Motif analysis of odorant binding proteins (OBPs) and chemosensory proteins (CSPs) from five aphid species. The parameters used for motif discovery were minimum width = 6, maximum width = 10 and maximum number of motifs to find = 8. The upper parts in (A) and (B) list the eight motifs discovered in the five aphids’ OBPs and CSPs, respectively. All the motifs were discovered using meme (version 4.11.4; Bailey et al., 2009) online server (https://meme-suite.org/). The lower parts indicate approximate locations of each motif on the protein sequence. The numbers in the boxes correspond to the numbered motifs in the upper part of the figure, where small numbers indicate high conservation. The numbers on the bottom show the approximate locations of each motif on the protein sequence, starting from the N‐terminus. (A) The eight most common motif patterns which presented in 38 OBPs, with each motif pattern present in more than three OBPs; the remaining seven OBPs had five different motif patterns, with each of them presented in less than four OBPs. (B) All five motif patterns which presented in 41 CSPs, and each motif pattern presented in more than three CSPs. The protein names and sequences of the 45 OBPs and 41 CSPs from five different aphid species are listed in Supporting Information Table S2. [Colour figure can be viewed at wileyonlinelibrary.com]
