From Green to Red: Horizontal Gene Transfer of the Phycoerythrin Gene Cluster between Planktothrix Strains
Tooming-Klunderud, Ave; Sogge, Hanne; Rounge, Trine Ballestad; Nederbragt, Alexander Johan; Lagesen, Karin; Glöckner, Gernot; Hayes, Paul K; Rohrlack, Thomas; Jakobsen, Kjetill Sigurd (Journal article; Peer reviewed, 2013)Horizontal gene transfer is common in cyanobacteria, and transfer of large gene clusters may lead to acquisition of new functions and conceivably niche adaption. In the present study, we demonstrate that horizontal gene ... -
Gene Flow, Recombination, and Selection in Cyanobacteria: Population Structure of Geographically Related Planktothrix Freshwater Strains
Sogge, Hanne; Rohrlack, Thomas; Rounge, Trine Ballestad; Sønstebø, Jørn Henrik; Tooming-Klunderud, Ave; Kristensen, Tom; Jakobsen, Kjetill Sigurd (Journal article; Peer reviewed, 2013)Several Planktothrix strains, each producing a distinct oligopeptide profile, have been shown to coexist within Lake Steinsfjorden (Norway). Using nonribosomal peptide synthetase (NRPS) genes as markers, it has been shown ... -
Use of High Throughput Sequencing and Light Microscopy Show Contrasting Results in a Study of Phytoplankton Occurrence in a Freshwater Environment
Xiao, Xi; Sogge, Hanne; Lagesen, Karin; Tooming-Klunderud, Ave; Jakobsen, Kjetill Sigurd; Rohrlack, Thomas (Journal article; Peer reviewed, 2014)Assessing phytoplankton diversity is of primary importance for both basic and applied ecological studies. Following the advances in molecular methods, phytoplankton studies are switching from using classical microscopy to ...
