This strain was obtained by David Grant from Uwe G. Schlösser, Sammlung von Algenkulturen (SAG), while David was at the University of Chicago, and was brought to Duke University by him. It was originally accessioned by SAG as “Lewin Caroline Islands strain” but its chloroplast DNA is indistinguishable from that of the standard laboratory strain of C. reinhardtii. Ferris reported that its distribution of the Gulliver transposon is also consistent with its being an isolate of the standard strain.
Christoph Beck reported this strain did not mate with his 137c or CC-1373 11/86, whereas our tests showed good mating with CC-125.

CC-125 wild type mt+ [137c]
$30.00
$30.00
Boynton-Gillham laboratory, Duke University
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 R.P. 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, in contrast to CC-124, which has the agg1 allele at this locus.
CC-125 is the background strain for many mutations, including CC-503 cw92 mt+ which was the source of DNA used for genomic sequencing.

Phenotype: requires acetate, sensitive to light
Following 5-fluorodeoxyuridine treatment and ethyl-methanesulfonate mutagenesis of wild-type 2137 mt+ cells, colonies were screened for light-sensitive, acetate-requiring phenotypes (Spreitzer and Mets 1981). Mutant 11-1A displayed uniparental inheritance, and lacks photosystem II activity (Spreitzer and Mets 1981). Recombination tests showed that 11-1A is at the same locus (pst-u-1) as 8-36C, 10-4, 11-3D, 11-4D, and 12-3C (Spreitzer and Ogren 1983a). Mutants 8-36C, 11-1A, and 11-4D were shown to result from deletions in psbA (Bennoun et al 1986). However, the extent of the deletions in 11-1A and 11-4D differs from that in 8-36C and FUD7 (CC-4147) (Bennoun et al 1986). This strain was recovered from a cross between the original 11-1A mt+ (CC-2051) and pf2 mt- (from Levine), and has been maintained with acetate medium in darkness since 1980 to prevent selection for revertants and non-light-sensitive suppressors (Spreitzer and Ogren 1983b).

Phenotype: requires acetate, sensitive to light
Following 5-fluorodeoxyuridine treatment and ethyl-methanesulfonate mutagenesis of wild-type 21gr mt+ cells, colonies were screened for light-sensitive, acetate-requiring phenotypes (Spreitzer and Mets 1981). Mutant 8-36C displayed uniparental inheritance, and lacks photosystem II activity (Spreitzer and Mets 1981).

Because the 8-36C mutation was shown to be linked with a mutation conferring herbicide resistance (Galloway and Mets 1984), subsequent studies confirmed that 8-36C results from a deletion in the psbA gene similar to that of FUD7 (CC-4147) (Bennoun et al 1986).

The pg-101 or lor1 mutant was isolated by M. Tellenbach in Boschetti’s laboratory, by selecting cells with altered color after UV mutagenesis of an arg2 strain (CCAP 11/32f, Levine arg2 mt+). Tellenbach characterized it as deficient in loroxanthin. Subsequently Chunayev et al. showed that it was deficient in alpha cyclase, resulting in failure to produce the carotenoid epsilon rings.
Please see CC-2420 for additional information on this mutant.

CC-3872 pg-113 arg2 mt+
$30.00
$30.00
From Arminio Boschetti, University of Bern, August 2001
Phenotype: chlorophyll and carotenoid deficient; requires arginine
From Boschetti’s notes on this strain: The pg-113 mutant was isolated by M. Tellenbach in Boschetti’s laboratory, by selecting cells with altered color after UV mutagenesis of an arg2 strain (CCAP 11/32f, Levine arg2 mt+) and subsequently determined in collaboration with Alexander Chunayev to be an allele at the CBN1 locus although its phenotype differs somewhat from the cbn1-48 mutant that defines that locus. It lacks a stable chlorophyll complex and chlorophyll b, but has normal chlorophyll a., and the LHCII proteins are normal. The amount of neoxanthin is reduced. This strain grows phototrophically but should be kept at low to medium light intensity.
