Differential proteomics of Lenisia limosa (Breviatea) and its epibiotic Arcobacter symbiont

ABSTRACT: The Breviatea form a lineage of free-living protists that emerged over 800 million years ago as a sister clade to opistokonta, comprising animals and fungi. Breviates conserved the ability to thrive in absence of oxygen which was an important adaptation to the low oceanic oxygen-levels that prevailed by that time. We previously found that the novel breviate, Lenisia limosa, gen. et sp. nov., was opportunistically colonized by relatives of animal-associated Arcobacter. Here we used differential proteomics to investigate how the presence/absence of symbiotic Arcobacter is manifested in Lenisia limosa's proteome. Vice versa, we also measured how symbiosis is reflected in Arcobacter's proteome. The results provide a resource to characterize the molecular underpinnings of a novel protist-prokaryote symbiosis.
