Outstanding Questions
1. What is the full network of auxin signalling, transport and response interactions during photoreceptor signalling?
2. How do natural combinations of light cues control the complexity of auxin-driven developmental plasticity?
3. Which spatiotemporal localisations of auxin transporters translate heterogeneous light cues to spatially explicit growth responses at the whole plant level?
