Lateral inhibition governs ancestral cellular patterning in fossil and extant liverworts

Highlighted Article: Comparative and mathematical analyses reveal that oil body cell patterning in fossil and extant liverworts is consistent with a local activation-lateral inhibition mechanism, poin...

Have you ever heard that women have more chances than men of getting grants or positions in academia? Of course you have, and here are my personal views on this. With the shocking revelation that no, it is NOT TRUE ! (1/n)

Interested in fossils, evo-devo, and how mathematical modeling can help us understand the evolution of developmental processes? In our latest preprint, we uncover an ancestral lateral inhibition mechanism underlying epidermal patterning in liverworts.

Happy to see this out! We describe a patterning mechanism underlying rhizoid specification in Marchantia. Contrary to classic patterning mechanisms (e.g., Turing), rhizoid specification depends on both randomness and lateral inhibition, involves subcritical bifurcations, and occurs at criticality!

Cell-type specification at criticality underlies rhizoid patterning in the liverwort Marchantia polymorpha

Rhizoid specification in Marchantia polymorpha gemmae involves lateral inhibition mediated by the microRNA FRH1, which represses the rhizoid-specific …
