Illustration of conserved Arabidopsis genome sequence (CAGS). (A) CAGS with single Brassica matches. Thin lines represent Brassica–Arabidopsis HSPs; thick bars, the corresponding Arabidopsis genomic sequence. (B) Overlapping Brassica matches (HSPs) are merged to produce one CAGS for that region. (C) CAGS chains. Intergenic CAGSs that fall within 416 bp of one another were chained together to represent a single feature. Open boxes between CAGS represent regions <416 bp that may correspond to introns between CAGS.
