Green algae (Chlorophyta) are a morphologically heterogeneous group that is undergoing considerable revisions at present. Especially in coccoid genera, there have been striking cases of polyphyly, when species originally placed in one genus were shown to belong to up to three different classes. The coccoid chlorophycean genus Bracteacoccus Tereg was until recently considered monophyletic, but with the advent of new molecular data, it no longer appears as such. The goal of my project is to monograph the genus Bracteacoccus. I collect 18S ribosomal DNA sequences (nuclear gene) as well as rbcL sequences (chloroplast, protein-coding gene).
