What is it about?
The oocytes of oviparous animals are highly specialized cells committed to the storage of nutrients (yolk) required for the maternally detached embryo development. In this work, we found that the gene components of two PI3K complexes, VPS38 and ATG14, are co-transcriptionally regulated and that they are essential for the correct accumulation of yolk in the oocytes. Without those genes, the insects are not able to produce yolk-full eggs rendering the next generation of embryos unviable.

Why is it important?
This is important because understanding the genetic basis of oocyte formation provides information that can be used to develop and test new biotechnology solutions to achieve vector population control in endemic areas.
