Abstract

Wolbachia are endosymbiotic bacteria of arthropods and nematodes that can manipulate the reproduction of various host organisms to facilitate their own maternal transmission. Moreover, Wolbachia’s presence in host germ cells may contribute to the many cases of lateral gene transfer from Wolbachia to host genomes that have been described. A previous study in Chorthippus parallelus, a well-known orthopteroid forming a hybrid zone in the Pyrenees, identified Wolbachia sequences from two major supergroups in the genomes of infected and uninfected Chorthippus parallelus parallelus (Cpp) and Chorthippus parallelus erythropus (Cpe) subspecies. In this study, we map the Wolbachia genomic inserts to specific regions on the chromosomes of Cpp and Cpe by fluorescent in situ hybridization (FISH) using tyramides to increase the accuracy and detection of these insertions. Additionally, we consider some of the possible roles that these bacterial inserts play in the organization and function of the grasshopper genome, as well as how they can serve as markers for phylogenetic relationships of these organisms.
