Proteomic and biochemical responses to different concentrations of CO₂ suggest the existence of multiple carbon metabolism strategies in Phaeodactylum tricornutum.

ABSTRACT:

Background

Diatoms are well known for high photosynthetic efficiency and rapid growth rate, which are not only important oceanic primary producer, but also ideal feedstock for microalgae industrialization. Their high success is mainly due to the rapid response of photosynthesis to inorganic carbon fluctuations. Thus, an in-depth understanding of the photosynthetic carbon fixation mechanism of diatoms will be of great help to microalgae-based applications. This work directed toward the analysis of whether C4 photosynthetic pathway functions in the model marine diatom Phaeodactylum tricornutum, which possesses biophysical CO₂-concentrating mechanism (CCM) as well as metabolic enzymes potentially involved in C4 photosynthetic pathway.
