Sources of organic material in the deep ocean and relative abundance of transport proteins. Heterotrophic microbes use dissolved organic material (DOM1) released by phytoplankton in the surface layer. Below the euphotic zone, microbes can use DOM exported to deep waters (DOM2) or DOM from the solubilization of sinking organisms and detritus. The composition of the organic material may be substantially modified during its descent or after solubilization (DOM3) or it may resemble DOM in the surface layer (DOM1). Dashed lines indicate that the several processes are likely needed to produce DOM. The bar graphs give the relative abundance (± SD of two to four samples) of ABC transporters for the indicated compounds based on data in figure 4 of Bergauer et al. (1). Amines, spermidine and putrescine; Pro-GlyBet, proline and glycine betaine.
