Number of transcripts and the average number of transcripts per gene are based on the total number of genes (TAIR10, AtRTD1 and AtRTD2) or the total number of genes detected (8) or on protein-coding genes (Araport11 and AtRTD2).

^aContains redundant partial transcripts which differ only by lengths of 5΄ and 3΄ UTRs.

^bMerged, non-redundant transcripts.
