The research carried out by this lab aims at understanding the mechanisms that regulate insect oogenesis. The model used is Blattella germanica, an insect with a panoistic ovary type, which is the most primitive ovary type among insects. This lab studies the expression of the genes involved in the main signalling pathways and its regulation by hormones and by the small non-coding RNA that modulates them. The comparison of these results with those already described in other, more modified insect species, suggests that some functions are preserved in evolution, although the regulation of these functions could have changed.
