Brassica napus FLC homologues, their map positions, and sequence identities compared with their orthologues in B. rapa or B. oleracea.

aThe sequences isolated from BACs are indicated by an asterisk, and those isolated from PCR-amplified genomic DNA are designated ‘gDNA’ with the parent indicated in parentheses (T, B. napus cv. Tapidor; N, B. napus cv. Ningyou7).bThe obtained sequences were compared with that of AtFLC to define the regions of each BnFLC gene that were isolated.cTo calculate sequence identities, indels (insertions or deletions) were excluded and for partial sequences of BnFLC.C2 and BnFLC.C3a, the available region was used.dThe letter and numeral in parentheses represent the linkage group followed by the ancestral block in which the FLC homologues are located.eThe number of nonsynonymous nucleotide substitutions is shown in parentheses.fThere was a fragment with higher-order structure in intron 1 of BnFLC.A3a for which we failed to obtain the sequence.
