pubmed:abstractText |
Ac-208, a plastocyanin-deficient strain of Chlamydomonas reinhardtii, lacks the mRNA for pre-apoplastocyanin although Southern analyses indicate no gross deletion in the single gene for pre-apoplastocyanin. The alternative electron carrier, cytochrome c-552, is expressed only in Cu(II)-deficient cells of the mutant. Thus, the mutant strain can grow photoautotrophically in Cu(II)-deficient but not in Cu(II)-sufficient medium. This indicates that the absence of plastocyanin is the only defect (with respect to photosynthesis) in ac-208. Phenotypic revertants of ac-208 are capable of photoautotrophic growth by virtue of constitutive [with respect to Cu(II)] synthesis of cytochrome c-552. The revertant phenotype is attributed to a decreased internal concentration of Cu(II). This indicates that the Cu(II)-dependent expression of cytochrome c-552 synthesis is affected directly by the concentration of Cu(II) rather than indirectly by the level of plastocyanin in the cell.
