A Horizontally Transferred Autonomous Helitron Became a Full Polydnavirus Segment in Cotesia vestalis
Bracoviruses associate symbiotically with thousands of parasitoid wasp species in the family Braconidae, working as virulence gene vectors, and allowing the development of wasp larvae within hosts. These viruses are composed of multiple DNA circles that are packaged into infective particles, and injected together with wasp's eggs during parasitization. One of the viral segments of Cotesia vesta...
متن کاملCharacterization of two genes of Cotesia vestalis polydnavirus and their expression patterns in the host Plutella xylostella.
Cotesia vestalis is an endoparasitoid of larval stages of Plutella xylostella, the diamondback moth. For successful parasitization, this parasitoid injects a polydnavirus into its host during oviposition. Here we isolated two genes, which we named CvBV1 and CvBV2. CvBV1 was located on segment CvBV-S5 with a size of 790 bp, while CvBV2 was located on segment CvBV-S51 with a size of 459 bp. A gen...
متن کاملCotesia vestalis teratocytes express a diversity of genes and exhibit novel immune functions in parasitism
Some endoparasitoid wasps lay eggs that produce cells called teratocytes. In this study, we sequenced and analyzed the transcriptome of teratocytes from the solitary endoparasitoid Cotesia vestalis (Braconidae), which parasitizes larval stage Plutella xylostella (Plutellidae). Results identified many teratocyte transcripts with potential functions in affecting host immune defenses, growth or me...
متن کاملTranscriptome Pyrosequencing of the Parasitoid Wasp Cotesia vestalis: Genes Involved in the Antennal Odorant-Sensory System
Cotesia vestalis is an endoparasitic wasp that attacks larvae of the diamondback moth (Plutella xylostella), a herbivore of cruciferous plants. Females of C. vestalis use herbivore-induced plant odorants released from plants infested by P. xylostella as a host-searching cue. Transcriptome pyrosequencing was used to identify genes in the antennae of C. vestalis adult females coding for odorant r...
متن کاملExperimental support for multiple-locus complementary sex determination in the parasitoid Cotesia vestalis.
Despite its fundamental role in development, sex determination is highly diverse among animals. Approximately 20% of all animals are haplodiploid, with haploid males and diploid females. Haplodiploid species exhibit diverse but poorly understood mechanisms of sex determination. Some hymenopteran insect species exhibit single-locus complementary sex determination (sl-CSD), where heterozygosity a...
