Horizontally Transmitted Symbionts and Host Colonization of Ecological Niches
Facultative or "secondary" symbionts are common in eukaryotes, particularly insects. While not essential for host survival, they often provide significant fitness benefits. It has been hypothesized that secondary symbionts form a "horizontal gene pool" shuttling adaptive genes among host lineages in an analogous manner to plasmids and other mobile genetic elements in bacteria. However, we do no...
متن کاملExtensive proliferation of transposable elements in heritable bacterial symbionts.
We found that insertion sequence (IS) elements are unusually abundant in the relatively recently evolved bacterial endosymbionts of maize weevils. Because multicopy elements can facilitate genomic recombination and deletion, this IS expansion may represent an early stage in the genomic reduction that is common in most ancient endosymbionts.
متن کاملOrder of arrival structures arbuscular mycorrhizal colonization of plants.
Priority effects - the impact of a species' arrival on subsequent community development - have been shown to influence species composition in many organisms. Whether priority effects among arbuscular mycorrhizal fungi (AMF) structure fungal root communities is not well understood. Here, we investigated whether priority effects influence the success of two closely related AMF species (Rhizophagu...
متن کاملMitigation of chilling and freezing stresses through colonization with arbuscular mycorrhizal fungi in spring barley
Cold stress is an important limiting factor for cereal production. Barley is a host species for arbuscular mycorrhizal fungi (AMF) with a high genetic diversity in response to cold stress. In order to explore the mechanisms for the ameliorative effect of AMF under cold stress, an experiment was undertaken using completely randomized block design with three factors including temperature treatme...
متن کاملArbuscular mycorrhizal fungal colonization. Factors involved in host recognition.
The arbuscular mycorrhizal (AM) symbiosis is the association between fungi of the order Glomales (Zygomycetes) and the roots of terrestrial plants (Harley and Smith, 1983). Conservative estimates suggest that this ancient symbiosis, dating back to the early Devonian age (398 million years ago), affects approximately 90% of the Earth’s land plant species (Remy et al., 1994). This symbiosis is in...
