Fig. 2From: Genome-wide identification and expression analysis of the ftsH protein family and its response to abiotic stress in Nicotiana tabacum LPhylogenetic relationships, gene structure analysis, and motif distributions of Nicotiana tabacum L. ftsH. ftsH: filamentous temperature-sensitive H. A Phylogenetic tree constructed by the neighbour-joining method, with 1000 replicates on each node. B Exons and introns are indicated by yellow rectangles, and black lines, respectively. C Conserved domain of ftsH gene. D Amino acid motifs in the ftsH proteins (1–10) are represented by coloured boxes. Black lines indicate relative protein lengthsBack to article page
