Dipylidium caninum draft genome - a new resource for comparative genomic and genetic explorations of flatworms

Highlights

• We present a draft genome of the tapeworm Dipylidium caninum.

• We investigated the genetic relationships of cestodes for which nuclear genomes are available.

• This study provides first insights into the molecular genetics and biology of D. caninum.

Abstract

Here, we present a draft genome of the tapeworm Dipylidium caninum (family Dipylidiidae) and compare it with other cestode genomes. This draft genome of D. caninum is 110 Mb in size, has a repeat content of ~13.4% and is predicted to encode ~10,000 protein-coding genes. We inferred excretory/secretory molecules (representing the secretome), other key groups of proteins (including peptidases, kinases, phosphatases, GTPases, receptors, transporters and ion-channels) and predicted potential intervention targets for future evaluation. Using 144 shared single-copy orthologous sequences, we investigated the genetic relationships of cestodes for which nuclear genomes are available. This study provides first insights into the molecular biology of D. caninum and a new resource for comparative genomic and genetic explorations of this and other flatworms.
