The aim of the present study was to determine whether the mycorrhiza helper bacterium Streptomyces sp. AcH 505 could serve as a biocontrol agent against Heterobasidion root and butt rot. Bacterial influence on mycelial growth of Heterobasidion sp. isolates, on the colonization of wood discs and Norway spruce (Picea abies) roots was determined. The effect of AcH 505 on plant photosynthesis, peroxidase activity and gene expression, and needle infections were investigated. AcH 505 was antagonistic… Expand
Root inoculation with a forest soil streptomycete leads to locally and systemically increased resistance against phytopathogens in Norway spruce.
TLDR
Host responses indicate that GB 4-2 induces both local and systemic defense responses in Norway spruce, and promotes mycelial growth of the phytopathogenic fungus but induced plant defense responses. Expand
Brevibacillus sp. promotes maize root colonization by Acaulospora tuberculata and the alteration of associated plant protein responses
TLDR
The alteration of some plant defense-related compounds and antioxidative enzyme activities that are associated with an enhancing maize root colonization by AM when co-inoculated with SUT47 are shown. Expand
Biotransformation of the Fungal Phytotoxin Fomannoxin by Soil Streptomycetes
TLDR
It is concluded that the streptomycete-mediated modulation of spruce infection with H. abietinum 331 does not depend on the availability of fomannoxin, and evidence is added to the observation that the lipophilic side chain of fmannoxin is an important structural element for its phytotoxicity.

Friends and foes: streptomycetes as modulators of plant disease and symbiosis
TLDR
It is argued towards the use of an integrated screening approach in the search for efficient biocontrol agents, including assays on in-vitro antagonism, plant growth, and disease suppression, to avoid strains that select for virulent pathogens or enhance disease development. Expand
Streptomyces AcH 505 triggers production of a salicylic acid analogue in the fungal pathogen Heterobasidion abietinum that enhances infection of Norway spruce seedlings
TLDR
Based on in vivo measurements of maximum photosystem II efficiency of Norway spruce seedlings, 5-FSA did not influence plant vitality, however, when challenged with H. abietinum 331, ergosterol amounts in infected roots increased significantly for 5- FSA pre-treated seedlings; the severity of the infection was comparable to that observed in the presence of Streptomyces AcH 505.

Newly identified helper bacteria stimulate ectomycorrhizal formation in Populus
TLDR
Novel MHB strains isolated from native Populus that improve L. bicolor root colonization on Populus are reported, which could be exploited for Populus species/genotypes nursery production as a means of improving establishment and survival in marginal lands. Expand
Infection with foliar pathogenic fungi does not alter the receptivity of Norway spruce seedlings to ectomycorrhizal fungi
TLDR
The results suggest that there are differences in resource allocation strategies between the fast- and slow-growing spruce families, which may indicate the presence of underlying host effects that regulate interactions with associated fungi. Expand

Abstract Soil microorganisms are key players in determining the plant growth and crop productivity worldwide. Among different microorganisms, members of the genus Streptomyces are one of the majorExpand
Impact of mycorrhiza helper bacterium Streptomyces sp. AcH 505 on the genetic and physiuological regulation in oaks associated to pathogenic and symbiotic fungi
TLDR
The study indicates that the presence of microorganisms and plant roots can both affect the nature of MHB-fungus interactions, and that mycorrhizal fungi may enhance MHB growth. Expand

Mycorrhiza helper bacterium Streptomyces AcH 505 induces differential gene expression in the ectomycorrhizal fungus Amanita muscaria.
TLDR
It is suggested that AcH 505 and AcH 1003 enhance mycorrhiza formation mainly as a result of promotion of fungal growth, leading to changes in fungal gene expression. Expand
Actinomycetales bacteria from a spruce stand: Characterization and effects on growth of root symbiotic and plant parasitic soil fungi in dual culture
TLDR
A group of bacterial strains were identified which significantly promoted growth of fly agaric hyphae and one of these strains was shown to additionally inhibit growth of pathogenic fungi such as Armillaria obscura and Heterobasidion annosum. Expand

TLDR
At first mycorrhizal infections were predominantly arbuscular, but many prominent vesicles developed as the seedlings declined, and then the fungus grew out of infected roots and colonized the agar, indicating that the fungus could not be subcultured without a living host. Expand
Auxofuran, a Novel Metabolite That Stimulates the Growth of Fly Agaric, Is Produced by the Mycorrhiza Helper Bacterium Streptomyces Strain AcH 505
TLDR
Characterization of these compounds provides the foundation for molecular analysis of the fungus-bacterium interaction in the ectomycorrhizal symbiosis between fly agaric and spruce. Expand
Impact on Arbuscular Mycorrhiza Formation ofPseudomonas Strains Used as Inoculants for Biocontrol of Soil-Borne Fungal Plant Pathogens
TLDR
The results of scanning electron and confocal microscopy demonstrated that strain F113 and its derivatives adhered to G. mosseae spores independent of the ability to produce DAPG, a concentration that might be present in the rhizosphere. Expand
Studies on the infection of Norway spruce roots by Heterobasidion annosum
TLDR
Results showed that attachment to root surface and penetration of root epidermal walls were facilitated using pregerminated conidiospores as inocula, and the induction of hypersensitive response was a function of both time and spore concentration. Expand

TLDR
Multiple microbial interactions involving bacteria and fungi in the rhizosphere are shown to provide enhanced biocontrol in many cases in comparison with biocOntrol agents used singly. Expand
