Why Mushrooms Have Evolved to Be So Promiscuous: Insights from Evolutionary and Ecological Patterns

Pheromone receptor Consistent with a role of mating type in mediating cytoplasmic-nuclear genomic conflict, Agaricomycetes have evolved away from a haploid yeast phase towards hyphal fusions that display reciprocal nuclear migration after mating rather than cytoplasmic fusion. Importantly, the evolution of this mating behavior is precisely timed with the onset of diversification of mating type alleles at the pheromone/receptor mating type loci that are known to control reciprocal nuclear migration during mating. -

Abstract Downloaded from Incompatibility systems in which individuals bearing identical alleles reject each other favor the maintenance of a diversity of alleles. Mushroom mating type loci (MAT) encode for dozens or hundreds of incompatibility alleles whose loss from the population is greatly restricted through negative frequency selection, leading to a system of alleles with highly divergent sequences. Here, we use DNA sequences of homeodomain (HD) encoding genes at the locus of five MAT http://mbe.oxfordjournals.org/ closely related species of the root rot basidiomycete Heterobasidion annosum sensu lato to show that the extended coalescence time of MAT alleles greatly predates speciation in the group, contrasting loci outside of MAT that show allele divergences largely consistent with the species phylogeny with those of MAT, which show rampant trans-species poly- morphism. -

Infection and growth of Heterobasidion spp. in Picea abies – Control by Phlebiopsis gigantea stump treatment. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7035-8. In economical terms, species of Heterobasidion are among the most severe fungal pests in coniferous forests of the northern hemisphere. The fungi cause interior decay in the stem of trees and trees may also die as a cause of infection. Two species of Heterobasidion have been identified in Sweden, Heterobasidion annosum s.s. (Fr.) Bref. and Heterobasidion parviporum Niemelä & Korhonen. The former has been identified from southern to central Sweden whereas the latter is present throughout the whole country. Stump treatment, using chemical or biological treatment agents, is the most widely used silvicultural method to prevent infection by Heterobasidion. This thesis mainly focuses on different aspects of biological stump treatment using Phlebiopsis gigantea (Fr.) Jül. The effectiveness of stump treatment against air-borne Heterobasidion spores with P. gigantea, when applied at different rates of stump coverage was investigated in southern Sweden. The results showed that, in order to achieve the best control, the aim should be to cover the complete stump surface with the treatment agent. In another field experiment in southern Sweden the effectiveness of Finish and Swedish strains of P. -

Heterobasidion Root Rot
Heterobasidion root rot Genetic mapping of virulence and evolutionary history Kerstin Dalman Faculty of Natural Resources and Agricultural Sciences Department of Forest Mycology and Pathology Uppsala Doctoral Thesis Swedish University of Agricultural Sciences Uppsala 2010 Acta Universitatis Agriculturae Sueciae 2010:81 ISSN 1652-6880 ISBN 978-91-576-7526-2 © 2010 Kerstin Dalman, Uppsala Print: SLU Service/Repro, Uppsala 2010 2 Heterobasidion root rot. Genetic mapping of virulence and evolutionary history Abstract Heterobasidion annosum (Fr.) Bref. sensu lato (s.l.) is a necrotrophic pathogen causing damage to conifers in the Northern Hemisphere. H. annosum s.l. consists of five species: three European [H. annosum sensu stricto (s.s.), H. parviporum and H. abietinum] and two North American (H. irregulare and H. occidentale); all with different but partially overlapping host preferences. A multilocus phylogenetic tree was built and the divergence times were estimated. Plate tectonics is likely to have been the main factor influencing Heterobasidion speciation and biogeography. Along with the geographical separation, the Heterobasidion species have specialized on different host genera. The H. annosum species complex originated in Laurasia and the H. annosum s.s./H. irregulare and H. parviporum/H. abietinum/H. occidentale ancestral species emerged between 45 million–60 million years ago in the Palaearctic. The data imply that H. irregulare and H. occidentale colonized North America via different routes: H. irregulare colonizing from the east via Trans Atlantic land bridges and H. occidentale colonizing from the west via the Bering Land Bridge. Alternatively H. occidentale originated from North America. Identification of virulence factors is important for understanding the Heterobasidion–conifer pathosystem. -
