Phytochrome-mediated control of photomorphogenesis is linked to many other gene functions. The following statements are made on the mechanism of phytochrome action:
a) COP1, negative regulator of photomorphogenesis, is a component of the E3 ubiquitin ligase complex that targets photomorphogenesis-promoting proteins for degradation such as phyA
b) Light-dependent export of COP1 to the cytoplasm is a slow process, requires long exposure to light
c) The absence of COP1 in the cytosol permits the accumulation of transcriptional activators necessary for photomorphogenic development
d) The COP1–SPA1-E3 ligase complex is also responsible for the ubiquitination and proteasomal degradation of photomorphogenesis-promoting proteins, such as HY5
