Figure 1.
Relative abundance of substrate-stained cells and FISH identification of substrate-stained cells in incubations of seawater from five stations of different provinces of the Atlantic Ocean (see Supplementary Figure S1 for station locations). (a) relative abundance of cells stained by laminarin (yellow), xylan (red) and chondroitin sulphate (blue). Incubation time is indicated by ‘T’ (0–18 days). T0 refers to samples taken approximately 30 min after addition of the FLA-PS. (b) Relative abundance of laminarin-stained cells and fraction stained by FISH probes for Bacteroidetes (CF319a), Planctomycetes (PLA46) and Catenovulum (CAT653). (c) Relative abundance of xylan-stained cells and fraction stained by FISH probes for Bacteroidetes (CF319a), Planctomycetes (PLA46) and Catenovulum (CAT653). (d) Relative abundance of chondroitin-stained cells and fraction stained by FISH probes for Bacteroidetes (CF319a), Planctomycetes (PLA46) and Catenovulum (CAT653).
