Abstract

Citrus pectin induces highly synchronous differentiation in populations of zoospores in the absence of a host plant. This action is independent of the presence of Ca in the zoospore suspension medium. Water-soluble, ethanol-insoluble material present on the surface of the plant roots also induces differentiation of zoospore populations with the same time course as pectin. It is proposed that this material provides the natural recognition signal which induces zoospores to differentiate, and that pectin is sufficiently similar in structure for it to mimic its action.
