Polyphyletic origin of the genus Physarum (Physarales, Myxomycetes) revealed by nuclear rDNA mini-chromosome analysis and group I intron synapomorphy

Autor: Nandipati Satish CR, Haugli Kari, Coucheron Dag H, Haskins Edward F, Johansen Steinar D

Publikováno v: BMC Evolutionary Biology, Vol 12, Iss 1, p 166 (2012)

Abstract Background Physarales represents the largest taxonomic order among the plasmodial slime molds (myxomycetes). Physarales is of particular interest since the two best-studied myxomycete species, Physarum polycephalum and Didymium iridis, belon

Differential expression patterns of conserved miRNAs and isomiRs during Atlantic halibut development

Autor: Bizuayehu Teshome T, Lanes Carlos FC, Furmanek Tomasz, Karlsen Bård O, Fernandes Jorge MO, Johansen Steinar D, Babiak Igor

Publikováno v: BMC Genomics, Vol 13, Iss 1, p 11 (2012)

Abstract Background MicroRNAs (miRNAs) play a major role in animal ontogenesis. Size variants of miRNAs, isomiRs, are observed along with the main miRNA types, but their origin and possible biological role are uncovered yet. Developmental profiles of

Halibut mitochondrial genomes contain extensive heteroplasmic tandem repeat arrays involved in DNA recombination

Autor: Moum Truls, Jørgensen Tor E, Karlsen Bård O, Mjelle Kenneth A, Johansen Steinar D

Publikováno v: BMC Genomics, Vol 9, Iss 1, p 10 (2008)

Abstract Background Halibuts are commercially important flatfish species confined to the North Pacific and North Atlantic Oceans. We have determined the complete mitochondrial genome sequences of four specimens each of Atlantic halibut (Hippoglossus

A mitogenomic approach to the taxonomy of pollocks: Theragra chalcogramma and T. finnmarchica represent one single species

Autor: Coucheron Dag H, Fevolden Svein-Erik, Christiansen Jørgen, Breines Ragna, Ursvik Anita, Johansen Steinar D

Publikováno v: BMC Evolutionary Biology, Vol 7, Iss 1, p 86 (2007)

Abstract Background The walleye pollock (Theragra chalcogramma) and Norwegian pollock (T. finnmarchica) are confined to the North Pacific and North Atlantic Oceans, respectively, and considered as distinct species within the family Gadidae. We have d

Short-term sequence evolution and vertical inheritance of the Naegleria twin-ribozyme group I intron

Autor: De Jonckheere Johan F, Einvik Christer, Wikmark Odd-Gunnar, Johansen Steinar D

Publikováno v: BMC Evolutionary Biology, Vol 6, Iss 1, p 39 (2006)

Abstract Background Ribosomal DNA of several species of the free-living Naegleria amoeba harbors an optional group I intron within the nuclear small subunit ribosomal RNA gene. The intron (Nae.S516) has a complex organization of two ribozyme domains
