Abstract
Cyclic 3′,5′-adenosine monophosphate (cAMP) enhances the differentiation of chloronema cell type in the protonema cultures of the moss Funaria hygrometrica (1, 2). The endogenous level of cAMP is 4- to 7-fold higher in chloronema cells than that in caulonema cells (1). Thus there is a reduction in the cAMP level during caulonema differentiation. This could involve a modulation of adenylate cyclase and/or cAMP phosphodiesterase activity. Since the initiation of caulonema differentiation (3), and the activity of cAMP phosphodiesterase (4) depend on the amount of inoculum, we have investigated cell-density-mediated changes in cAMP phosphodiesterase activity in relation to caulonema differentiation.
