Phylogenetic analysis of WAK and WAKL amino acid sequences from tomato, Arabidopsis and Nicotiana benthamiana. Green font and lines indicate Arabidopsis proteins. Black and red lines indicate N. benthamiana and tomato, respectively. The light gray accession numbers for tomato and N. benthamiana are proteins for whose genes few or no RPKM were detected. For all comparisons a ≥2-fold difference and P < 0.05 were used as cut-offs. RPKM, reads per kilobase of exon model per million mapped reads.
