Abstract: | Derivatives of cyclic-3′,5′-adenosine monophosphate, N6,2′-O-dibutyryl-cAMP, 8-(chlorophenylthio)-cAMP and 8-bromoadenosine-cAMP added at 0.1–10 μmol/L concentrations into the growth
medium have markedly stimulated conidiation inTrichoderma viride. Their stimulatory effect on conidiation was best observed in colonies that were constantly kept in the dark but was also
marked in colonies illuminated by sub-saturating doses of light. The relative stimulation of conidiation depended not only
on the concentration of exogenous cyclic nucleotides but also on the concentration of glucose in the medium. It was more pronounced
in glucose-rich media than in media where the concentration of the sugar was low. Concentrations of cAMP analogues equal to
50 μmol/L and higher inhibited the conidiation. |
