About Heterorhabditis bacteriophora
The nematode Heterorhabditis bacteriophora, species of Rhabditoidea, was originally recovered from Heliothis punctigera Hall (Noctuidae) at Brecon, South Australia. The infective stage juveniles of this nematode carry a specific bacterium in their intestines which is released after the parasites enter the body cavity of a healthy insect. The bacteria kill the insect in 48 hours, and the infective stage juveniles develop into hermaphroditic females that produce young which develop into males and females. The latter mate and produce juveniles that develop into infective stages, which leave the cadaver and search for a new host. H. bacteriophora differs from other nematodes in the Rhabditoidea by possessing a vestigial valve in the basal pharyngeal bulb, a reduced stoma, and dauer stages capable of entering the body cavity of healthy insects. Aside from members of the genus, Neoaplectana, it is the only nematode known to serve as a vector for a bacterial disease of insects. The new species also exhibits heterogony.
Genome Assembly & Annotation
Assembly
The H. bacteriophora genome has been sequenced by Ohio State University and the Genome Institute at Washington University, as described by Bai et al (2013). The assembly version represented here is that submitted directly to WormBase, which is practically the same as NCBI assembly GCA_000223415.1 but contains a 23 additional scaffold that were not accepted by INSDC.
Annotation
The gene predictions were made by Ohio State University, as described by Bai et al (2013). The version represented here is that submitted directly to WormBase in 2013.
