Figure 2.

Wheel representation of synteny between pseudomolecule sequence of Medicago truncatula chromosomes Mt1-Mt8 and the consensus Vf linkage map (Vf1–Vf6). Syntenic relationships were as described in Webb et al. (2016) and re-drawn for this figure using “Circos” software (Krzywinski et al., 2009). Link lines to Medicago orthologs for markers on each Vf chromosome are shown in a different color. The virtually uninterrupted collinearity between the whole of Vf 3 and the whole of Mt1 is highlighted by representing these orthologous chromosomes in green. To illustrate how useful this syntenic framework is for translational genomics as well as for drawing together knowledge of the genome, three exemplar loci where there is a proven or presumed orthologous relationship are shown as red ticks on the orthologous chromosomes and linked by black lines. These are: the mapped ZT1 locus and its Medicago ortholog MtWD40-1, the mapped genetic interval corresponding to the mapped VC (vicine-convicine) locus and its corresponding Medicago syntenic interval on Mt2, and the actual position of the Medicago Terminal Flower Locus 1 (TFL1) with a link drawn to the region of Vf 1 where it is presumed the Vf ortholog (VfTFL1) is likely to be located.
