Promoter Sequences in Arabidopsis Mitochondria.

The list includes promoters identified previously (Kühn et al., 2005) and in this study; sequences have been sorted according to the presence of a CATA, CGTA, TCTA, ATTA, AGTA, or GGTA tetranucleotide (bold black) immediately upstream of the TSS (underlined). The motif TATATA, which is recurring in mitochondrial promoters, is highlighted. The names of promoters of genes showing reduced transcription in rpoTmp mutants are printed red. The tetranucleotide GAAA, which is overrepresented in this subset of promoters, is printed green. Promoters displaying a perfect CGTATATAA or CATAAGAA motif are marked with an asterisk.
