摘要: Abstract The foxglove aphid (or glasshouse potato aphid, Aulacorthum solani Kaltenbach) transmits serious viruses (potato virus Y, and leaf roll virus) which cause heavy yield losses. Our aim of this study was to preliminary analysis draft genome sequence uncover virulence genes in the aphid. assembly size (316.39 Mb) very close its (318.19 estimated by flow cytometry. completeness (81.8 %) confirmed Benchmarking Universal Single Copy Orthologs (BUSCO) indicating 14.90 % transposable elements (TEs) genome. Of total 22021 predicted genes, 16610 were annotated with putative functions other aphids mainly Myzus persicae, Acyrthosiphon pisum Diuraphis noxia. We identified such as defensive detoxification salivary chemoreceptors, insecticide resistance transmission transcription factors mitochondrial genes. Importantly, particularly 53 cytochrome P450s (CYPs) indicated involvement 23 CYPs families Further, GO KEGG pathways analyses showed gene enrichment predominantly molecular function signal transduction, respectively. Phylogeny revealed genetic divergence among 12 species Au. is closely related M. persicae. non-synonymous (Ka)/synonymous (Ks) substitutions (Ka/Ks) positive selection for 6 (Ka/Ks > 1) 122 = 0.5 single copy orthologous pairs between pea Thus, our provides new insights understand basis biology, host-aphid interactions adaptation mechanism.
