Identification of 13 Orthologous Regions between Rice and Wheat.

(A) Schematic representation of the 13 orthologous regions identified between rice (r1 to r12) and wheat (w1 to w7) chromosomes. The 1108 pairs of orthologous genes are depicted as thin blue lines.

(B) Schematic representation of the 149 orthologs (vertical lines) identified between wheat chromosome 3B (w3B) and rice chromosome 1 (r1). Different colored blocks represent the colinear regions identified between r1 and w3B. Rearrangements between orthologous genes are highlighted with red lines. Two large inversions of colinear regions are indicated with arrows above and below the wheat and rice chromosomes, respectively. Wheat deletion bins are indicated above the 3B chromosome, whereas rice chromosome 1 is divided into 10-Mb segments.
