The genome of the endosymbiont-harboring trypanosomatid Kentomonas sorsogonicus

The trypanosomatid subfamily Strigomonadinae, composed of the genera Angomonas, Strigomonas, and Kentomonas, is distinguished by the obligatory presence of endosymbiotic betaproteobacteria Candidatus Kinetoplastibacterium spp.This ancient and well-established symbiotic relationship features an intensive metabolic exchange and coordination of the cell division of the participants.In contrast to the extensively studied genera Angomonas and Strigomonas, little is known about Kentomonas, which has been described in 2014.Only one genome sequence of the bacterial endosymbiont (Ca.Ki. sorsogonicusi) is available.In this work, we report the high-quality genome sequence for the trypanosomatid Kentomonas sorsogonicus, obtained by a hybrid assembly of short Illumina and long PacBio read data.The assembly has a total length of ~34.8 Mb, with many scaffolds being as long as complete chromosomes in other trypanosomatid species.Our preliminary analysis demonstrates that the genome of this trypanosomatid is quite divergent, which significantly hampers functional annotation of its genes.
