Characterization of FLOWERING LOCUS C 5 in Brassica rapa L.

ABSTRACT: Brassica rapa L., which includes Chinese cabbage, turnip, and pak choi, has more complex flowering time regulation than does Arabidopsis thaliana due to the presence of multiple paralogous flowering time genes. FLOWERING LOCUS C (FLC) is one of the key genes regulating the flowering time, and B. rapa has four FLC paralogs. BrFLC5 on the reference genome is deemed a pseudogene because of a mutation (from G to A) in the splice site of the third intron, but there are some accessions with a G nucleotide in the splice site. In this study, we genotyped 310 B. rapa accessions and found that 19 had homozygous and 81 had heterozygous putative functional BrFLC5 alleles. Accessions of turnip showed the highest proportion with a functional
