Wolbachia is a maternally transmitted bacterium that is widespread in arthropods and filarial nematodes and confers strong antiviral protection in Drosophila melanogaster and other arthropods. Wolbachia-transinfected Aedes aegypti mosquitoes are currently being deployed to fight transmission of dengue and Zika viruses. However, the mechanism of ant...
Wolbachia, endosymbionts that reside naturally in up to 40-70% of all insect species, are some of the most prevalent intracellular bacteria. Both Wolbachia wAu, naturally associated with Drosophila simulans, and wMel, native to Drosophila melanogaster, have been previously described to protect their hosts against viral infections. wMel transferred...
Wolbachia are intracellular bacterial symbionts that are able to protect various insect hosts from viral infections. This tripartite interaction was initially described in Drosophila melanogaster carrying wMel, its natural Wolbachia strain. wMel has been shown to be genetically polymorphic and there has been a recent change in variant frequencies i...
Alignments and phylogenetic trees of insect Antp, Hh and Ptc proteins. (A) Schematic representation of the phylogenetic relationship between insect species (adapted from the Tree of Life [68]) for which protein sequences are compared with those encoded by the B. anynana genes cloned in this study. Multiple sequence alignment of the predicted B. any...
Early gene expression in Bicyclus anynana larval wing discs. Forewings of one single individual at early last instar stage, prior to extension of trachea into the vein lacunae. Right wing disc stained for detection of Antp protein, and left wing disc for N and Dll proteins (see Material and methods). The right wing disc is also shown in bright fiel...
Hox proteins specify segment identity during embryogenesis and have typical associated expression patterns. Changes in embryonic expression and activity of Hox genes were crucial in the evolution of animal body plans, but their role in the post-embryonic development of lineage-specific traits remains largely unexplored. Here, we focus on the insect...
All authors with their affiliations appear at the end of this paper This paper is dedicated to future Tropical Biology Association (TBA) students, who we hope will expand and refine the Kirindy pollination web. Abstract—Tropical dry deciduous forest is an endangered ecosystem whose plant-pollinator relationships are little known. We characterised a...
