Ambrosia fungi in the insect-fungi symbiosis in relation to cork oak decline
Revista Iberoamericana De Micologia, 2006Ambrosia fungi live associated with beetles (Scolytidae and Platypodidae) in host trees and act as a food source for the insects. The symbiotic relation is important to the colonizing strategies of host trees by beetles. Ambrosia fungi are dimorphic: they grow as ambrosial form and as mycelium.

Adaptive traits of bark and ambrosia beetle-associated fungi
Fungal Ecology, 2019 Abstract A phenotype is the expression of interactions between species genotype and environment. We quantified the contributions of ecological and phylogenetic associations to phenotypic variation in Geosmithia fungi. Geosmithia are symbiotic beetle-associated saprotrophs with a range of life histories and host specificities, including obligate ...

Ambrosia beetles and their associated fungi: research trends and techniques
Proceedings / Indian Academy of Sciences, 1985General characteristics of ambrosia fungus-beetle mutualism are described and recent trends for innovative research briefly indicated. Techniques to locate, collect, transport, maintain, isolate, and study fungi and beetles in the field and in vitro are reviewed in detail.

Phylogeny of asexual fungi associated with bark and ambrosia beetles
Mycologia, 2001Asexual ascomycetes were isolated from Polygraphus polygraphus or Hylurgops palliatus (Co- leoptera: Scolytidae) (NISK-93-208/44 and NISK-94- 166/39, respectively) in a Norway spruce (Picea abies) forest. Although the two fungal isolates are distinct in appearance and display specificity to different hosts, the isolates are genetically identical in the

Convergent origins of ambrosia fungi
Mycologia, 1996The genus Ambrosiella appears to be non- monophyletic based on evidence from cladistic anal- ysis of characters derived from nuclear encoded small subunit (18S) rDNA sequences. The conclusion also is supported by differential sensitivity to cyclohexi- mide. Six species of Ambrosiella (A. brunnea, A. sul- cati, A. gnathotrichi, A.

Multigene phylogeny of filamentous ambrosia fungi associated with ambrosia and bark beetles
Mycological Research, 2009Most 'ambrosia' fungi are members of a heterogeneous group of ophiostomatoids that includes the anamorph genera Ambrosiella, Raffaelea and Dryadomyces. The taxonomy of these fungi based on morphological features has been complicated by these features being poorly descriptive and having evolved convergently.

Virulence of Fungi Isolated from Ambrosia Beetles to Acer amoenum Branches
Plant Disease, 2021In Japan, no association between the ambrosia beetle and their fungal symbionts causing branch dieback or tree mortality on maple, Acer amoenum, has been reported. However, we identified dieback of several branches and numerous holes created by three species of ambrosia beetles, Euwallacea fornicatus, Euwallacea interjectus, and Platypus calamus, on ...

Pleomorphism in Some Ambrosia and Related Fungi
Transactions of the Kansas Academy of Science (1903-), 1963The term pleomorphism has been used to denote many conditions and variations encountered in dermatophytes or other fungi imperfecti. In one sense it implies the condition of cultural instability in comparatively old cultures, manifested by patches of fluffy aerial mycelium producing fewer conidia, as for example, in Trichophyton mentagrophytes (Robin ...

Multiple evolutionary origins lead to diversity in the metabolic profiles of ambrosia fungi
Fungal Ecology, 2019Abstract Ambrosia fungi are an ecological assemblage cultivated by ambrosia beetles as required nutrient sources. This mutualism evolved in multiple beetle and fungus lineages. Whether convergence in ecology led to convergent metabolism in ambrosia fungi is unknown.

Ambrosia Fungi: Extent of Specificity to Ambrosia Beetles
Science, 1966Experiments with developing ambrosia beetles and fungi indicate that beetles may feed on more than one species growing in their tunnels. The yeast-like ambrosia propagules in mycangia of beetles arise from conida and ascospores picked up by callow adults during their stay in tunnels.
