Several changes occur in wild-type Chlamydomonas reinhardtii upon exposure to limiting CO2, including induction of several polypeptides. Polypeptide induction was previously shown to correlate with appearance of the active CO2-concentrating mechanism (CCM) of this alga. In this paper induction of polypeptides by limiting CO2 was investigated in mutants with lesions in the CCM. Mutants with lesions in the ca-1 and pmp-1 loci exhibited alterations in polypeptide induction, but it was concluded that the alterations probably do not represent their primary genetic lesions. Other changes that occur in this alga in response to limiting CO2 were also investigated. Based on a lack of significant change in the transcript abundance of ribulose-1,5-bisphosphate carboxylase/oxygenase large and small subunit genes in the wild type, it was concluded that the previously reported transient decline in synthesis of both subunits is controlled at the translational level. A transient increase in the activity of the photorespiratory enzyme phosphoglycolate phosphatase was observed in the wild type but not in a mutant, cia-5, that lacks induction of the CCM. In addition, changes in expression of genes encoding periplasmic carbonic anhydrase, a 36-kDa membrane-associated protein and a chlorophyll-binding protein occurred in the wild type but not in cia-5 in response to limiting CO2. The absence of these changes in cia-5 was attributed to a lack of either the signal itself or transduction of the signal responsible for adaptation to limiting CO2, which led to speculation that a larger range of responses are regulated by the same signal than was previously recognized. Key words: photosynthesis, photorespiration, algae, inorganic carbon transport, transcription, translation.
