Figure 2: Synteny between Nicotiana tabacum, Nicotiana tomentosiformis and Nicotiana acuminata genetic linkage groups and tomato chromosomes.
From: The tobacco genome sequence and its comparison with those of tomato and potato

Links between tomato and tobacco are based on the mapping of tomato proteins to linkage group-anchored tobacco sequences. Note that not all regions identified by this method should necessarily be considered as syntenic. Links between tobacco and N. tomentosiformis (red) and N. acuminata (blue) are based on shared SSR (full lines) and COSII (dotted lines) markers. Triangles indicate the amplification of the corresponding SSR in N. tomentosiformis (red) or N. sylvestris (blue).
