Cryptogam blue-light photoreceptors

Current Opinion in Plant Biology, 2003
Blue light regulates various aspects of plant development. Extensive research using Arabidopsis thaliana has advanced our understanding of blue-light photoreceptors and signal transduction pathways in flowering plants, but our knowledge of blue-light signaling in other plant systems, particularly in cryptogams (i.e.
