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

a

The 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).

b

The obtained sequences were compared with that of AtFLC to define the regions of each BnFLC gene that were isolated.

c

To calculate sequence identities, indels (insertions or deletions) were excluded and for partial sequences of BnFLC.C2 and BnFLC.C3a, the available region was used.

d

The letter and numeral in parentheses represent the linkage group followed by the ancestral block in which the FLC homologues are located.

e

The number of nonsynonymous nucleotide substitutions is shown in parentheses.

f

There was a fragment with higher-order structure in intron 1 of BnFLC.A3a for which we failed to obtain the sequence.
