Abstract

The extent of the conservation of synteny and gene order in aphids has been previously investigated only by comparing a small subset of linkage groups between the pea aphid Acyrthosiphon pisum and a few other aphid species. Here we compared the localization of eight A. pisum scaffolds (covering more than 5 Mb and 83 genes) in respect to the Drosophila melanogaster Muller elements identifying orthologous loci spanning all the four A. pisum chromosomes. Comparison of the genetic maps revealed a conserved synteny across different loci suggesting that the study of the fruit fly Muller elements could favour the identification of chromosomal markers useful for the study of chromosomal rearrangements in aphids. A. pisum is the first aphid species to have its genome sequenced and the finding that there are several chromosomal regions in synteny between Diptera and Hemiptera indicates that the genomic tools developed in A. pisum will be broadly useful not only for the study of other aphids but also for other insect species.
