CC-110 spr-u-1-6-2 mt+ Locus: 16S rRNA, chloroplast genome
Source: Derived at Duke from a cross between CC-147 nr1-8 spr-u-1-62 and CC-198 er-u-37 sr-u-2-60; does not carry nr1-8 or the markers from CC-198.
Comment: This is a good chloroplast resistance marker, easy to score on 100 microgram/ml spectinomycin.
