Abstract

Ribosomal proteins from chloroplasts of Nicotiana tabacum L. (cv. Petit Havana) and of SRl, a mutant derived from it, with uniparentally inherited streptomycin resistance, were characterised by two-dimensional gel electrophoresis. From the 67 proteins identified, one has an altered electrophoretic mobility when isolated from the mutant. Streptomycin resistance of the SRl mutant therefore seems to be the consequence of a mutation in the chloroplast DNA coding for a chloroplast ribosomal protein.
