Annotation of the Ya gene family in the M. persicae genome. (A) Level of conservation (consensus) among aligned nucleotide sequences of mature transcripts of 30 Ya genes (alignment shown in SI Appendix, Fig. S8). The small ORF may translate into a 38-aa peptide. (B) Phylogeny based on the alignment of 30 Ya transcripts shown in A. (C) Locations of Ya gene repeats on M. persicae genomic scaffolds. Ya genes are shown as arrows in colors matching those of the groups of the Ya phylogenetic tree shown in B. (D) Number of Ya genes in six aphid genomes. The tree is a maximum likelihood phylogeny based on a concatenated alignment of protein sequences of 5,111 genes.
