Expression of gene transcripts and OR transcripts. Grouping of total gene transcripts and OR transcripts into three categories: expressed, weakly expressed and not expressed. For 39,308 of the 41,012 unique probes on the array, an accession number is given in GenBank and Ensembl [45]. They correspond to 23,642 unique transcripts or genes, including 1136 OR genes. The ratios of expressed transcripts over not expressed transcripts and of expressed OR genes over not expressed OR genes are 2.75 and 3.36, respectively.
