Three microsyntenic regions identified by BLASTN on Arabidopsis chromosomes. Arrows indicate Arabidopsis BAC clones with BLASTN matches for the tomato RFLP marker. MSR, microsyntenic region. Solid segments indicate the MSRs defined here. The default values for TAIR BLAST and the Blosum 62 scoring matrix were used for the BLASTN parameter options. Hatched segments on Arabidopsis chromosomes (AtCHR) 2 and 4 represent previously reported duplicated chromosomal segments [19]. LeCHR1, L. esculentum chromosome 1.
