Algal Symbiont Diversity and Host Fitness Variation in Amoebozoan Photosymbiosis.

ABSTRACT: Photosymbioses, the symbiotic relationships between microalgae and non-photosynthetic eukaryotes, are sporadically found in many eukaryotic lineages. Only a few taxa, such as cnidarians and ciliates hosting algal endosymbionts, have been actively studied, which has hindered understanding the universal mechanisms of photosymbiosis establishment. In Amoebozoa, few species are reported as photosymbiotic, and how the photosymbioses are established is still unclear. To investigate the extent to which one of the photosymbiotic amoebae, Mayorella viridis, depends on their symbionts, the amoebae were treated with reagents known to induce the collapsing of photosymbioses in other species. We succeeded in removing algal symbionts from the hosts with 2-amino-3-chloro-1,4-naphthoquinone. While the apo
