The draft genome of the specialist flea beetle Altica viridicyanea (Coleoptera: Chrysomelidae)

Abstract Background Altica (Coleoptera: Chrysomelidae) is a highly diverse and taxonomically challenging flea beetle genus that has been used to address questions related host plant specialization, reproductive isolation, ecological speciation. To further evolutionary studies in this interesting group, here we present draft genome of representative specialist, viridicyanea , the first Alticinae reported thus far. Results The 864.8 Mb consists 4490 scaffolds with N50 size 557 kb, which covered 98.6% complete 0.4% partial insect Benchmarking Universal Single-Copy Orthologs. Repetitive sequences accounted for 62.9% assembly, total 17,730 protein-coding gene models 2462 non-coding RNA were predicted. provide insight into specialization monophagous species, examined key families involved chemosensation, detoxification secondary chemistry, cell wall-degradation. Conclusions assembled work provides an important resource on adaptation functionally affiliated genes. Moreover, also opens way comparative genomics among closely may molecular processes occur during
