Comparison of the DSYB (A) and Alma1 (B) relative gene expression per sample (x-axis) and per MGT (y-axis) across samples. Numbers near each point represent a Tara Oceans station. (SRF) Surface, (DCM) deep chlorophyll maximum. Y-axis (to the left of panel A) and size fractionation (to the right of panel B) are common for both figures. Tara Oceans provinces are applicable to both graphs and are specified on the right side of panel B. (ATLN) North Atlantic Ocean, (ATLS) South Atlantic Ocean, (SO) Southern Ocean, (INDIAN) Indian Ocean, (MEDIT) Mediterranean Sea, (PACN) North Pacific Ocean, and (PACS) South Pacific Ocean. (A) DSYB expression profiles across Tara Oceans stations and size fractions for 10 MGTs contributing significantly to the overall DSYB expression (at least 10% of the total DSYB expression in at least one sample). Red circles (MGT-4 and MGT-13) represent MGTs taxonomically assigned to the genus Phaeocystis; green circles (MGT-44, MGT-166, and MGT-179) represent Chloropicophyceae-affiliated MGTs; the rest of the circles represent other organisms. (B) Alma1 expression profiles across Tara Oceans stations and size fractions for nine MGTs contributing significantly to the overall Alma1 expression (at least 10% of the total Alma1 expression in at least one sample). Red circles (MGT-4, MGT-13, and MGT-67) represent MGTs taxonomically assigned to the genus Phaeocystis; yellow circles (MGT-178) represent Pelagomonas spp.-affiliated MGTs; and the rest of the circles represent other organisms.
