【 摘 要 】

Carbon physiology of a genetically identified Ulva rigida was investigated under different CO_2(aq) and light levels. The study was designed to answer whether (1) light or exogenous inorganic carbon (Ci) pool is driving growth; and (2) elevated CO_2(aq) concentration under ocean acidification (OA) will downregulate CA_ext-mediated
