Determining species diversity of microfungal communities in forest tree roots by pure-culture isolation and DNA sequencing
Kwasna, Hanna; Bateman, Geoffrey L.; Ward, Elaine (2008-09)Pure-culture isolation from roots was compared with transformation of total DNA from roots followed by sequence analysis of ITS 1/2 rDNA of representative clones as methods for determining the abundance and composition of ... -
Lewia hordeicola sp. nov. from barley grain
Kwasna, Hanna; Ward, Elaine; Kosiak, Barbara (2006)Lewia hordeicola with Alternaria anamorph was isolated from barley grains in Norway. The fungus is homothallic. It produces fertile ascomata on synthetic nutrient agar (SNA) after long incubation at 4 C in the dark. On PCA ... -
Microbiota in Wheat Roots Evaluated by Cloning of ITS1/2 rDNA and Sequencing
Kwasna, Hanna; Bateman, Geoffrey L.; Ward, Elaine (2010-04)Fungi (17 species), oomycetous organisms (four species of Pythium) and a plasmodiophorid (Polymyxa graminis) were recorded in wheat roots analysed by cloning of the total ITS1/2 rDNA and sequencing of representative clones. ... -
Phylogenetic relationships among Zygomycetes from soil based on ITS1/2 rDNA sequences
Kwasna, Hanna; Ward, Elaine; Bateman, Geoffrey L. (2006-05)New information was obtained on the phylogeny of Zygomycetes. PCR-RFLP analysis showed ITS1/2 rDNA to provide appropriate markers for genetic studies on Zygomycetes at the population and species levels. The use of several ... -
Relationships among Fusarium spp estimated by comparing restriction fragment length polymorphisms in polymerase chain reaction-amplified nuclear rDNA
Bateman, Geoffrey L.; Kwasna, Hanna; Ward, Elaine (1996-12)Nuclear rDNA from 120 isolates of 34 Fusarium spp. and Microdochium nivale was compared by restriction fragment length polymorphism (RFLP) analysis after polymerase chain reaction amplification. The RFLPs allowed differentiation ... -
Relationships among Fusarium spp. estimated by comparing restriction fragment length polymorphisms in polymerase chain reaction amplified ribosomal DNA
Bateman, Geoffrey L.; Kwasna, Hanna; Ward, Elaine (1997)
