Changes in phosphatase activity associated with cell wall defects in Chlamydomonas reinhardi

R Loppes et al. Arch Microbiol. .

Abstract

Experiments were performed to isolate mutants lacking alkaline phosphatase in Chlamydomonas reinhardi. Mutants with null enzyme activity were obtained. A cytological study of these mutants however revealed cell wall defects, suggesting that the loss of phosphatase activity in these strains is not due to the inactivation of the corresponding phosphatase structural gene but rather to the leakage of this enzyme as a consequence of the cell wall abnormality. Incidentally, this finding provides the basis of a convenient method for selecting easily cell wall mutants of Chlamydomonas.
