¹Bold characters indicate chromosomal structural rearrangements previously identified between potato and tomato genomes as indicated in Table 1.
²identified based on alignment of DArT sequences (mapped in S. bulbocastanum consensus linkage map) flanking chromosomal rearrangements to tomato genome sequence.
³identified based on alignment of sequenced BAC clones to tomato genome sequence. The BAC clones flank chromosomal rearrangements used in cytological study by Peters et al. [26], Szinay et al. [28] and Iovene et al. [29].
