From: A DArT marker-based linkage map for wild potato Solanum bulbocastanum facilitates structural comparisons between SolanumA and B genomes

LG/chromosome ( S. bulbocastanum ) Potato Tomato 1 Position in tomato genome (Mb)
DArT 2 BAC FISH 3
2 2S inversion 2S inversion 15.4 - 31.9 -
  2 L inversion 43.8 - 47.9 43.9 - 47.5
3   3S translocation 1.8 - 7.7 -
5   5S inversion 0.5 - 5.1 0.4 - 5.0
6   6S inversion 1.9 - 2.2 1.9 - 2.4
8 8S inversion 8S inversion 1.1 - 2.5 -
9   9S inversion 0.8 - 5.1 0.7 - 6.1
11   11S inversion 4.2 - 5.1 0.1 - 5.2

  1. 1Bold characters indicate chromosomal structural rearrangements previously identified between potato and tomato genomes as indicated in Table 1.
  2. 2identified based on alignment of DArT sequences (mapped in S. bulbocastanum consensus linkage map) flanking chromosomal rearrangements to tomato genome sequence.
  3. 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].
