Levels of the cyclic nucleotides, cAMP and cGMP, were determined in four species of pennate diatoms; changes in their levels and ratios were monitored in silicon-starved and light-dark synchronized cultures of Cylindrotheca fusiformis. Content of both cAMP and cGMP changed during the cell cycles: when silicate was added to starved cultures, cAMP, cGMP and DNA levels rose rapidly; cAMP and cGMP declined befor DNA synthesis was complete and continued to fall during the events leading to cell separation. In unstarved synchronies, net synthesis of DNA continued until cell separation; 1 h before cell separation cAMP levels fell while those of cGMP rose. The results support of the proposal that cAMP and cGMP may play a part in the process of cell division in the diatom, possible involving silicon.
