Abstract
Adenylyl cyclase activity of Evernia prunastri thalli is enhanced by r ed light pulses in a two-step way: a very rapid increase of activity a fter the first 5 min of red light, which is not inhibited by cyclohexi mide, and a slow enhancement following successive red light pulses at the beginning of each 30 min incubation. The last response is complete ly reversed by far-red following red light and inhibited by cyclohexim ide.
