Repeat families common to P. sativum , G. max and M. truncatula genomes. A. Proportion of sequences shared between pea (P. sativum) and soybean (G. max). The graph shows percentage of 454 reads with significant similarity to sequences from the other species. The contribution of various repeat families is displayed in different colors as indicated on the legend. B-D. Repeat families conserved between pea and soybean (B), soybean and M. truncatula (C), and pea and M. truncatula (D). Dots on the scatter plots represent 454 reads from one species with similarity to sequences from the other species. Positions of the dots along the axes correspond to the number of significant hits obtained for each 454 read and to their average similarity expressed as BLAST bit score. Repeat families are displayed in the same colors as on panel A; rDNA and unidentified sequences were omitted from panels C and D.
