Homologous alignments of 4 indigoteroid genomes with Medicago truncatula as reference

  With Medicago truncatula as reference genome, genomic paralogy, orthology and outparalogy informations within and among 4 legumes from indigoteroid (Cajanus cajan, Vigna angularis, Vigna radiata and Phaseolus vulgaris) were displayed in 10 circles: The curved lines within inner circle, colored by eudicot ancestoral 7 chromosomes (Jaillon et al. 2007), linked paralog pairs on Medicago truncatula 8 chromosomes produced by LCT. The short lines forming the innermost circles represents all predicted genes in Medicago truncaluta, which have one paralogous regions, forming another circle. Each of the two sets of Medicago truncaluta paralogous chromosomal regions have one orthologous copies in a legume with exception of soybean, which would have 2. Therefore, 4 legumes genome will result in 22 circles in the figure. Each circle is colored as to its source plant corresponding to the color scheme in Fig. 1. Homologous genes donoted by shot lines standing on a chromosome circle, and colored as to its chromosome number in the source plant shown in the inset legend.
