a, Waterfall plot showing the syntenic relationships between LAB, QLD and other related species as generated by SynVisio. b, Fraction of orthologous gene clusters in different Solanaceae chromosomes, highlighting a high conservation of chromosomes 1–4, and a declining conservation of remaining chromosomes; chromosome numbering largely follows the tomato–potato system. N.b., N. benthamiana. c, A Gibson Venn diagram showing the number of gene family clusters that are shared among LAB, N. sylvestris and N. glauca. d, Overlay of N. glauca (blue bars within chromosomes) and N. sylvestris (red) orthologous genes on LAB chromosomes. Grey/blue lines connecting chromosomes link syntenic blocks among the matched subgenome chromosomes. e, Circos plot of the physical distribution of syntenic blocks of tomato chromosomes 9–12 overlaid onto the LAB genome (track a), showing extensive fragmentation across the remaining LAB chromosomes. By contrast, an overlay of the syntenic blocks of tomato chromosomes 1–4 onto the LAB genome clearly demonstrates the conservation of both sequence and ___location (track b). Track c shows the gene density across the LAB chromosomes.
