Figure 4From: Conserved microstructure of the Brassica B Genome of Brassica nigra in relation to homologous regions of Arabidopsis thaliana, B. rapa and B. oleraceaPhylogenetic tree of the Brassica B and A/C lineage. The percentage of fractionation for the three sub-genomes at each node is specified. The contigs are ordered according to the overall level of fractionation from least (LF) to most fractionated (MF2) (Table 3).Back to article page
