CC-99 sr-u-sm3a mt+

Boynton-Gillham laboratory, Duke University

Phenotype: antibiotic resistant (streptomycin)

This is a haploid derivative of the original sr-u-sm-3a strain, which was a diploid. The streptomycin resistance results from a mutation in the gene encoding chloroplast 16S rRNA. This mutation is unique among chloroplast sr mutants examined in having an alteration in the extreme 5′ end of the 16S rRNA molecule (U -> G at nt 14, corresponding to E. coli 13)
