Strains

From Rene Matagne, University of Liege, June 1984

Phenotype: requires arginine

The arg7-12 mutation was induced by Matagne using nitrosoguanidine.

This allele can complement with the original arg7, arg7-5, arg7-8 (aka arg2), and arg7-13. It cannot complement with arg7-2, arg7-3, arg7-4, or arg7-7. It seems to be stable.

The following citation refers specifically to arg7-12:

From Martin Spalding, Iowa State University, October 1984

Phenotype: altered CO2 assimilation

This strain requires high CO2 concentrations for phototrophic growth. We maintain this strain in dim light.

Originally pmp-1-16-5k, this mutant was induced by 5-fluorodeoxyuridine plus ethyl methanesulfonate in the 2137 strain (see CC-3269). The pmp1 mutant is defective in inorganic carbon transport, and requires high CO2 concentrations for phototrophic growth. The pmp1 and ad (air-dier) mutants are alleles at the LCIB locus.

For more information on the ca1 mutation, which is in the CAH3 gene, please see CC-1219, and for reference citations for pmp1, please see CC-1860.
