Figure 1

Representation of candidate collinearity discontinuities within the A. thaliana genome with respect to B. rapa. The plot is divided into cells with dimensions proportional to the physical lengths of the five Arabidopsis pseudochromosomes (numbered on axes). A blue square within a cell signifies an association between 500 kb bins requiring (a.) 2; (b.) 3 or (c.) 4 distinct instances of disjoined B. rapa BES mate-pair mappings linking them.
