Transcriptomic analysis confirms differences among nuclear genomes of cryptic earthworm lineages living in sympatry.

ABSTRACT: BACKGROUND:Many earthworm species demonstrate significant cryptic diversity, with several highly diverged mitochondrial lineages found within most of the taxa studied to date. The status of differences between these lineages on the nuclear level is still unclear. Because of widespread polyploidy in earthworms, most studies were limited to two nuclear loci, the ribosomal and the histone clusters. Here we attempted to elucidate the status of a set of genetic lineages within Eisenia nordenskioldi nordenskioldi, an earthworm species from Northern Asia with high intraspecific diversity. We performed RNA-seq on an IonTorrent platform for five specimens of this species belonging to five genetic lineages, as well as two outgroups from the family Lumbricidae, the congenetic E. andrei, and Lumbricus
