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.

Microbial diversity across tea varieties and ecological niches: correlating tea polyphenol contents with stress resistance

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

Published: Aug. 26, 2024

Introduction Microorganisms exhibit intricate interconnections with tea plants; however, despite the well-established role of microorganisms in crop growth and development, research on microbes within plant remains insufficient, particularly regarding endophytic microorganisms. Methods In this study, we collected samples leaves rhizosphere soils from ‘Zhuyeqi’, ‘Baojing Huangjincha#1’, ‘Baiye#1’, ‘Jinxuan’ varieties planted. Results Our analyses revealed significant variations polyphenol contents among varieties, ‘Zhuyeqi’ variety exhibiting higher levels polyphenols (>20% contents). Microbiome studies have that microbial community plants exhibited host specificity compared to rhizospheric community. Analyses across-ecological niches associated soil bacteria serve as a reservoir for plants, Bacillus may play crucial shaping bacterial niche levels. aforementioned analyses, degree leaf microorganisms, topological structure co-occurrence network is also more intricate, harboring greater number potential core its nodes. A closer examination was conducted further indicated harbored abundance biomarkers, bacteria, enriched Methylobacterium Sphingomonas distinct roles disease resistance drought resilience plants. Conclusion summary, study has shed light relationships their communities, unveiling importance polyphenols, offering valuable insights

Changes of physiological characteristics, element accumulation and hormone metabolism of tea leaves in response to soil pH

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Nov. 16, 2023

Soil acidification is very likely to affect the growth of tea trees and reduce yield. In this study, we analyzed effects soils with different pH on physiological characteristics leaves determined multi-element content hormone metabolomes by ICP-MS LC-MS/MS, based which further their interaction. The results showed that increasing soil (3.29~5.32) was beneficial increase available nutrient rhizosphere tree, improve antioxidant enzyme activity photosynthesis capacity tree leaves, promote tree. Orthogonal partial least squares discriminant analysis (OPLS-DA) bubble were used screen key elements hormones for effect redundancy (RDA) interaction network. an in favored accumulation seven (C, K, Ca, Mg, Mn, P, S) turn promoted synthesis six (salicylic acid, salicylic acid 2-O-β-glucoside, tryptamine, 2-oxindole-3-acetic indole-3-acetic trans-zeatin-O-glucoside).

Abstract Tea plantation ecosystems have a strong potential to sequester carbon (C) and reduce CO 2 emissions. However, the effects of different tea planting periods on soil organic (SOC) stocks mineralization related mechanisms are unclear. To address this knowledge gap, we investigated replacing evergreen broadleaf forests with plantations SOC rates by examining alterations in pools composition, microbial community functional genes C‐cycling enzyme activities. The content forest, 30‐, 50‐ 100‐year‐old were 1.91%, 2.37%, 2.87% 3.69%, respectively, 0–20 cm depth (100‐year‐old > 50‐year‐old 30‐year‐old forest). Cumulative –C emissions increased 38.1% (114 mg C kg −1 soil), 49.9% (157 100.2% (171 soil) compared forest (228 after had been grown for 30, 50 100 years, respectively; however, cumulative did not differ significantly between 30‐ plantations. rate was positively particulate (POC), water‐soluble (WSOC), biomass (MBC), O‐alkyl contents, as well β‐glucosidase/cellobiohydrolase activities GH48 / cbhI abundance; contrast, negatively correlated aromatic content.
