Sequence alignment and logo view of variable SBP domains, and putative motifs of variable SPLs in group III. (a) Multiple alignment of the SBP domains using DNAMAN software. The four conserved motifs, which include two zinc finger-like structures (C4H, C2HC), Jp and NLS, are indicated; (b) Sequence logo view of the consensus SBP domains. The overall height of the stack and the height of each letter represent the sequence conservation at that position and the relative frequency of the corresponding amino acid at that position, respectively; (c) putative motifs of variable SPLs in group III identified by MEME software online (http://meme-suite.org/tools/meme). The color boxes represent different putative motifs for which the sequences are listed in Table S2 online. G-III indicates group III from Figure 1.
