Bacillus vallismortis acts against ginseng root rot by modifying the composition and microecological functions of ginseng root endophytes

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Published: April 7, 2025

The endophytic microbiome serves a crucial function as secondary line of defense against pathogen invasion in plants. This study aimed to clarify the mechanism action ginseng plant growth-promoting rhizobacteria (PGPR) Bacillus vallismortis SZ-4 synergizing with microorganisms prevention and control root rot. Ginseng samples from susceptible group (CK) disease level 0-2 biocontrol (BIO) treated strain were collected. We employed high-throughput sequencing examine microbial community structure roots at different levels, explore beneficial bacteria, evaluate efficacy mitigating rot through synergistic interactions flora. application PGPR B. fungicide has been found help resist Fusarium solani by modulating richness populations. bacteria HY-43 HY-46 isolated identified velezensis based on morphological, physiological, biochemical characteristics, well 16S rDNA gyrB analyses. combined generate bacterial consortia CS4-43 CS4-46, respectively. Both CS4-46 significantly enhanced inhibitory effects single SZ-4, HY-46, rot, while also promoting growth. These findings offers theoretical foundation for studying microecological diseases new insights conducting research efficient precise management diseases.

Harnessing Beneficial Microbes for Drought Tolerance: A Review of Ecological and Agricultural Innovations

Agriculture, Journal Year: 2024, Volume and Issue: 14(12), P. 2228 - 2228

Published: Dec. 5, 2024

Drought is an increasingly critical global challenge, significantly impacting agricultural productivity, food security, and ecosystem stability. As climate change intensifies the frequency severity of drought events, innovative strategies are essential to enhance plant resilience sustain systems. This review explores vital role beneficial microbes in conferring tolerance, focusing on Plant Growth-Promoting Rhizobacteria (PGPR), mycorrhizal fungi, endophytes, actinomycetes, cyanobacteria. These microorganisms mitigate stress through diverse mechanisms, including osmotic adjustment, enhancement root architecture, modulation phytohormones, induction antioxidant defenses, regulation stress-responsive gene expression. Ecological innovations leveraging these have demonstrated significant potential bolstering resilience. Strategies such as soil microbiome engineering, bioaugmentation, integration microbial synergies within pest management frameworks sustainability. Additionally, advancements practices, seed coating, amendments, development consortia, precision agriculture technologies, validated effectiveness scalability interventions farming Despite promising advancements, several challenges hinder widespread adoption solutions. Environmental variability can affect performance, necessitating robust adaptable strains. Scale-up commercialization hurdles, economic constraints, regulatory safety considerations also pose barriers. Furthermore, complex interactions between microbes, plants, their environments require a deeper understanding optimize benefits consistently. Future research should focus integrating cutting-edge technologies genomics, synthetic biology, refine interventions. Collaborative efforts among academia, industry, government bridge gap practical implementation. By addressing harnessing innovations, it possible develop resilient sustainable systems capable thriving water-scarce world.

Fungal plant pathogen Colletotrichum shisoi identified as a potential biological control agent of invasive Perilla frutescens in the United States

Biocontrol Science and Technology, Journal Year: 2024, Volume and Issue: 34(4), P. 375 - 388

Published: April 2, 2024

Perilla frutescens (L.) Britton, an annual plant in the mint family, is considered invasive United States where it excludes native vegetation natural areas and can cause respiratory illness livestock. An effective biological control agent would improve perilla management, but none have been developed or proposed. This study investigated biocontrol potential of a fungal pathogen, Colletotrichum shisoi, recently found infecting North America. The growth rates morphology seven shisoi isolates were recorded. A virulence assay was performed on two accessions, number size foliar lesions produced used to select single isolate, isolate 21-072, exhibiting consistently high for further evaluation efficacy host specificity. Treatment with 0.5 mL 1 × 107 spores/mL H2O caused 52% reduction shoot height 84% root length seedlings compared treatment (P < 0.001). Seedlings treated 108 had 100% mortality rate. Formulation inoculum 1:1 water:oil emulsion reduced dew period requirements causing >50% from 48 24 h, oil emulsions exhibited mild phytotoxic effect seedlings. Four additional accessions susceptible C. 34 other species included range experiments disease symptoms following inoculation. These results suggest 21-072 could be antagonist likely poses low risk non-target impacts.

Development and application of the fungal plant pathogen Colletotrichum shisoi to control invasive Perilla frutescens

Biological Control, Journal Year: 2024, Volume and Issue: 194, P. 105543 - 105543

Published: May 31, 2024

Inadvertently introduced plant pathogens that infect invasive species might be effective weed biological control agents if developed for redistribution or augmentation of naturally occurring populations. Colletotrichum shisoi is likely an inadvertent introduction to the United States where it causes disease on perilla mint (Perilla frutescens). This study reports development and application C. as a agent. The effects dew period infection probability inoculum concentration biomass production were determined identify threshold dose required activity. Under controlled conditions, pathogen reduced biomass, flower production, interspecific competitive ability. In replicated field trial, both populations caused high mortality moderate changes in community composition over one growing season. Additionally, series experiments performed evaluate methods preservation spores. Overall, was found antagonist when applied inundatively under appropriate conditions. It may possible produce mass across invaded range North America, but further research needed adequate during transport application.
