Genome of tropical bed bug Cimex hemipterus (Cimicidae, Hemiptera) reveals tetraspanin expanded in bed bug ancestor.
Cimex species are ectoparasites that exclusively feed on warm-blooded animals such as birds and mammals. Three cimicid species are known to be persistent pests for humans, including the tropical bed bug Cimex hemipterus, common bed bug Cimex lectularius, and Eastern bat bug Leptocimex boueti. To date, genomic information is restricted to the common bed bug C. lectularius, which limits understanding their biology and to provide controls of bed bug infestations. Here, a chromosomal-level genome assembly of C. hemipterus (495 Mb [megabase pairs]) contained on 16 pseudochromosomes (scaffold N50 = 34 Mb), together with 9 messenger RNA and small RNA transcriptomes were obtained. In comparison between hemipteran genomes, we found that the tetraspanin superfamily was expanded in the Cimex ancestor. This study provides the first genome assembly for the tropical bed bug C. hemipterus, and offers an unprecedented opportunity to address questions relating to bed bug infestations, as well as genomic evolution to hemipterans more widely.
期刊介绍：
Insect Science is an English-language journal, which publishes original research articles dealing with all fields of research in into insects and other terrestrial arthropods. Papers in any of the following fields will be considered: ecology, behavior, biogeography, physiology, biochemistry, sociobiology, phylogeny, pest management, and exotic incursions. The emphasis of the journal is on the adaptation and evolutionary biology of insects from the molecular to the ecosystem level. Reviews, mini reviews and letters to the editor, book reviews, and information about academic activities of the society are also published.
