Phylogenetic relationships, architecture of conserved protein motifs and gene structure of the SnRK genes from B.napus. a Phylogenetic tree of 104 BnSnRK proteins. The unrooted neighbor-joining phylogenetic tree was constructed with MEGA7 using full-length amino acid sequences of 104 BnSnRK proteins, and the bootstrap test replicate was set as 1000 times. b Exon/intron organization of BnSnRK genes. Yellow boxes represent exons and black lines with same length represent introns. The upstream/downstream region of BnSnRK genes are indicated in green boxes. The length of exons can be inferred by the scale at the bottom. c The motif composition of BnSnRK proteins. The motifs, numbers 1–10, are displayed in different colored boxes. The sequence information for each motif is provided in Table S4. The length of protein can be estimated using the scale at the bottom
