On the phylogeny of members of Ceratocystis s.s. and Ophiostoma that possess different anamorphic states, with emphasis on the anamorph genus Leptographium, based on partial ribosomal DNA sequences
(2000-07-31)
Phylogenetic analysis of partial ribosomal DNA sequences was undertaken to assess the phylogenetic distribution of ophiostomatoid anamorphs with an emphasis on members of Leptographium and the generic limits of Ceratocystis ...
Phylogenetic analysis of the small subunit ribosomal RNA gene of the hyphochytrid Rhizidiomyces apophysatus
(2000-01-31)
The potential relationship of the uniflagellate hyphochytrids with biflagellate stramenopiles is still not clearly resolved. Thus, we have expanded the number of isolates and taxa of hyphochytrids compared. The phylogenetic ...
Unusual compact rDNA gene arrangements within some members of the Ascomycota: evidence for molecular co-evolution between ITS1 and ITS2
(2005-08-06)
The internal transcribed spacers of the ribosomal DNA tandem repeat were examined in members of the ascomycetous genus Sphaeronaemella. Species of Sphaeronaemella and its mitotic counterpart Gabarnaudia, have a compact ...
Three new species of Ophiostoma and notes on Cornuvesica falcata
(2003-01-31)
Sampling of beetles, beetle galleries, and stained tree tissues by ourselves and others to obtain isolates of ophiostomatoid fungal species yielded three Ceratocystiopsis-like entities. Using partial rDNA sequences, these ...
Notes on Ceratocystis brunnea and some other Ophiostoma species based on partial ribosomal DNA sequence analysis
(2003-08-30)
Ribosomal gene sequence data were obtained from a nonfruiting culture originally identified as Ceratocystis brunnea R.W. Davidson; this species was considered a nomen dubium by Upadhyay (1981) due to a presumptive lack of ...
The nuclear small subunit ribosomal genes of Sphaeronaemella helvellae, Sphaeronaemella fimicola, Gabarnaudia betae, and Cornuvesica falcata: phylogenetic implications
(2004-06-16)
Sequences were obtained from the nuclear small subunit ribosomal RNA genes for representatives of four ophiostomatoid genera (Ceratocystis, Gondwanamyces, Cornuvesica, and Sphaeronaemella) to resolve their phylogenetic ...
Analysis of restriction fragment length polymorphisms in the ribosomal DNA of a selection of anaerobic chytrids
(2000-07-31)
Anaerobic chytrid strains (representing four genera and seven species based on morphological characters), obtained from a variety of hosts, were analysed for variability within the 5' terminal segment of the ribosomal large ...
