Abstract
We analyzed the ability of plant mitochondria to process introduced RNA Arabidopsis thaliana cox2 transcripts were synthesized in vitro The in vitro transcribed mRNA was electroporated into maize and cauliflower mitochondria and incubated in organello RNA was isolated and RTPCR was carried out to analyze RNA processing Our data indicate that cox2 transcripts introduced into isolated plant mitochondria are processed completely This is the first report of in organello editing of introduced transcripts We also found that none of the transcription translation or respiration inhibitors we used influenced RNA splicing or RNA editing of the cox2 transcript Thus our data also demonstrate that plant mitochondrial RNA processing may be independent of both transcription and respiratory regulationThis work was supported by a grant from the DFG Ke409/152 We thank Mrs Hanna Schmidt for her excellent technical assistance and Prof Dr U Kück Bochum for critical discussion English language editing of the manuscript was performed by “San Francisco Edit”
