Abstract:
Insect metamorphosis has fascinated humankind throughout history, often linked to magic or supernatural powers. Now, in the 21st century, most of these old believes have been replaced by scientific knowledge, but yet, we are far from understanding the molecular basis of how one genome, produces radically different phenotypes, and how such a complex process emerged and evolved.
Insects represent more than the 90% of the living animal species, and 80% of them undergo the complete (aka. holometabolous) metamorphosis, characterized by juvenile stages dramatically different from the adult one. Thus, the origin of the holometabolous metamorphosis has been linked to the huge radiation of insects and the emergence of new morphologies and lifestyles, which allowed them to colonize virtually all terrestrial ecosystems. This holometabolous metamorphosis, emerged from the ancestral and incomplete (aka. hemimetabolous) metamorphosis in which juvenile stages are very similar to the adult one.
Through large-scale analysis of “omics” data, we have unveiled different elements of the gene regulatory network that control both types of insect metamorphosis. In this talk, I will explain our progress on the understanding of molecular regulation and evolution of insect metamorphosis through the comparison of gene expression regulatory networks, and discuss our recent findings regarding the role of the transcription factor E93.radiation of angiosperms, and provides new insights into the origin and evolution of plant diversity, the coupling of plant evolution with the evolution of the Earth’s atmospheric environment, and the ways in which plants have adapted to and shaped the Earth’s ecosystems.
