Rice mitochondrial transcriptome. (A) Tissue-specific plot of mean RNA expression level. Each dot represents each genic region. Housekeeping genes are known mitochondrial genes such as subunits of ATP synthetase, cytochrome oxidase or ribosomal proteins. Inter-genic ORFs are ORFs located between known housekeeping genes. (B) Confidence of expression of each type of regions. Each box represents the expressional confidence level (p- values by Student's t-test) as described in Methods. For simplicity of the figure, 8000 probes at even intervals were selected from the entire genome for display. Selected probes were categorized into three types, depending on which region of the genome they were located on (housekeeping genes, inter-genic ORF region or region without any ORFs predicted). Probes were arranged in descending order of expressional confidence in seedlings, for each category of genomic regions (housekeeping genes, inter-genic ORFs and other regions).
