Soil streptomycetes are commonly antagonistic against plant pathogens. However, interactions involving increased defense responses in the host plant, leading to suppression of plant disease development, have not yet been detailed. Here, the mechanisms were studied of disease suppression by Streptomyces sp. GB 4-2 against Heterobasidion root and butt rot in Norway spruce (Picea abies) seedlings. GB 4-2 promoted mycelial growth of the phytopathogenic fungus, germination rate of fungal spores… Expand
Biocontrol of Root Diseases and Growth Promotion of the Tuberous Plant Aconitum carmichaelii Induced by Actinomycetes Are Related to Shifts in the Rhizosphere Microbiota
TLDR
A preparation of two Actinomycetes plays a role in the biocontrol of root diseases and growth promotion of A. carmichaelii by inhibiting pathogen growth and shaping the rhizosphere microbiota. Expand
Antagonistic Streptomyces enhances defense-related responses in cotton for biocontrol of wilt caused by phytotoxin of Verticillium dahliae
TLDR
The results indicate that the induction of systemic disease resistance and the reduction of VD-toxin’s pathogenic effect are two important mechanisms of antagonistic Streptomyces BCA for biocontrol of Verticillium wilt of cotton. Expand
Biological Control of Lettuce Drop and Host Plant Colonization by Rhizospheric and Endophytic Streptomycetes
TLDR
S. exfoliatus FT05W has high potential to be exploited in agriculture for managing soil borne diseases barely controlled by available plant protection products and demonstrated Streptomyces' capability to interact with the host from early stages of seed germination and root development. Expand
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-induced resistance against oak powdery mildew involves host plant responses in defense, photosynthesis, and secondary metabolism pathways.
Rhizobacteria are known to induce defense responses in plants without causing disease symptoms, resulting in increased resistance to plant pathogens. This study investigated how Streptomyces sp.Expand
Rhizospheric streptomycetes as potential biocontrol agents of Fusarium and Armillaria pine rot and as PGPR for Pinus taeda
TLDR
It was found that all five isolates were able to inhibit the rhizomorph production, with the best performance of the isolate A43, which was capable of inhibiting both fungi, Fusarium and Armillaria. Expand
Selection of Streptomyces against soil borne fungal pathogens by a standardized dual culture assay and evaluation of their effects on seed germination and plant growth
TLDR
The adapted dual culture assay allowed us to compare the inhibition of individual Streptomyces strains against six fungal soil borne pathogens and found the best selected strains were able to colonize the four vegetable crops and have a potential to be developed into biocontrol products. Expand
Induction of Systemic Resistance in Crop Plants Against Plant Pathogens by Plant Growth-Promoting Actinomycetes
TLDR
Traits involved in plant growth-promoting actinomycetes (PGPA)-mediated induced systemic resistance (ISR) will be discussed. Expand

Suppression of plant defence response by a mycorrhiza helper bacterium.
TLDR
AcH 505 promotes plant root colonization by Heterobasidion strains that are tolerant to antifungal metabolites produced by the bacterium, which may result from unknown bacterial factors that suppress the plant defence response. 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
It is hypothesized that root and nodule colonization is one of several mechanisms by which Streptomyces acts as a naturally occurring plant growth-promoting bacterium in pea and possibly other leguminous plants. Expand
Defence related reactions of seedling roots of Norway spruce to infection by Heterobasidion annosum (Fr.) Bref.
TLDR
Norway spruce seedlings were cultivated in sterile conditions and Roots were infected with a concentration series of germinating conidiospores of Heterobasidion annosu m, causing a greater hypersensitive response than protein fractions but less than NaCl, Polygalacturonic acid or ethephon. Expand
Induced resistance to pathogenic fungi in norway spruce
TLDR
Protection was demonstrated to be pathogen nonspecific, as trees that had been pretreated with a medium dosage of the root rot fungus Heterobasidion annosum showed enhanced resistance to challenge inoculation with C. polonica. Expand
The establishment of vesicular-arbuscular mycorrhiza under aseptic conditions.

  • 1962
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
Effects of Rhizoctonia infection and drought on peroxidase and chitinase activity in Norway spruce (Picea abies).
TLDR
Results suggest that at an early stage of infection and drought stress, the two stresses can be distinguished by the temporal appearance and isoform profile of peroxidases and chitinases. Expand
