Figure 7.

Sequences of pea cox2 promoters. The sequences surrounding the three different 5′ ends of pea cox2 transcripts [pcox2 (1–3)] are aligned with the –14 to +4 promoter sequence located upstream of the pea atp9 (patp9) gene. Whereas sequences at sites 2 and 3 were aligned for best nucleotide consistence with the pea atp9 promoter, the sequence at site 1 is aligned with respect to the detected 5′ ends (indicated by bent arrows). Nucleotide positions are given for the pea atp9 promoter referring to the transcription start site (+1). The AT-rich region (AT-Box, –14 to –8) and the CNM (–7 to +2) as well as purine-rich nucleotide positions +3/+4, all hallmarks of the CNM-type dicot plant mitochondrial promoters, are boxed and highlighted.
