In developmental biology, photomorphogenesis is light-mediated development, where plant growth patterns respond to the light spectrum. This is a completely separate process from photosynthesis where light is used as a source of energy. Phytochromes, cryptochromes, and phototropins are photochromic sensory receptors that restrict the photomorphogenic effect of light to the UV-A, UV-B, blue, and red portions of the electromagnetic spectrum. WebMay 11, 2024 · Arabidopsis seedlings carrying cop1-weak alleles exhibit strong photomorphogenic developmental patterns even in complete darkness, with typical short hypocotyls as well as open and expanded cotyledons (Deng and Quail, 1992, McNellis et al., 1994).The nuclear accumulation of COP1 can be drastically reduced by extended light …
