New myxosporeans parasitizing Phractocephalus hemioliopterus from Brazil: morphology, ultrastructure and SSU-rDNA sequencing

Diseases of Aquatic Organisms, 2018
Myxozoans are a diverse group of parasitic cnidarians, with some species recognized as serious pathogens to their hosts. The present study describes 2 new myxobolid species (Myxobolus figueirae sp. nov. and Henneguya santarenensis sp. nov.) infecting skin and gill filaments of the Amazonian pimelodid fish Phractocephalus hemioliopterus, based on ...

Molecular Phylogeny of Conjugating Green Algae (Zygnemophyceae, Streptophyta) Inferred from SSU rDNA Sequence Comparisons

Journal of Molecular Evolution, 2003
Nuclear-encoded SSU rDNA sequences have been obtained from 64 strains of conjugating green algae (Zygnemophyceae, Streptophyta, Viridiplantae). Molecular phylogenetic analyses of 90 SSU rDNA sequences of Viridiplantae (inciuding 78 from the Zygnemophyceae) were performed using complex evolutionary models and maximum likelihood, distance, and maximum ...

Assessment of prokaryote to eukaryote ratios in environmental samples by SSU rDNA length polymorphism

Antonie van Leeuwenhoek, 2019
Microbial communities are important regulators of many processes in all ecosystems. Understanding of ecosystem processes requires at least an overview of the involved microorganisms. While in-depth identification of microbial species in environmental samples can be achieved by next generation sequencing, profiling of whole microbial communities can be ...

An exceptional group-I intron-like insertion in the SSU rDNA of lichen mycobionts

Current Genetics, 1999
An exceptional group-I intron-like insertion at position 940 of the nuclear small subunit rDNA is found in lichen mycobionts of the families Parmeliaceae and Lecanoraceae. This shared insertion site is exceptional as it follows a G. Although several features of the self-splicing Tetrahymena intron are missing, the conserved structure of the presumed ...

Major lineages of Dothideomycetes (Ascomycota) inferred from SSU and LSU rDNA sequences

Mycological Research, 2001
The phylogeny of the Dothideomycetes was investigated using nucleotide sequences of SSU and LSU rDNA. 32 new sequences of these regions from 18 species were aligned with five sequences obtained from GenBank, including two representatives of Pezizomycetes used as outgroup.

Phylogenetic analysis of Antrodia and related taxa based on partial mitochondrial SSU rDNA sequences

Antonie van Leeuwenhoek, 2003
Sequences of mitochondrial SSU rDNA were obtained from six species of Antrodia and related fungal taxa to reveal their phylogenetic relationships. Phylogenetic analysis showed that the species of Antrodia did not cluster into a single clade. Brown rot fungi were separated into two main groups through which Antrodia was dispersed.

PHYLOGENY OF THE EUGLENOPHYTES INFERRED FROM SSU AND LSU rDNA

Journal of Phycology, 2001
Zimmermann, S. & Triemer, R. E.Department of Life Sciences, Rutgers University, Piscataway, NJ 08854 USAThe phylogeny of the Euglenophytes has previously been examined using the SSU rDNA. Results from these analyses indicated that the phototrophic genera are not monophyletic. To test this hypothesis, a second gene was sequenced, the LSU rDNA.

SSU rDNA Characterization of Lymnaeid Snails Transmitting Human Fascioliasis in South and Central America

The Journal of Parasitology, 1997
The small subunit (18S) rRNA gene sequences of the lymnaeid morphs I and II (Mollusca: Gastropoda: Basommatophora: Lymnaeidae) transmitting human fascioliasis in the high endemic zone of the northern Bolivian Altiplano and of Lymnaea cubensis from Mexico and Guadeloupe island (Caribbean) have been obtained by direct polymerase chain reaction PCR cycle ...

Variable sizes of introns in the SSU rDNA in three species of Roccella (Arthoniales, Euascomycetes)

Current Genetics, 1999
Three species of the lichenized fungus Roccella (Arthoniales, Euascomycetes), R. canariensis, R. tuberculata and R. montagnei, were found to possess insertions in the first half of the nuclear SSU rDNA. Both the number and the type of these insertions varied between and within species. At position 516 the insertions belonged to group-IC1 introns with a

Phylogenetic position of the enigmatic myxomycete genus Kelleromyxa revealed by SSU rDNA sequences

Mycological Progress, 2013
The coprophilous myxomycete Kelleromyxa fimicola (Dearn. & Bisby) Eliasson was first described in 1929 as Licea fimicola Dearn. & Bisby. Based on the superficial resemblance of its sporocarps to those of Licea biforis, the species was placed within the Liceales, an order assigned by molecular phylogenies to the bright-spored clade of myxomycetes ...
