Highly Contiguous Genome Assembly of Drosophila prolongata - a Model for Evolution of Sexual Dimorphism and Male-specific Innovations.

ABSTRACT: Drosophila prolongata is a member of the melanogaster species group and rhopaloa subgroup native to the subtropical highlands of southeast Asia. This species exhibits an array of recently evolved male-specific morphological, physiological, and behavioral traits that distinguish it from its closest relatives, making it an attractive model for studying the evolution of sexual dimorphism and testing theories of sexual selection. The lack of genomic resources has impeded the dissection of the molecular basis of sex-specific development and behavior in this species. To address this, we assembled the genome of D. prolongata using long-read sequencing and Hi-C scaffolding, resulting in a highly complete and contiguous (scaffold N50 2.2Mb) genome assembly of 220Mb.
