Figure 1.

Multiple sequence alignment of peptides of kiwifruit PGs containing the four conserved domains. The underlines indicate the four typical conserved domains of PGs, referred to as domain I, II, III and IV as previously reported (Qian et al., 2016). Different shading colors illustrate different similarities (red: 100%, blue: ≥80%, green: ≥60%). The consensus sequence is shown at the bottom by letter logos. The bit score indicates the relative frequency of each amino acid at that position.
