Dinocampus coccinellae isolate:C7_Kansas Genome sequencing and assembly

posted on 2024-01-27, 05:11 authored by California State University San Marcos
Dinocampus coccinellae (Hymenoptera: Braconidae) is a generalist parasitoid wasp that parasitizes >50 species of predatory lady Coccinellid beetles (Coleoptera: Coccinellidae), with thelytokous parthenogeny as its primary mode of reproduction. Here we present the first high quality genome of D. coccinellae using a combination of short and long read sequencing technologies, followed by assembly and scaffolding of chromosomal segments using Chicago+HiC technologies. We also present a first-pass ab initio genome annotation, and resolve timings of divergence and evolution of (1) solitary behavior vs eusociality, (2) arrhenotokous vs thelytokous parthenogenesis, and (3) rates of gene loss and gain among Hymenopteran lineages. Our study finds (1) at least two independent origins of eusociality and solitary behavior among Hymenoptera, (2) two independent origins of thelytokous parthenogenesis from ancestral arrhenotoky, and (3) accelerated rates of gene duplications, loss, and gain along the lineages leading to D. coccinellae. Our work both affirms the ancient divergence of Braconid wasps from ancestral Hymenopterans, and accelerated rates of evolution in response to adaptations to novel hosts, including polyDNA viral co-evolution.
