Taxonomic assignent of diatom symbionts. Proteome-based clustering approaches reveal phylogenetic insights into Amphistegina

Different proteomics-based approaches were applied using novo peptide sequencing and similarity clustering to several populations of the large benthic foraminifera Amphistegina lobifera, A. lessonii and A. gibbosa. To differentiate the contribution of the symbiont community to the proteome, 18S sequences were used to classify the algae symbionts in the host.
