Two florigen genes BrFT1 and BrFT2 were analyzed from the genome of Chinese cabbage(Brassica rapa subsp.pekinensis) by the comparative genomics method,and their structure,cis-acting elements and phylogeny were investigated.The results showed that the genomic sequence of the two genes both contained 4 exons,and the coding region was 528 bp.The sequence identity of the predicted proteins encoded by them was 90.29%,which suggested they should be functionally conserved.Phylogeny analysis indicated that BrFT1 an...
