Figures

FIG. 1.
FIG. 1.
Model for inorganic carbon acquisition by cyanobacteria. This model is based on the article by Woodger et al. (102). Most cyanobacteria do not contain all of the transporters depicted. In addition, any given cyanobacteria would have only one type of carboxysome (alpha or beta), although both pathways are shown in this figure.
FIG. 2.
FIG. 2.
Model of the CCM of Chlamydomonas reinhardtii. The figure depicts an algal cell with a single chloroplast containing a single pyrenoid. As indicated by the size of the lettering, the concentrations of bicarbonate and carbon dioxide within the chloroplast and pyrenoid are higher than those in the external environment. CAH1, CAH3, CAH6, CAH8, and CAH9 stand for specific CA isoforms. PGA, 3-phosphoglyceric acid; PM, plasma membrane; CE, chloroplast envelope; TM, thylakoid membrane. The filled circles indicate possible bicarbonate (or Ci) transporters, and the closed diamonds indicate the photosynthetic electron transport chain.
FIG. 3.
FIG. 3.
Representative pyrenoids (P) from C. reinhardtii cells acclimated to high CO2 (A) or low CO2 (B). The white areas in the micrographs are starch. Bars, 1 μm.
