Phenotype: chlorophyll deficient

This strain was derived as follows:

CC-373, an atpB deletion mutant, was transformed with the wild-type Chlamydomonas atpB gene to produce CC-3452, which was used as a control for CC-3453, CC-3454, and CC-3455 containing the same atpB gene upstream of three versions of the E. coli recA gene. (These strains are no longer in the collection.)

CC-3452 was then crossed to CC-1930 arg2 mt-, and a wild-type progeny clone (i.e. not requiring arginine) was seleted, to yield CC-3456.

CC-3456 was then transformed with an aadA construct disrupting the chlL gene (Goldschmidt-Clermont), flanked by direct repeats to evaluate recombination frequencies in the chloroplast. CC-3460 is one of the transformants recovered.

Phenotype: chlorophyll deficient

Derivation of this strain was parallel to that of CC-3460, beginning with CC-3455, which was crossed to CC-1930 to give CC-3459 mt-, which was then transformed with the chlL disruption as in CC-3460.

This strain was derived by transformation of CC-124 wild type mt- with an RbcS2::aadA::RbcS2 construct (P-681) as described by Cerutti et al. (1997a). This strain was characterized as having an unstable spectinomycin resistance phenotype.

Chlamydomonas Genetics Center, Duke University, 1997

Phenotype: wall deficient

From a series of four backcrosses of CC-125 wild type mt+ to obtain a better cw15 mt- isolate, beginning with CC-406.

This cell wall deficient strain swims and mates better than its parent CC-406. However, all cw15 cultures typically contain a high proportion of non-flagellated cells.

From Robert Drager and David Stern, Cornell University, December 1997

This is a transformant of the atpB deletion mutant strain CC-373 with pDG2, which contains the E. coli uidA (GUS) gene flanked by the Chlamydomonas petD promoter and rbcL 3′ UTR.
