Linear graphical representation of BLAST (blastN) search against Arabidopsis genome. Each element represents a spliced gene region (TIGR version, May 2003). Elements ordered according to position on chromosome and are web links to corresponding entries in CGP database. Color intensity indicates level of similarity (normalized Expectation values = -log(Exp)). Green - significant hit to lettuce, Red - significant hit to sunflower. Yellow - significant hit to both. White blocks separate the Arabidopsis chromosomes.
