Background: The purpose of this study was to sequence and assemble the tobacco mitochondrial transcriptome
and obtain a genomic-level view of steady-state RNA abundance. Plant mitochondrial genomes have a small
number of protein coding genes with large and variably sized intergenic spaces. In the tobacco mitogenome these
intergenic spaces contain numerous open reading frames (ORFs) with no clear function.
