Heritable symbionts are usually specialized and isolated from other bacteria with little known about the origins of...

Diet-Microbiota Interactions Alter Mosquito Development

Gut microbes and diet can both strongly affect the biology of multicellular animals, but it is often difficult to disentangle microbiota-diet interactions due to the complex microbial communities many animals harbor and the nutritionally variable diets they consume. While theoretical and empirical studies indicate that...

However, while mammalian TLRs directly recognize pathogen-associated molecular patterns, the insect Toll pathway is thought to be primarily activated by binding...

Riboflavin instability is a key factor underlying the requirement of a gut microbiota for mosquito development

We previously determined that several diets used to rear Aedes aegypti and other mosquito species support the development of larvae with a gut microbiota but do not support the development of axenic larvae. In contrast, axenic larvae have been shown to develop when fed other diets. To...

Prior studies show that the number of eggs females lay per clutch correlates with the volume of blood ingested and that...

MdBVe46 is an envelope protein that is required for virion formation by Microplitis demolitor bracovirus

Bracoviruses (BVs) are endogenized nudiviruses that braconid parasitoid wasps have coopted for functions in parasitizing hosts. Microplitis demolitor is a braconid wasp that produces Microplitis demolitor bracovirus (MdBV) and parasitizes the larval stage of the moth Chrysodeixis includens. Some BV core genes are homologs of genes also present...

Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes...

Results We sequenced the genomes...
