报告摘要：

Light is very important for the plant, not only because of the photosynthesis, but also because of the photomorphogenesis, light controls the development of plants. Plants have several kinds of photoreceptors to mediate light signal transduction. The photolyase-like blue-light receptors cryptochromes (CRYs) were initially identified in Arabidopsis (Arabidopsis thaliana) and later found in almost all species examined. The talk is going to focusing on how blue light and temperature coordinate to regulate development. We show that CRY is critical for not only blue light signaling but also ambient temperature responses. The pleasant green color of the green plants is caused by their reflectance of green light. This might give the impression that green plants can not absorb and use green light, and green light is of minor importance to green plants. We find that green plants absorb green light, and green light promotes the elongation of hypocotyls in Arabidopsis and many other plant species, which is contrary to the function of all other known spectra in photomorphogenesis.
