Figure 4

Distribution gradient of telo boxes along the direction of transcription in Arabidopsis. Location of telo boxes within Arabidopsis genes is estimated from the TAIR database (TAIR9 CDS+UTRs+introns datasets); frequency of appearance of telo boxes within Arabidopsis introns from the TAIR9 introns datasets. Dm is the % of motifs found within a given intron relative to the total number of motifs observed within the Arabidopsis introns (TAIR database, introns). Di is the % of introns at a given position (intron 1, 2, 3...) relative to the estimated total number of introns.
