Research Topic 1: Establishment of new species for the study of Evo-Devo in Brazil

Most studies of developmental biology and genetics in insects have been performed in the fruit fly Drosophila melanogaster (Diptera). In the past years we have established alternative model systems in the laboratory such as the kissing bug Rhodnius prolixus, the tick Rhipicephalus microplus and the mosquito Aedes aegypti to study the interplay between development, morphogenesis and gene function using a comparative approach.

Research Topic 2: Maternal-zygotic transition and axis formation

During the early stages of development messenger RNAs from the mother are replaced by those from the zygote via a global zygotic genome activation (ZGA). This initial process comprises the phenomenon of maternal-zygotic transition (MZT) and precedes axes establishment (anteroposterior and dorsoventral) and germ layers are also established.
