Phylogenetic relationships, gene structure and conserved motif compositions of the NF-Y family in B. napus and Arabidopsis. (a) The phylogenetic relationships of the BnaNF-Y and AtNF-Y genes. The 108 genes of B. napus and 36 genes of Arabidopsis are divided into three groups; (b) Conserved motif compositions. Each colored box in the middle represents a motif, and the black line represents non-conserved sequences; (c) Gene structure. The untranslated region (UTR), exon and intron in the right of each subfamily are represented by a green box, yellow box and gray line, respectively.
