Genomic insights into the carbohydrate catabolism of Cairneyella variabilis gen. nov. sp. nov., the first reports from a genome of an ericoid mycorrhizal fungus from the southern hemisphere.

This paper describes a novel species of ericoid mycorrhizal fungus from Australia, Cairneyella variabilis, Midgley and Tran-Dinh, gen. nov. sp.

Genetic population structure of the ectomycorrhizal fungus Pisolithus microcarpus suggests high gene flow in south-eastern Australia.

Pisolithus are ectomycorrhizal fungi that associate with roots of numerous plant species in natural and plantation forests worldwide. Despite the fact that Pisolithus spp. are present in plantation forests in many countries, knowledge of the genetic population structure of Pisolithus spp.

Ectomycorrhizal mycobionts of Pisonia grandis on coral cays in the Capricorn-Bunker group, Great Barrier Reef, Australia.

The diversity of ectomycorrhizal mycobionts of Pisonia grandis (Nyctaginaceae) from coral cays in the Capricorn-Bunker group, Great Barrier Reef, Australia, was examined. Only two ectomycorrhiza morphotypes (brown and black) were identified in soil from seven cays and DNA from both morphotypes was subjected to ITS-RFLP and sequence analysis. The brown morphotype was present in soil from all cays but the black morphotype was only observed in soil from three cays.

Development of markers for simple sequence repeat-rich regions that discriminate between Pisolithus albus and P. microcarpus.

Inter-simple sequence repeat PCR (ISSR-PCR) was used to develop markers for simple sequence repeat-rich (SSR) regions for investigation of genetic relatedness of Pisolithus isolates collected from eastern mainland Australia. Primers were designed to amplify ten SSR-rich regions and these were used to screen 14 Pisolithus isolates. Two amplified loci showed size polymorphisms among the isolates (regarded as polymorphic), two were monomorphic for all isolates, while the remainder amplified alleles for only some isolates.
