The comparison of mt transcription profiles and Southern-RFLP patterns in a Kov52 sibship. Total RNA was transferred to the membrane and hybridized with DIG labeled atp1 (A) or cox1 (B) probes. Ribosomal RNA stained by Ethidium bromide and corresponding to particular RNA samples is shown above cox1 transcript profile. DNA was digested with HindIII and hybridized with DIG labeled atp1(C) or cox1 (D) probes. The numbers denote individual plants. The plant 23* shows both different RFLP pattern and transcription profile from its siblings. S - DNA or RNA molecular size marker.
