Comparative mapping of B. rapa linkage groups containing replicated FLC genes to the Arabidopsis genome. Vertical lines represent homeologous linkage groups in B. rapa, two loci of BrFLC3a and FLC3b are the polymorphic segregating RFLP genotype data using the BrFLC gene (AY273164), and the other three, BrFLC1, BrFLC2, and BrMAF, are the segregated genotype data using developed SSR markers from BACs containing FLC and MAF genes. R2, R3, and R10 show the sequenced homology to Arabidopsis chr5 (0.5–7 Mb and 20.5–26.2 Mb, respectively). Originated FLC of Arabidopsis is triplicated at the top of R10 and R2 and at the bottom of R3, and a local duplication event has happened at the bottom of R3. The BrFLC5 gene mapped region shows R4 and -5 homeologues and corresponds to Arabidopsis chr3 (0–1 Mb and 12.3–18.9 Mb, respectively).
