CC-425 arg2 cw15 sr-u-2-60 mt+
Locus: ARG7, linkage group I
Locus: CW15, linkage group unknown
Locus: 16S rRNA, chloroplast genome

Comment: This strain has been used frequently in transformation experiments with the ARG7 gene. The cw15 background facilitates transformation; the chloroplast sr-u-2-60 marker is irrelevant for this purpose. Transformation frequencies are good, but several people have reported difficulties in getting complete tetrads in subsequent crosses for transformants.
