Despite the centrality of the cell in living systems, the evolutionary origin and diversification of different cellular features remain poorly understood. This represents a major deficiency in our understanding of the process of evolution, as the establishment and modification of such features have surely constituted important substrates for evolution ever since the emergence of the first cell. In our lab, we aim to contribute towards bridging the gap between cell and evolutionary biology, through the study of the emergence and diversification of the dynamic cellular features that characterize bacterial endospore formation.

Endospore formation (aka sporulation) is a developmental process that culminates with the formation of resilient spores. It is a trait found in a range of bacterial species that belong to an ancient and exceptionally diverse bacterial phylum, the Firmicutes. The process gathers the necessary ingredients to address key questions in evolutionary cell biology. Firstly, sporulation involves dramatic changes in cellular architecture, and those changes can be easily tracked in real time using microscopy. Secondly, endospore formers are typically unicellular and sporulation involves the participation of a small number of cells (only two cells in many cases), so changes in cellular architecture are expected to have readily observed effects at the organismal level. Thirdly, although the evolutionary origin of sporulation is monophyletic, the process has diversified throughout evolution, providing the substrate to perform comparative genomic and cytological studies and to address key questions such as the adaptive value of specific cytological changes.

In our lab, we take pleasure in combining lines of reasoning inspired by classical bacterial genetics with cutting-edge cell biological tools to obtain mechanistic details about how sporulation cellular dynamics functions and evolves. We aim to understand not only how cells are, but also how they became the way they are.
