Phylogenetic relationships, exon-intron structure, and motif compositions of <i>FvNAC</i> genes.

<p>(a) The unrooted phylogenetic tree was constructed using full-length protein sequences of 37 <i>FvNAC</i> genes by the neighbor-joining method using 1000 bootstrap replicates. (b) Exon-intron structure analyses of <i>FvNAC</i> genes were performed by using the online tool GSDS 2.0. Lengths of exons and introns of each FvNAC genes were exhibited proportionally. (c) The motif composition related to each FvNAC protein. The motifs numbered 1–17 are displayed in different colored boxes. The sequence information for each motif is provided in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0197892#pone.0197892.s015" target="_blank">S1 Fig</a>.
