Plants have a variety of chemical and anatomical defences, whose strengths depend on biotic and environmental influences. We show here that root inoculation with belowground bacteria, filamentous gram-positive streptomycetes, can induce plant defence responses. Such induced plant responses can occur belowground in the roots, but also aboveground, in the leaves, and include priming (sensitizing) like characters. Streptomycetes have also evolved mechanisms to facilitate plant root symbioses… Expand
Synergists and antagonists in the rhizosphere modulate microbial communities and growth of Quercus robur L.
TLDR
The Streptomyces AcH505 strain promoted growth of oak microcuttings at bud swelling stage B during maximal root elongation and enhanced the abundance of saprophytic and ectomycorrhizal fungi in the rhizosphere by 158% with respect to controls. Expand
Ectomycorrhizal Helper Bacteria: The Third Partner in the Symbiosis
TLDR
This chapter will discuss perspectives on the beneficial use of ectomycorrhizal symbiosis with nitrogen-fixing bacteria to develop predictive models that could be used to improve the mycorrhization processes with the further aim of obtaining plants infected with Tuber magnatum Pico, the most economically important truffle species that remains difficult to cultivate.

Natural products in soil microbe interactions and evolution.
TLDR
This review examines interspecies interactions, and the natural products involved, as they have been presented in literature stemming from four disciplines: soil science, interspecies microbiology, ecology, and evolutionary biology, and considers how these interactions fit into accepted paradigms of signaling, cueing, and coercion.

Biocontrol of Cereal Crop Diseases Using Streptomycetes
TLDR
It is argued that a greater understanding of these mechanisms may enable the development of protective plant root microbiomes with a greater abundance of beneficial bacteria, such as Streptomyces species. Expand
Streptomyces competition and co-evolution in relation to plant disease suppression.
TLDR
It is argued that shifting the focus of research from short-term disease suppression to the population ecology and evolutionary biology of antagonistic Streptomyces in soil will enhance prospects for effective management. Expand
Chemical ecology of antibiotic production by actinomycetes.
TLDR
The environmental triggers and cues that control natural product formation by actinomycetes are reviewed and pointers as to how these insights may be harnessed for drug discovery are provided. Expand
Nocardiopsis species: Incidence, ecological roles and adaptations.
Members of the genus Nocardiopsis are ecologically versatile and biotechnologically important. They produce a variety of bioactive compounds such as antimicrobial agents, anticancer substances, tumorExpand
Assessment of the potential role of Streptomyces strains in the revegetation of semiarid sites: the relative incidence of strain origin and plantation site on plant performance and soil quality indicators
TLDR
Strain origin and the biological fertility of the plantation site should be considered in the selection of strains of actinobacteria for use in the revegetation with shrub species in semiarid environments. Expand
Screening for potential Striga hermonthica fungal and bacterial biocontrol agents from suppressive soils in Western Kenya
Striga hermonthica is a hemiparasitic weed that causes huge grain yield losses to small-scale farmers in Africa. Effective biocontrol agents against S. hermonthica can sustainably mitigate theseExpand
Evaluation of Streptomyces spp. against Fusarium oxysporum f. sp. ciceris for the management of chickpea wilt
TLDR
The results of this study showed that it may be possible to manage chickpea Fusarium wilt disease effectively by using Streptomyces species, as biocontrol agents. 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
Priming in plant-pathogen interactions.
TLDR
These studies show that priming often depends on the induced disease resistance key regulator NPR1 (also known as NIM1 or SAI1) and that primed has a major effect on the regulation of cellular plant defence responses. 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
Evolution of plant pathogenicity in Streptomyces.
TLDR
The recently available genome sequence of S. scabies will accelerate research on host-pathogen interactions and help identify the mechanisms used by plant pathogenic species to manipulate their hosts. Expand
Pseudomonas syringae manipulates systemic plant defenses against pathogens and herbivores.
TLDR
It is reported that virulent strains of the bacterial phytopathogen Pseudomonas syringae induce systemic susceptibility to secondary P. syringsae infection in the host plant Arabidopsis thaliana, and data suggest that SIS may be a consequence of the previously described mutually antagonistic interaction between the salicylic acid and JA signaling pathways. Expand
Endophytic actinobacteria induce defense pathways in Arabidopsis thaliana.
TLDR
The endophytic actinobacteria appear to be able to "prime" both the SAR and JA/ET pathways, upregulating genes in either pathway depending on the infecting pathogen. Expand
Biological Control of Phytophthora Root Rots on Alfalfa and Soybean with Streptomyces
TLDR
A collection of 53 antibiotic-producing Streptomyces isolated from soils from Minnesota, Nebraska, and Washington were evaluated for their ability to inhibit plant pathogenic Phytophthora medicaginis and Phytophile sojae in vitro, and eight isolates tested significantly reduced root rot severity in alfalfa and soybean.

The microbial basis of specific suppression to four diseases, Fusarium wilts, potato scab, apple replant disease, and take-all, is discussed and the microbial composition and complex interactions in suppressive soils are dissected. Expand
Plant defence signalling induced by biotic attacks.
TLDR
Recent research has shown how plants integrate these signals to coordinate defence by regulation of key metabolic pathways, although there is still much to be learnt. Expand
