Title The draft genome of the specialist flea beetle Altica viridicyanea (Coleoptera: Chrysomelidae) provides insight into host plant specialization

Organisms Altica viridicyanea
Description Altica (Coleoptera: Chrysomelidae) is a highly diverse and taxonomically challenging flea beetle genus that has been used as a model system in which to address questions related to host plant specialization, reproductive isolation, and ecological speciation. To further evolutionary studies in this important group, here we present a high-quality draft genome of a representative specialist, Altica viridicyanea, the first Alticinae genome and the third chrysomelid genome reported thus far. The genome is 864.8 Mb and consists of 4,490 scaffolds with a N50 size of 557 kb, which covered 95.8% complete and 2.1% partial Endopterygota Benchmarking Universal Single-Copy Orthologs. Repetitive sequences accounted for 62.9% of the assembly, and a total of 17,730 protein-coding gene models and 2,462 non-coding RNA models were predicted. To provide insight into host plant specialization of this monophagous species, we examined the key gene families involved in chemosensation, detoxification of plant secondary chemistry, and plant cell wall-degradation. The high-quality genome assembled in this work provides an important resource for further studies on host plant adaptation and functionally affiliated genes. Moreover, this work also opens the way for comparative genomics studies among closely related Altica species, which may provide insights into the molecular evolutionary processes that occur during ecological speciation.
