Draft genomes of two blister beetles Hycleus cichorii and Hycleus phaleratus

Wu, Y; Li, J; Chen, X (2018): Draft genomes of two blister beetles Hycleus cichorii and Hycleus phaleratus GigaScience Database. http://dx.doi.org/10.5524/100405 RIS BibTeX Text

Commonly known as blister beetles or Spanish fly, there are more than 1,500 species in the Meloidae family (Hexapoda:Coleoptera:Tenebrionoidea) that produce the potent defensive blistering agent cantharidin. Cantharidin and its derivatives have been used to treat cancers, such as liver, stomach, lung and esophageal cancers. Hycleus cichorii and Hycleus phaleratus are the most commercially important blister beetles due to their ability to biosynthesize this potent vesicant. However, there is a lack of genome reference, which has hindered development of studies on the biosynthesis of cantharidin and a better understanding of its biology and pharmacology. We report two draft genomes and quantified gene sets for blister beetles H. cichorii and H. phaleratus, two complex genomes with >72 % repeats and ~1 % heterozygosity, using Illumina sequencing data. An integrated assembly pipeline was performed for assembly and most of the coding regions were obtained. BUSCO assessment showed that our assembly obtained more than 98 % of the Endopterygota universal single-copy orthologs. Comparison analysis showed that the completeness of coding gene in our assembly was comparable to other beetle genomes such as Dendroctonus ponderosae and Agrilus planipennis. Gene annotation yielded 13,813 and 13,725 protein-coding genes in H. cichorii and H. phaleratus, of which ~89 % were functionally annotated. BUSCO assessment showed that ~86 and 84 % of the Endopterygota universal single-copy orthologs were annotated completely in these two gene sets, whose completeness is comparable to that of D. ponderosae and A. planipennis. Assembly of the both blister beetle genomes provide a valuable resource for future biosynthesis of cantharidin and comparative genomic studies of blister beetles and other beetles.
