Ribosomal proteins in plastids of a mendelian and a nonmendelian streptomycin-resistant mutant of Chlamydomonas reinhardii determined by two-dimensional gel-electrophoresis

The pattern of ribosomal proteins in plastids of a nonmendelian streptomycin resistant mutant does not differ from that of wildtype cells when compared by two-dimensional gel-electrophoresis. The protein pattern of a mendelian resistance mutant is changed, however.Since the resistance in this mendelian mutant is probably caused by a change in the ribosomal proteins, the resistance in the nonmendelian mutant must be considered as a change of the ribosomal RNA.This work was supported by the Deutsche Forschungsgemeinschaft.
