Animals and fungi have radically distinct morphologies, yet both evolved within the same
eukaryotic supergroup: Opisthokonta 1 , 2 . Here we reconstructed the trajectory of genetic …

The evolutionary path from protists to multicellular animals remains a mystery. Recent work
on the genomes of several unicellular relatives of animals has shaped our understanding of …

Genes and genomes can evolve through interchanging genetic material, this leading to
reticular evolutionary patterns. However, the importance of reticulate evolution in eukaryotes, …

Progression through the cell cycle in eukaryotes is regulated on multiple levels. The main
driver of the cell cycle progression is the periodic activity of cyclin-dependent kinase (CDK) …

The conservation of orthologs of most subunits of the origin recognition complex (ORC) has
served to propose that the whole complex is common to all eukaryotes. However, various …

Caullerya mesnili is a common and virulent parasite of the water flea, Daphnia. It was
classified within the Haplosporidia (Rhizaria) for over a century. However, a recent molecular …

The ciliate Tetrahymena thermophila does not require sterols for growth and synthesizes
pentacyclic triterpenoid alcohols, mainly tetrahymanol, as sterol surrogates. However, when …

[EN] This thesis is centred, on the one hand, on reconstructing the evolution of gene families
that are potentially related to specific cases of convergent evolution in eukaryotes; and on …
