Intersection of MPSS tags and TARs from tiling microarray for Arabidopsis and rice. Figure 1A shows the percentage of transcripts that are identified by both the technologies. GATC-TARs represent the percentage over the subset of TARs that contain at least one GATC motif, the recognition site for the anchoring enzyme DpnII used in MPSS sequencing protocol. Figure 1B shows the distribution in percentage of the transcripts that are identified by both the technologies among five classes of genomic features, viz. exon, anti-exon, intron, anti-intron and intergenic.
