahamatum belongs Hamatum caeruleum does not fall within any named clades. also provided detailed description morphology cultural characteristics newly discovered species. contributes advancement knowledge about resources China.

The Use of Bacteria, Actinomycetes and Fungi in the Bioprotection of Solanaceous Crops against Tobacco Mosaic Virus (TMV)

Agriculture, Journal Year: 2024, Volume and Issue: 14(8), P. 1220 - 1220

Published: July 24, 2024

Tobacco mosaic virus (TMV) is one of the most persistent and infectious plant viruses. The substantial economic losses caused by TMV in production tobacco vegetables (especially Solanaceae family) are prompting introduction innovative solutions that effectively inhibit infection this pathogen. Biological control agents based on bacteria genera Pseudomonas, Bacillus, Pantoea actinomycetes becoming increasingly popular fight against TMV. Some fungi, including Fusarium spp., Trichoderma Alternaria spp. Sepedonium as well wood-rotting also exhibit high anti-TMV activity. This article presents a comprehensive review recent scientific advances bioprotection selected solanaceous crops It provides information structure virus, its host range, pathogenicity severity pepper, tomato production. characterises environmentally safe techniques involving biological naturally occurring environment bioactive compounds extracted from them. identifies their effects at morphological, physiological molecular levels.

Phosphorus fertilizer responsive bacteria and fungi in canola (Brassica napus L.) roots are correlated with plant performance

Published: Sept. 12, 2024

Background Canola (Brassica napus L.) has high phosphorus demand, but its seedlings are sensitive to seed-placed fertilizers. Optimizing fertilizer managements (rates and placements) for canola is critical can be aided by a better understanding of the root-associated microbiome, as it plays key roles in improving availability through mineralization solubilization. Methods We conducted two-year field experiment applying monoammonium phosphate fertilizers at three rates (no addition, recommended, 0, 17, 32 kg P ha^{− 1} year^{− 1}) using two opener placements (narrow 2.5 cm vs. wide 10 cm) which affect seedbed concentration phosphorus. performance was evaluated, rhizosphere root bacterial fungal microbiomes were profiled DNA amplicon sequencing. Results High-rate near-seed placement (32 opener) consistently reduced seedling emergence not biomass yield, higher 2020 than 2019. Yearly variations plant growth stages impacted both microbiomes, while fertilization only affected microbiome. Specifically, enriched genera Burkholderia-Caballeronia-Paraburkholderia, Luteibacter, Amaurodon, Trichoderma, Penicillium. Conversely, Chryseobacterium, Chitinophaga, Flavobacterium Olpidium more prevalent roots without addition. yield positively correlated with abundance Burkholderia-Caballeronia-Paraburkholderia Trichoderma roots. Conclusions Phosphorus germination seed yield. Profiling phosphorus-responsive bacteria fungi suggests that have lasting impact on modulating responses soil availability.
