A point mutation in the chloroplast 16 S rRNA gene of a streptomycin resistant Nicotiana tabacum

We sequenced a 82 bp fragment in the chloroplast 16 S rRNA gene of the streptomycin resistant mutant SR1 of Nicotiana tabacum. The sequence contains a transition from cytosine to adenine in position 860 of the 16 S rRNA. We suggest that this mutation is sufficient for the streptomycin resistance phenotype in the SR1 mutant.
