Cells of the marine diatom Phaeodactylum tricornutum Bohlin (UTEX 642) grown in 5% CO2 were transferred to air-level CO2 in the light or dark and allowed to acclimate to air. No accumulation of the transcript of the P. tricornutum β-carbonic anhydrase 1 (ptca1) was detected in 5% CO2-grown cells, but ptca1 mRNA accumulated and reached a peak after 6 h acclimation to air but decreased over the next 18 h. A similar accumulation time course was observed in cells air-acclimated in the dark, ...

An anaplerotic role for mitochondrial carbonic anhydrase in Chlamydomonas reinhardtii1
Plant Physiology ; Previous studies of the mitochondrial carbonic anhydrase (mtCA) of Chlamydomonas reinhardtii showed that expression of the two genes encoding this enzyme activity required photosynthetically active radiation and a low CO2 concentration. These studies suggested that the mtCA was involved in the
Carbonic Anhydrase and Alveolar Fluid Absorption/From the Authors
American Journal of Respiratory Cell and Molecular Biology ; To the Editor: The recent article by Chen and coworkers (1) reports that carbonic anhydrase II (CAII) is found in both type I and type II alveolar epithelial cells. Although inhibition of CAII with acetazolamide or methazolamide delayed intracellular acidification during hypercapnia in cultured
