Photomorphogenesis: responding to light
1) Photoreceptor: intrepert light signal
Phytochromes absorb red and far red light.(chromoproteins)
‒ Cryptochromes detect blue and UV-A light.(also)
‒ Phototropins also detect blue and UV-A light.(also)
‒ A newly-identified class of photoreceptors that responds to low levels of UV-B light.
photoreversible, red ligt stimulates germination, far red =germination back off
2) Phytochromes: phycobiliprotein, signal transduction,DNA repair enzyme,
3) Cryptochrome: signal transduction
4) UV-B light response
