International audience. Earth as we know it today has been shaped by key geological and biological events over the last billion years. One of these founding events, was the colonization of land by the aquatic ancestor of all extant terrestrial plants, the plant terrestrialization, which took place half a billion years ago. While the biology and genetics of terrestrial plants has been deciphered for decades by scientists, our understanding of their closely related green algal cousins remain elusive. By developing models in the sister clade to the terrestrial plants, we aim at better understanding this ignored part of the tree of life and, by comparative approaches, to predict the biology of the first land plants.
