Evolutionary insights into the aphid genome: aphid genomics between quality problems and intriguing perspectives

In the last decade the genomes of several aphid species have been sequenced allow- ing a better understanding of their biology and evolution. Unfortunately, as frequently occurs with the next generation sequencing technologies, several aphid genomes con- sist in fragmented assemblies that contain thousands of genomic scaffolds of reduced length. In order to improve the quality of the published genomic data, several research groups are currently resequencing aphid DNA making possible to take the full advan- tage of genomics to face complex biological problems, such as aphid diversification. This review is aimed to discuss the current state of art in aphid genomics focusing in particular on the aspects that could improve our knowledge of their evolution.
