Novel Genome Sequences and Evolutionary Dynamics of the North American Anopheline Species Anopheles freeborni, crucians, quadrimaculatus, and albimanus
Anopheles mosquitoes are the principal vectors for malaria and lymphatic filariasis, and evidence for arboviral transmission under laboratory and natural contexts has been demonstrated. Vector management approaches require an understanding of the ecological, epidemiological, and biological context of the species in question, and increased interest in gene drive systems for vector control applications has resulted in an increased need for genome assemblies from understudied mosquito vector species. In this study we present novel genome assemblies for An. crucians, An. freeborni, An. albimanus, and An. quadrimaculatus and examine the evolutionary relationship between these species. We identified 790 shared single copy orthologs between the newly sequenced genomes and created a phylogeny using 673 of the orthologs, identifying 525 orthologs with evidence for positive selection on at least one branch of the phylogeny. Gene ontology terms such as calcium ion signaling, histone binding, and protein acetylation identified as being biased in the set of selected genes. These novel genome sequences will be useful in developing our understanding of the diverse biological traits that drive vectorial capacity in anophelines.
