Long-read-based Genome Assembly of Drosophila gunungcola Reveals Fewer Chemosensory Genes in Flower-breeding Species.

ABSTRACT: Drosophila gunungcola exhibits reproductive activities on the fresh flowers of several plant species and is an emerging model to study the co-option of morphological and behavioral traits in male courtship display. Here, we report a near-chromosome-level genome assembly that was constructed based on long-read PacBio sequencing data (with ∼66× coverage) and annotated with the assistant from RNA-seq transcriptome data of whole organisms at various developmental stages. A nuclear genome of 189 Mb with 13,950 protein-coding genes and a mitogenome of 17.5 kb were acquired. Few interchromosomal rearrangements were found in the comparisons of synteny with Drosophila elegans, its sister species, and Drosophila melanogaster, suggesting that the gene compositions on each Muller element are evolution
