The family of phytochrome-like photoreceptors: diverse, complex and multi-colored, but very useful

- All three groups of phytochrome-like photoreceptors are structurally characterized.
- By color-fine tuning phytochromes cover the whole spectrum from UV to NIR.
- Phytochrome-like photoreceptors form a family with highly diverse photochemistries.
- Phytochromes' diversity makes them to interesting targets for synthetic biology.
