Genome-wide identification and expression profiling of the carotenoid cleavage dioxygenase (CCD) gene family in Brassica napus L
Fig 3
Exon–intron structures of the BnCCD genes, arranged based on their phylogenetic relationships.
An unrooted phylogenetic tree was constructed based on the full-length sequences of BnCCD proteins using the N-J method in MEGA7. Bootstrap values based on 1,000 replications were calculated. The exon–intron structure of the BnCCD genes was analyzed using the GSDS online tool. The lengths of the exons and introns for each BnCCD gene are drawn to scale.
