摘要: Apical hook opening and cotyledon unfolding are characteristic responses that occur during deetiolation of dicotyledonous seedlings. Light-stimulated apical in etiolated Arabidopsis thaliana seedlings appears to involve the activities multiple photosensory systems. Red, far-red, blue light all effective stimulating these Arabidopsis. Stimulation by red low fluence is inductive, far-red reversible, exhibits reciprocity, as many fluence-dependent phytochrome-mediated responses. Far-red high-fluence appear stimulate through high-irradiance-response systems long-term treatments. Although a phytochrome system presumably mediates light, may be mediated light-specific system.
