Comparative genome organization of the A genome of B. juncea (A1–A10; present study) and B. napus (N1–N10) [16]. This file contains the map of the A genome of B. napus [16] with the RFLP loci converted to their corresponding At (A. thaliana) loci and a detailed comparison (in terms of the At loci arrangement) of this map with the A genome of B. juncea (present study).

Comparative genome organization of the B genome of B. juncea (B1–B8; present study) and B. nigra (G1–G8) [18]. This file contains the map of the B genome of B. nigra [18] with the RFLP loci converted to their corresponding At (A. thaliana) loci and a detailed comparison (in terms of the At loci arrangement) of this map with the B genome of B. juncea (present study).

Putative ancestral Brassica karyotype (ABK2–ABK6). The file contains the figurative representation of the putative ancestral Brassica karyotype (ABK2–ABK6) predicted in our study. This is based on the conserved group structure of groups 2, 3, 4, 5 and 6 (Figure 7). Only partial organization of the putative linkage groups ABK2 and ABK3 is shown representing the common blocks shared between the three diploid Brassica genomes.
