Extended Data Fig. 2: Dinoflagellate taxonomic annotations across the transect.

From: Dinoflagellates alter their carbon and nutrient metabolic strategies across environmental gradients in the central Pacific Ocean

Extended Data Fig. 2

a, Dinoflagellate family-level and (b) genus-level relative community composition determined through 18S rRNA, metatranscriptomic and metaproteomic analyses from 3-51 µm filter fractions, highlighting the abundance of the Kareniaceae-like family and Karlodinium and Karenia-like genera in transcripts and proteins. Taxonomic annotations were assigned based on assembled metatranscriptome matches to the PhyloDB database, containing marine protistan21 and bacterial transcriptomes and genomes. 18S rRNA annotations were assigned using the PR2,22 database. ‘NA’ represents dinoflagellate OTUs without family or genera-level taxonomy available in the PR2 database. In the transcript pool, Karenia and Karlodinium genera together comprised an average 42 ± 0.02% of the total dinoflagellate reads in the euphotic zone (< 200m) and 42 ± 0.04% in the mesopelagic (≥ 200m). In the protein pool, these two genera comprised an average 45 ± 10% of the spectral counts in the euphotic zone and 71 ± 12% in the mesopelagic.
