Figure 6From: Sequence and structure of Brassica rapachromosome A3Genome building blocks and block boundaries of the ancestral karyotype mapped onto B. rapa chromosome A3. The position of AK genome building blocks in chromosome A3 was defined by a comparison of B. rapa-A. thaliana syntenic relationships and the A. thaliana-AK mapping results [20, 29]. AK segments are labeled and oriented by arrows. Putative orthologs delineating the boundaries of recombination events are designated. CDs between AK blocks are indicated by dotted arrows.
