Rapid freezing and freeze substitution (RF-FS) have been used to re-examine the process by which the multinucleate sporangium of the Oomycetes, Phytophthora cinnamomi and P. palmivora, is subdivided into uninucleate zoospores. The results indicate a new model for sporangial cleavage in Phytophthora and suggest that the currently accepted model is based on interpretation of artefacts caused by chemical fixation. The previous model describes cleavage as a two-stage process in which specialized… CONTINUE READING
