Schematic representation of molecular phylogenetic relationships and gene structure of WAK/WAKLs in Nicotiana benthamiana. The phylogenetic tree was constructed using the Maximum-likelihood method with 1000 bootstrap replicates for each branch through MEGA 11.0. The diagrammatic genomic organization of NbWAK/WAKLs was produced using the Gene Structure Display Server (GSDS) 2.0. Upstream sequences, exons, introns, and downstream sequences are indicated by green boxes, yellow boxes, black lines, and blue boxes, respectively
