โœฆ Synopsis

The resumption of development upon light activation of Artemia embryos is accompanied by an immediate drop in cyclic adenosine monophosphate (CAMP) concentration. The concentration of cyclic guanosine monophosphate (cGMP) remains unaltered, however. A similar effect is observed when the cysts are treated with HzOz, with which we demonstrated that its action mimics light activation. The demonstrated decrease in cAMP is the earliest observed intracellular event after light induction. Possible regulatory roles of cyclic nucleotides in light-induced resumption of development are discussed.

## Abstract ## Background Cysts of __Artemia__ can remain in a dormant state for long periods with a very low metabolic rate, and only resume their development with the approach of favorable conditions. The post-diapause development is a very complicated process involving a variety of metabolic an
