Characterization of North American Armillaria species by nuclear DNA content and RFLP analysis
Twenty-six isolates representing nine North American Armillaria species were investigated with flow cytometry and RFLP (restriction fragment length polymorphism) analyses to determine their nuclear DNA content and RFLP profile. Three putatively diploid isolates of A. ostoyae, A. gemina, A. calvescens, A. sinapina, A. mellea, A. gallica, A. nabsnona, and North American Biological Species (NABS) ...
متن کاملCharacterization of North American Armillaria species: genetic relationships determined by ribosomal DNA sequences and AFLP markers
Phylogenetic and genetic relationships among 10 North American Armillaria species were analysed using sequence data from ribosomal DNA (rDNA), including intergenic spacer (IGS-1), internal transcribed spacers with associated 5.8S (ITS + 5.8S), and nuclear large subunit rDNA (nLSU), and amplified fragment length polymorphism (AFLP) markers. Based on rDNA sequence data, the nLSU region is less va...
متن کاملMolecular Identification of Armillaria gallica from the Niobrara Valley Preserve in Nebraska
Armillaria isolates were collected from a unique forest ecosystem in the Niobrara Valley Preserve in Nebraska, USA, which comprises a glacial and early postglacial refugium in the central plains of North America. The isolates were collected from diverse forest trees representing a unique mixture of forest types. Combined methods of rDNA sequencing and flow cytometric measurements of nuclear DNA...
متن کاملCharacterization of Armillaria isolates from tea (Camellia sinensis) in Kenya.
Armillaria is a primary root rot pathogen of tea (Camellia sinensis) in Kenya. The main species presently described in this country are A. mellea and A. heimii. A survey covering fourteen districts of Kenya was carried out and forty-seven isolates of Armillaria collected. Cultural morphology, rhizomorph characteristics, somatic incompatibility and features of basidiomata were used to characteri...
متن کاملArmillaria altimontana, a new species from the western interior of North America.
Armillaria altimontana, previously considered North American biological species (NABS) X, is described as new. To date, it appears that A. altimontana prefers higher-elevation, mesic sites within the dry, conifer forest zone of western interior North America. This species has been found on hardwoods and conifers and is associated most commonly with Abies-dominated forest types in southern Briti...
