“…A comparison of the B. rapa genome sequence with previously reported linkage maps shows that block D on chromosome A01; blocks W, Q, X, M, and D on A03; S on A05; M, H, and U on A6; F, X, and S on A07; S on A08; K, L, and M on A09; and C on A10 were not detected by genetic mapping (Parkin et al, 2005;Panjabi et al, 2008;Kim et al, 2009;Trick et al, 2009). Although the assembly of B. rapa chromosome A03 by Mun et al (2010) identified 14 GBs or block segments, three additional blocks on the same chromosome were detected within the B. rapa reference genome . Similarly, the 2.4-Mb fragment of block W within the V/K/L/Wa/Q/X association was not detected by genetic mapping.…”
