The identification of a self-inhibitor from Syncephalastrum racemosum and its effect upon sporangiospore germination

High concentrations of Syncephalastrum racemosum spores germinated less readily than low concentrations. Extensive washing of spores alleviated this inhibition of germination. Analysis of the spore washings revealed the main constituent to be nonanoic acid. Exogenously added nonanoic acid was found...

Summary:High concentrations of Syncephalastrum racemosum spores germinated less readily than low concentrations. Extensive washing of spores alleviated this inhibition of germination. Analysis of the spore washings revealed the main constituent to be nonanoic acid. Exogenously added nonanoic acid was found to mimic the self-inhibition, in that it delayed the time of germ tube emergence and increased the lag before spore swelling commenced.
