The guts of insect pests are typical habitats for microbial colonization and the presence bacterial species inside gut confers several potential advantages to insects. These bacteria located symbiotically digestive tracts insects help in food digestion, phytotoxin breakdown, pesticide detoxification. Different shapes chemical assets gastrointestinal have a significant impact on structure makeup population. number communities system differs owing varying shape composition tracts. Due their short generation times rapid evolutionary rates, can develop numerous metabolic pathways adapt diverse ecological niches. In addition, despite hindering insecticide management programs, they still biotechnological uses, including industrial, clinical, environmental uses. This review discusses prevalent associated with guts, mode symbiotic interaction, role resistance, various other biological significance, along knowledge gaps future perspectives. practical consequences microbiome its interaction host may lead encountering mechanisms behind evolution resistance

Effects of microbial biocontrol agents on tea plantation microecology and tea plant metabolism: a review

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 20, 2025

The quality of fresh tea leaves is crucial to the final product, and maintaining microbial stability in plantations essential for optimal plant growth. Unique communities play a critical role shaping flavor enhancing resilience against biotic stressors. Tea production frequently challenged by pests diseases, which can compromise both yield quality. While stress generally has detrimental effects on plants, it also activates defense metabolic pathways, leading shifts communities. Microbial biocontrol agents (MBCAs), including entomopathogenic antagonistic microorganisms, present promising alternative synthetic pesticides mitigating these stresses. In addition controlling MBCAs influence composition communities, potentially health resilience. However, despite significant advances laboratory research, field-level impacts microecology remain insufficiently explored. This review provides insights into interactions among insects, offering strategies improve pest disease management plantations.

Trichoderma- from lab bench to field application: Looking back over 50 years

Frontiers in Agronomy, Journal Year: 2022, Volume and Issue: 4

Published: Oct. 3, 2022

Biological control of plant pathogens has become increasingly possible with the use fungi, which have a high reproductive rate (both sexually and asexually) short generation time are very specific to their target. Trichoderma species found in diverse habitats experience various interactions other organisms. They used as bio-fungicides owing plant-protecting abilities, they produce large number secondary metabolites (SMs) accompanied by enrichment metabolism-associated genes. This article aims review discuss SMs produced species, including physiology, mode action, mass production, industrial field applications for diseases. We also evolutionary history, taxonomical gradient, classification, ecology well indirect direct mechanisms protectors gene improvement strategies. Aside from bioactivity derived compatibility fungicides, formulation techniques, focuses on its advent progress global research pioneer.

Understanding and exploring the diversity of soil microorganisms in tea (Camellia sinensis) gardens: toward sustainable tea production

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: April 12, 2024

Leaves of Camellia sinensis plants are used to produce tea, one the most consumed beverages worldwide, containing a wide variety bioactive compounds that help promote human health. Tea cultivation is economically important, and its sustainable production can have significant consequences in providing agricultural opportunities lowering extreme poverty. Soil parameters well known affect quality resultant leaves consequently, understanding diversity functions soil microorganisms tea gardens will provide insight harnessing microbial communities improve yield quality. Current analyses indicate garden soils possess rich composition diverse (bacteria fungi) which bacterial Proteobacteria, Actinobacteria, Acidobacteria, Firmicutes Chloroflexi fungal Ascomycota, Basidiomycota, Glomeromycota prominent groups. When optimized, these microbes’ function keeping ecosystems balanced by acting on nutrient cycling processes, biofertilizers, biocontrol pests pathogens, bioremediation persistent organic chemicals. Here, we summarize research activities (tea garden) as biological control agents bioremediators health quality, focusing mainly members. Recent advances molecular techniques characterize examined. In terms viruses there paucity information regarding any beneficial gardens, although some instances insect pathogenic been pests. The potential reported here, recent study their genetic manipulation, aimed at improving for production.

Diversity in rhizospheric microbial communities in tea varieties at different locations and tapping potential beneficial microorganisms

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: Nov. 10, 2022

Soil microenvironments and plant varieties could largely affect rhizosphere microbial community structure functions. However, their specific effects on the tea are yet not clear. Beneficial microorganisms important groups of communities that hold ecological functionalities by playing critical roles in disease resistance, environmental stress tolerance. Longjing43 Zhongcha108 two widely planted China. Although shows higher resistance than Longjing43, potential role beneficial microbes is unknown. In this study, function these were compared using Illumina MiSeq sequencing (16S rRNA gene ITS) technologies. Rhizosphere soil was collected from four independent gardens distributed at locations Hangzhou Shengzhou cities eastern China, both separate gardens. Significant differences physicochemical properties as demonstrated ANOVA PCA, distinct multiple-biotech analyses (PCoA, LEfSe, Co-occurrence network analyses) between (p < 0.01) found. Functions bacteria annotated FAPROTAX database, a abundance Nitrososphaeraceae relating to found Hangzhou. LDA effect size showed arbuscular mycorrhizal fungi (AMF) Longjing43. Field experiments further confirmed colonization rate AMF Zhongcha108. This finding testified be major potentially enhanced resistance. Overall, our results affected greater varieties, might more sensitive change microenvironments. Furthermore, we several microorganisms, which great significance improving environment plants. These may also help reveal mechanism useful for mitigating climate change-associated challenges future.

An alginate-based encapsulation enhances shelf life and bioactivity of the entomopathogenic fungus, Metarhizium anisopliae

Egyptian Journal of Biological Pest Control, Journal Year: 2023, Volume and Issue: 33(1)

Published: July 10, 2023

Abstract Background This study evaluated the shelf life and effectiveness of Metarhizium anisopliae encapsulated in Na (sodium)-alginate matrix. Air-flow-dried freeze-dried beads containing conidia M. produced submersion liquid broth were fabricated characterized. Shelf efficacy against three species white grubs, namely Holotrichia serrata , Adoretus sp., Lepidiota mansueta, under greenhouse conditions. Results The mean size wet ranged between 1.4 3.2 mm. that dried through freeze drying 0.55 2.3 However, air flow 2.35 Viability was more stored at 8 °C compared to air-flow-dried with 20.0 × 10 7 16.00 CFU/g, respectively, after two weeks drying. Further, supported conidial viability till months 2.0 CFU/g. LC 50 values 21 days treatment 0.35 (2.1 CFU/g), 0.31 0.76 mg CFU/g) H. serrata, L. respectively.
