Early origin of foraminifera suggested by SSU rRNA gene sequences.
Foraminifera are one of the largest groups of unicellular eukaryotes with probably the best known fossil record. However, the origin of foraminifera and their phylogenetic relationships with other eukaryotes are not well established. In particular, two recent reports, based on ribosomal RNA gene sequences, have reached strikingly different conclusions about foraminifera's evolutionary position ...
متن کاملUncultivated Microbial Eukaryotic Diversity: A Method to Link ssu rRNA Gene Sequences with Morphology
Protists have traditionally been identified by cultivation and classified taxonomically based on their cellular morphologies and behavior. In the past decade, however, many novel protist taxa have been identified using cultivation independent ssu rRNA sequence surveys. New rRNA "phylotypes" from uncultivated eukaryotes have no connection to the wealth of prior morphological descriptions of prot...
متن کاملPhylogenetic analysis of the SSU rRNA gene from the piscine diplomonad Spironucleus torosus (Diplomonadida: Hexamitinae).
Previous studies have recorded Spironucleus torosus Poynton et Morrison, 1990 from several species of gadoid fishes, including the only freshwater gadoid, the burbot Lota lota (L.). Two morphologically different isolates of S. torosus have been described (elongate and pyriform). Both have been found in saltwater, while only the elongate has been found in freshwater. To address the conspecificit...
متن کاملMicrobial Diversity in Deep-sea Methane Seep Sediments Presented by SSU rRNA Gene Tag Sequencing
Microbial community structures in methane seep sediments in the Nankai Trough were analyzed by tag-sequencing analysis for the small subunit (SSU) rRNA gene using a newly developed primer set. The dominant members of Archaea were Deep-sea Hydrothermal Vent Euryarchaeotic Group 6 (DHVEG 6), Marine Group I (MGI) and Deep Sea Archaeal Group (DSAG), and those in Bacteria were Alpha-, Gamma-, Delta-...
متن کاملPhylogenetic position of Protoopalina intestinalis based on SSU rRNA gene sequence.
A robust recognition of phylogenetic affinities of Opalinidae-the peculiar multinucleated intestine commensals of frogs-is hindered by the absence of reliable molecular data. Up to now all attempts to sequence opalinid genes failed, as the obtained sequences labeled as Protoopalina intestinalis, Cepedea virguloidea, and Opalina ranarum in GenBank apparently originate from a zygomycete contamina...
