Fig. 2: Biogeography of Phaeocystis spp. with respect to size fractions.
From: Genome-resolved biogeography of Phaeocystales, cosmopolitan bloom-forming algae
a The isolation sites of CCMP accessions and their biogeography, based on genome-wide Tara Oceans metagenomic read mapping, normalized to library size, expressed as reads per million (RPM). Data includes numbers for Phaeocystales MAGs37. For each oceanic domain, multi-level pie charts are shown, with inner circles representing the contributions of each Phaeocystis spp. to the total read abundance, and outer circles representing the proportions of reads from different size fractions mapping to these species, clockwise according to the color legend. In most oceanic domains, Phaeocystis spp. occur as flagellates among nano- and picoplankton. b Copies per liter (CPL) abundance of 18S-V4 of Phaeocystis OTUs in the CalCOFI/NCOG data. c Loge of the ratio of mitochondria- and plastid-mapping reads for Phaeocystis spp. where both organellar genomes are available. Left panel plots globosa genotypes, right all other species. Thicker lines mark the three species with the highest number of mitochondrial-mapping reads, P. antarctica, P. cordata and P. globosa genotype 2. Note a somewhat bimodal distribution for P. cordata, suggesting higher mitochondrial activity is condition specific. Source data are provided as a Source Data file.
