Despite the devastating impact of mosquito-borne illnesses on human health , surprisingly little is known about mosquito developmental biology , including development of the olfactory system , a tissue of vector importance . Analysis of mosquito olfactory developmental genetics has been hindered by a lack of means to t... | Although mosquitoes transmit many of the world's deadliest diseases , mosquito developmental biology has been grossly understudied . To address this issue , we have begun to develop the dengue and yellow fever vector Aedes aegypti as an emerging model for understanding mosquito developmental genetics . In this investig... | [

The gene composition of present-day genomes has been shaped by a complicated evolutionary history , resulting in diverse distributions of genes across genomes . The pattern of presence and absence of a gene in different genomes is called its phylogenetic profile . It has been shown that proteins whose encoding genes ha... | Every genome of current day species contains a very unique selection of genes . Why a specific genome is composed of exactly those genes is determined by many factors , but often not resolvable . It seems plausible that interacting genes would either occur together or be absent together , because if one of them is alon... | [
