CC-87 nr-u-2-1 mt-

Locus: 16S rRNA, chloroplast genome

Source: Product from a cross of CC-86 nr-u-2-1 mt+ x arg2 mt-. This stock is not arginine-requiring.

Comment: This is a useful chloroplast marker, mapping to the 3' end of the chloroplast 16S ribosomal RNA. Although isolated initially as a neamine-resistant strain, it is also resistant to kanamycin, a more readily available antibiotic.
