This Community Page describes a resource of 700 transcriptomes from marine microbial eukaryotes to help understand their role in the world's oceans.
The Atlantic salmon genome provides insights into rediploidization
- S. Lien, B. Koop, W. Davidson
- BiologyNature
- 18 April 2016
It is found that genes that were retained as duplicates after the teleost-specific whole-genome duplication 320 million years ago were not more likely to be retained after the Ss4R, and that the duplicate retention was not influenced to a great extent by the nature of the predicted protein interactions of the gene products.
Ancient hybridizations among the ancestral genomes of bread wheat
- T. Marcussen, S. Sandve, O. Olsen
- BiologyScience
- 18 July 2014
It is implied that the present-day bread wheat genome is a product of multiple rounds of hybrid speciation (homoploid and polyploid) and lay the foundation for a new framework for understanding the wheat genome as a multilevel phylogenetic mosaic.
Phylogenomics Reshuffles the Eukaryotic Supergroups
- Fabien Burki, K. Shalchian-Tabrizi, J. Pawłowski
- BiologyPLoS ONE
- 29 August 2007
This work reports the sequencing of expressed sequence tags for two species belonging to the supergroup Rhizaria and presents the analysis of a unique dataset combining 29908 amino acid positions and an extensive taxa sampling made of 49 mainly unicellular species representative of all supergroups.
Genetic divergence and phylogeographic relationships among European perch (Perca fluviatilis) populations reflect glacial refugia and postglacial colonization
- C. Nesbø, T. Fossheim, L. A. Vøllestad, K. Jakobsen
- Environmental Science, BiologyMolecular Ecology
- 1 September 1999
Investigation of postglacial colonization routes of freshwater fishes in Europe suggests that present perch populations in western and northern Europe were colonized from three main refugia, located in southeastern, northeastern and western Europe.
The genome sequence of Atlantic cod reveals a unique immune system
- B. Star, A. Nederbragt, K. Jakobsen
- BiologyNature
- 8 September 2011
The genome sequence of Atlantic cod is presented, showing evidence for complex thermal adaptations in its haemoglobin gene cluster and an unusual immune architecture compared to other sequenced vertebrates.
Natural Variation in the Microcystin Synthetase Operon mcyABC and Impact on Microcystin Production in Microcystis Strains
- B. Mikalsen, G. Boison, K. Jakobsen
- BiologyJournal of Bacteriology
- 1 May 2003
The results suggest that recombination between imperfect repeats, gene loss, and horizontal gene transfer can explain the distribution and variation within the mcyABC operon.
Discovery of Nuclear-Encoded Genes for the Neurotoxin Saxitoxin in Dinoflagellates
- Anke Stüken, Russell J. S. Orr, R. Kellmann, S. Murray, B. Neilan, K. Jakobsen
- Environmental Science, BiologyPLoS ONE
- 18 May 2011
It is shown that genes required for saxitoxin synthesis are encoded in the nuclear genomes of dinoflagellates, and sxtA, the unique starting gene of saxit toxin synthesis, is focused on, and it is demonstrated that the dinof lagellate transcripts of sXTA have the same domain structure as the cyanobacterial sxt a genes.
Multigene Phylogeny of Choanozoa and the Origin of Animals
- K. Shalchian-Tabrizi, M. Minge, T. Cavalier-smith
- BiologyPLoS ONE
- 7 May 2008
Phylogenetic trees using 78 proteins show that Ministeria is not sister to animals or choanoflagellates (themselves sisters to animals), but to Capsaspora, another protozoan with thread-like (filose) tentacles, while trees show ichthyosporean choanozoans as sisters to filozoa.
Evolution of Cyanobacteria by Exchange of Genetic Material among Phyletically Related Strains
- K. Rudi, O. Skulberg, K. Jakobsen
- BiologyJournal of Bacteriology
- 1 July 1998
It is suggested that exchange of genetic material for neutrally evolving genes may explain the apparent stability of cyanobacterial morphological characters, perhaps over billions of years.
