Identification of Neurospora mitochondrial promoters and analysis of synthesis of the mitochondrial small rRNA in wild-type and the promoter mutant [poky].

Abstract excerpt

Using an in vitro transcription assay, we previously identified promoters in Neurospora mtDNA at the 5' ends of the genes encoding the mitochondrial (mt) small and large rRNAs and cob pre-mRNA. Here, we identified two additional promoters in mtDNA restriction fragment EcoRI-6, 3.8 and 5.5 kilobases upstream of the 5' end of the mt small rRNA. By comparing the two new promoters with the three identified...
