CC-267 sr-u-sm5 (nit+) mt+

Locus: 16S rRNA, chloroplast genome

Source: From Ruth Sager, 1975

Comment: This is the primary stock of sr-u-sm5 in the Chlamydomonas Center collection. Other streptomycin resistance mutations, notably sr-u-2-60, have been more frequently used in crosses for chloroplast genetics, however.

Like most of Sager's strains, CC-267 grows on nitrate as sole N source (indicated by the nit+ or NIT allele designation). This property is in contrast to most strains from the Ebersold/Levine background, which carry the nit1 and nit2 mutations.
