Environmental Conditions Determine the Course and Outcome of Phytoplankton Chytridiomycosis
Rohrlack, Thomas; Haande, Sigrid; Molversmyr, Åge; Kyle, Marcia (Journal article, 2015)Chytrid fungi are highly potent parasites of phytoplankton. They are thought to force phytoplankton organisms into an evolutionary arms race with high population diversity as the outcome. The underlying selection regime ... -
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 ... -
Heteroxanthin as a pigment biomarker for Gonyostomum semen (Raphidophyceae)
Hagman, Camilla Hedlund Corneliussen; Rohrlack, Thomas; Uhlig, Silvio; Hostyeva, Vladyslava (Peer reviewed; Journal article, 2019)The ability to identify drivers responsible for algal community shifts is an important aspect of environmental issues. The lack of long-term datasets, covering periods prior to these shifts, is often limiting our understanding ... -
Historical Planktothrix diversity across seven Norwegian lakes implies environmentally driven niche differentiation
Kyle, Marcia; Andersen, Tom; Haande, Sigrid; Rohrlack, Thomas (Journal article, 2015) -
Spectrophotometric analysis of pigments: A critical assessment of a high-throughput method for analysis of algal pigment mixtures by spectral deconvolution
Thrane, Jan-Erik; Kyle, Marcia; Striebel, Maren; Haande, Sigrid; Grung, Merete; Rohrlack, Thomas; Andersen, Tom (Journal article, 2015) -
The red queen race between parasitic chytrids and their host, planktothrix: A test using a time series reconstructed from sediment DNA
Kyle, Marcia; Haande, Sigrid; Ostermaier, Veronika; Rohrlack, Thomas (Journal article, 2015) -
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 ...
