From: Comparative mapping of Brassica juncea and Arabidopsis thaliana using Intron Polymorphism (IP) markers: homoeologous relationships, diversification and evolution of the A, B and C Brassica genomes

Figure 7

The block arrangements in the A and B genomes are based on the consensus block arrangement of the A genomes of B. juncea (A1–A10; present study) and B. napus (N1–N10) [16] and the B genomes of B. juncea (B1–B8; present study) and B. nigra (G1–G8) [18]. The C genome is based on the B. napus map (N11–N19) [16]. The original nomenclature of the 2 LGs of the C genome (N16 and N17) and all the LGs of the B genome (G1–G8) have been shown in parentheses with the re-designated nomenclature. Certain single gene insertions were considered as putative blocks (marked with asterisk) if a similar block was found present at the corresponding region in the homoeologous chromosome. Filled bars represent the common blocks shared between all the three members of the group. Large gaps (≥10 cM regions devoid of any markers) in the LGs have been depicted by hatched boxes. Arrows represent the orientation of the gene order (within the block) with respect to the corresponding regions in At.
