Project description:Heteromorphic sex chromosomes induce potentially deleterious gene expression imbalances that are frequently corrected by dosage compensation (DC). Three distinct molecular strategies to achieve DC have been previously described in nematodes, fruit flies and mammals. The reason for these mechanistic differences remain unclear: Are they a consequence of distinct genomes and gene content, functional or ecological constraints, or random initial commitment to an evolutionary trajectory? Here, we study DC in the malaria mosquito Anopheles gambiae. The X chromosomes of Anopheles and Drosophila evolved independently, yet from the same ancestral autosome and share a high degree of homology. We find that Anopheles achieves DC by an entirely different mechanism compared to the MSL complex - H4K16ac axis operating in Drosophila. CRISPR knock-out of msl-2 in Anopheles leads to early embryonic lethality and affects both sexes. Transcriptome analyses indicate that this phenotype is not a consequence of defective X chromosome DC, but instead relates to misregulation of developmental genes. Furthermore, Histone H4 Lysine 16 acetylation does not mark an X chromosome territory, neither does it display a sexually dimorphic genome-wide distribution by ChIP. We conclude that a novel pathway confers X chromosome upregulation in male Anopheles. Our findings highlight the pluralism of how organisms cope with gene-dosage alterations and show that different mechanisms can evolve even in scenarios of highly similar genomic and functional constraints.

Project description:Chromosomal inversions play a fundamental role in evolution and have been shown to be responsible for the epidemiologically important traits in malaria mosquitoes. However, they have never been characterized in the major vector of arboviruses Aedes aegypti because of the poor structure of its polytene chromosomes. In this study, we applied a Hi-C proximity ligation approach to identify chromosomal inversions in 23 recently collected strains of Ae. aegypti from its worldwide distribution, two old laboratory colonies, and Ae. mascarensis.

Project description:Wolbachia, an endosymbiotic bacterium, is being investigated as a vector control agent in several insect species. Along with the well known classical reproductive parasitism Wolbachia employs against its host to spread within the population, it is emerging that the bacteria can protect the host against pathogens and reduced pathogen transmission. Anopheles mosquitoes, which transmit malaria, have never been found to harbour Wolbachia in nature, and despite numerous transinfection attempts, no stable line has been developed. However recently, two strains of Wolbachia, wAlbB from Aedes albopictus, and wRi from Drosophila simulans were cultured in Anopheles gambiae Sua5B cells. These cell lines provides an amenable system to study Wolbachia-Anopheles interaction in the absence of a stable transinfected line. It has been proposed that the compromised vector competence of Wolbachia infected insects is due to an up regulation of the basal immune state. We therefore completed a genome wide expression profile of Wolbachia infected Anopheles, assessing both wAlbB and wRi infected cells in parallel against uninfected Sua5B cells.
