Fig. 6From: De novo assembly and annotation of Popillia japonica’s genome with initial clues to its potential as an invasive pestOR gene counts (excluding splicing variants) in the genome of P. japonica as well as A. glabripennis, L. decemlineata and T. castaneum. Subfamilies were defined following the phylogenetic reconstruction of ORs (Fig. 5). Group 2B, 3 and 4 show a strong expansion in P. japonica’s genome (from 1.2x to 21x) in comparison to other species. Instead, Group 1 and 5A apparently experienced a gene contraction in JB genome. Species are color-codedBack to article page
