Amplicon-based and metagenomic approaches provide insights into toxigenic potential in understudied Atlantic Canadian lakes
Abstract
Cyanobacterial blooms and their toxigenic potential threaten freshwater resources worldwide. In Atlantic Canada, despite an increase of cyanobacterial blooms in the last decade, little is known about the toxigenic potential and the taxon...

Massive protein import into the early-evolutionary-stage photosynthetic organelle of the amoeba <i>Paulinella chromatophora</i>
Abstract
The endosymbiotic acquisition of mitochondria and plastids more than 1 Ga ago profoundly impacted eukaryote evolution. At the heart of understanding organelle evolution is the re-arrangement of the endosymbiont proteome into a host-contr...

Natural selection drove metabolic specialization of the chromatophore in <i>Paulinella chromatophora</i>
Abstract
Background
Genome degradation of host-restricted mutualistic endosymbionts has been attributed to inactivating mutations and genetic drift while genes coding for host-relevant functions are conserved by purifying selection. Unlike their...

How really ancient is <i>Paulinella chromatophora</i>?
Abstract
The ancestor of Paulinella chromatophora established a symbiotic relationship with cyanobacteria related to the Prochloroccocus/Synechococcus clade. This event has been described as a second primary endosymbiosis leading to a plastid in ...
