CC-198 er-u-37 sr-u-2-60 mt-

Locus: 16S rRNA, chloroplast genome
Locus: 23S rRNA, chloroplast genome

Source: From a cross of nr-u-2-1 sr-u-2-60 spr-u-1-H-4 mt+ to CC-67 er-u-37 mt-, Boynton-Gillham lab at Duke; derived from progeny of a spontaneous biparental zygote.

Comment: This recombinant product does not carry either the nr-u-2-1 or spr-u-1-H-4 markers. It has been used extensively in genetic analysis at Duke and is a good choice when a strain with two easily distinguished antibiotic resistance markers is desired.
