Figure S2 - Chromosomal rearrangements in the genomes of eggplant, pepper and Nicotiana with respect to the tomato genome. Genetic maps are modified from published work [9-11] with kind permission from Springer Science+Business Media. E1-12 represents the 12 eggplant chromosomes, P1-12 for pepper, and N1-12 for the MRCA of N. tomentosiformis and N. acuminata. Each tomato chromosome is assigned a different color (see color codes in the figure) and the orthologous chromosome segment(s) in eggplant, pepper and Nicotiana are painted with the same color. Putative centromere positions of eggplant and pepper chromosomes are based on their synteny with tomato and indicated by a white dot. It was not possible to determine the centromere positions for the Nicotiana chromosomes due to complex syntenic relationships with tomato. An arrow beside a chromosome indicates an inversion relative to tomato. A black bar indicates the breakpoint region of a translocation, and the chromosome is divided into segments (a-c) accordingly to facilitate comparisons of multiple species. The marker pair used to define the breakpoint region (i.e. the two adjacent markers mapped to different tomato chromosomes) or to define the borders of an inversion is highlighted in red. The map of the MRCA of N. tomentosiformis and N. acuminata is deduced based on the comparative maps of N. tomentosiformis, N. acuminata and tomato, and is not presented directly. The actual N. tomentosiformis map is presented, and the four inversions relative to its MRCA are indicated by dash arrows and the border markers are underlined.
