外文摘要：Gene encoding for alpha-carbonic anhydrases (alpha-CAs) and their functions in fundamental metabolism and biomineralization are widely identified in mollusks. However, the transcriptional regulation of alpha-CA genes in response to various environmental conditions remains unknown. In the present study, we characterized a cDNA encoding for an alpha-CA (HcCA) from the freshwater pearl mussel Hyriopsis cumingii. The spatial and temporal expression patterns of HcCA indicate that this gene is mainly expressed in the mantle of juvenile mussels. The expression profile of HcCA under various environmental conditions reveals that the transcription of HcCA is significantly regulated by Ca2+ concentration, water temperature, pH and air exposure. Our results suggest that HcCA is a crucial target gene by which the external environmental conditions affecting shell growth and pH homeostasis of H. cumingii. (C) 2014 Elsevier B.V.
