Genetic Diversity Of The Beetle, Paederus Fuscipes Curtis (Coleoptera: Staphylinidae) And Its Symbiotic Diversity With Pederin Polymorphism Based On 16S Rrna Metagenomics Profiling

Paederus rove beetles are known to carry the pederin toxin that causes linear dermatitis when crushed on skin. The toxin is produced by an unculturable Pseudomonas sp. harboured by the female Paederus beetles. Pederin polymorphism has been observed several Paederus and Paederidus beetle species wher...
