Abstract excerpt

Gravitropism is a plant response to gravity that directs organ growth and development, playing a key role in the adaptation of land plants. While its molecular basis has been extensively studied in flowering plants, much less is known about this process in other plant lineages. Here, we investigated the gravitropic response of the liverwort Marchantia polymorpha, a model for early land plant evolution. In...
