CC-125 wild type mt+ 137c

Source: R.P. Levine via N.W. Gillham, 1968

Comment: This is the basic "137c" wild type strain originally from G.M. Smith, isolated in 1945 near Amherst MA, and is presumably equivalent to strain 11/32c of the Culture Centre of Algae and Protozoa. This particular strain was brought to Duke by N.W. Gillham in 1968 from Levine's laboratory at Harvard. CC-124 and CC-125 carry the nit1 and nit2 mutations, and cannot grow on nitrate as their sole N source. CC-125 carries the AGG1 (agg1+) allele for phototactic aggregation; see The Chlamydomonas Sourcebook [Harris (1989)], p. 215. Contrast CC-124, which has the agg1 allele at this locus.

Comment: CC-125 is the background strain for many mutations, and is a good control for most purposes.
