COVER The cryptochromes are photoreceptors through which cells respond to blue light. A Review by Cashmore et al. (p. 760) in the special section on Signal Transduction (beginning on p. 755) summarizes recent evidence that cryptochromes function not only in regulation of plant growth, but also in entrainment of the endogenous biological clocks of a broad range of organisms-from plants and insects to mammals.
