Blue light perceived by phototropin orients the asymmetric division of Marchantia polymorpha spores, controlling the direction of the earliest developmental axis.
- Why it matters: Early plant development starts from a single spore, and how an external directional cue sets the orientation of the first symmetry axis is not well defined.
- What they did: The study tested whether blue light acts through phototropin and whether downstream signaling requires NCH1, using Marchantia polymorpha spore development and division orientation readouts.
- The result: Blue-light–dependent phototropin signaling that requires NCH1 is linked to correct orientation of asymmetric spore division, thereby orienting the first axis of symmetry.
