Cooperation between passive and active silicon transporters clarifies the ecophysiology and evolution of biosilicification in sponges
ABSTRACT The biological utilization of dissolved silicon (DSi) influences ocean ecology and biogeochemistry. In the deep sea, hexactinellid sponges are major DSi consumers that remain poorly understood. Their DSi consumption departs from the Michaelis-Menten kinetics of shallow-water demosponges and...
