Adenosine 3',5'-cyclic monophosphate levels in normal and IAA-induced tumours in bean (Phaseolus vulgaris L.) embryos.

Endogenous levels of adenosine 3',5'-cyclic monophosphate in indole-3-acetic acid induced tumours, and control bean embryos were measured with Gilman protein binding assay. No significant differences in cAMP concentrations were found in IAA-induced tumours, which suggests that IAA does not mediate cAMP synthesis in bean embryos.
