Acyrthosiphon pisum (Aphididae, Macrosiphini) is an economically important parasite of legume crops (Fabaceae) and is considered the model species of aphid. Like all Aphididae it forms a symbiotic obligate relationship with Buchnera aphidicola and in 2010 they became the first insect-endosymbiont pair to have the genomes of both partners sequenced. A. pisum was also the first basal hemimetabolous with a sequenced genome.
A 464 Mb draft genome assembly of A. pisum was prepared by the International Aphid Genomics Consortium. Analysis of the genome suggests that co-evolution with Buchnera may have led to extensive gene loss including genes involved in immunity related pathways, selenoprotein utilisation, purine salvage and the entire urea cycle. In contrast 2000 gene families in A. pisum are duplicated, including those involved in miRNA synthesis and sugar transport.
