WebNov 18, 2004 · Plant blue-light photoreceptors. Presentation of the Arabidopsis thaliana photoreceptor proteins. Three cryptochromes (cry1, cry2, cry3) were identified in Arabidopsis. The highest conservation among the cryptochrome sequences is found in the photolyase (PHR)-related part ( hatched part ). WebCryptochromes receptors cause plants to respond to blue light via photomorphogenesis. They help control seed and seedling development, as well as the switch from the vegetative to the flowering stage of development. In Arabidopsis, it has been shown that cryptochromes controls plant growth during sub-optimal blue-light conditions.
