Genomic insights into clonal diversity in UK populations of the potato aphid, Macrosiphum euphorbiae.

ABSTRACT: The potato aphid Macrosiphum euphorbiae is one of many polyphagous crop pests involved in the transmission of insect-vectored pathogens. While their North American counterparts reproduce via cyclical parthenogenesis, UK populations of M. euphorbiae appear to persist asexually, resulting in the maintenance of several genotypes, with some demonstrating genotype-specific traits; this includes innate resistance to parasitism from the hymenopterous parasitoid wasp Aphidius ervi. The genetic and molecular basis for genotype-specific traits is often unknown. Here we present a chromosome scale assembly for a parasitoid-resistant clonal line of M. euphorbiae and provide insights into the genotypic composition and distribution of UK potato aphid populations using microsatellite and whole-genome sequ
