Figure 1.
Physical linkage map of the tomato genome.
Twelve linkage groups were constructed using 829 SSR markers (SSRs) and 96 RFLP markers (RFLPs). The names of the SSRs are marked to the right of each chromosome and the inter-distance in kb between each two adjacent SSRs is marked on the left. The Inter-distance in the figure means the physical distance between each two adjacent SSR markers and the black bar under inter-distances highlights some very large inter-distances with measurement unit Mb instead of kb. The markers in the bold font are the 96 RFLPs from the Tomato IL Map on the Sol Genomics Network (http://sgn.cornell.edu/), and the 179 SSRs investigated previously undefined segments in 75 introgression lines from the cross between cv. M82 (S. lycopersicum) × LA0716 (S. pennellii). The thick black bar indicates the presumed heterochomatin region, between two SSRs marked with *. Euchromatin and heterochromatin regions were estimated based on previous reports and the released sequence data of the tomato genome on the Sol Genomics Network (http://sgn.cornell.edu/). The SSR loci adopted from Tomato-EXPEN2000 Map [29] and the linkage map constructed by Shirasawa et al. [30] were marked with red and green color, respectively.
Figure 2.
Linkage map of introgressions in 75 introgression lines (ILs) from the cross between cv. M82 (S. lycopersicum) × LA0716 (S. pennellii).
Twelve linkage groups were constructed using 96 RFLP markers (RFLPs) from the Tomato IL Map on the Sol Genomics Network (http://sgn.cornell.edu/) and 168 SSR markers (SSRs) used to define the ends of each introgression and previously undefined loci in 75 introgression lines (ILs). The bars in the right side indicate the introgression segments in the ILs. The furthest short bars in the right side of each chromosome indicate the previously undefined DNA segments. The inter-distance in kb between each two adjacent SSRs is marked on the left. The black bar under the inter-distances highlights some very large inter-distances with measurement unit Mb instead of kb. The thick black bar indicates presumed heterochromatin region between two SSRs marked with *. Euchromatin and heterochromatin regions were estimated based on previous reports and the released sequence data of the tomato genome on the Sol Genomics Network (http://sgn.cornell.edu/). The SSR loci marked with red color were adopted from Tomato-EXPEN2000 Map [29], and the SSRs with green color were shared by the linkage map developed by Shirasawa et al. [30].
