Plants respond to many stress factors, including infections caused by root pathogens, with reductions in photosynthesis and growth. We studied the response of mature cucumber plants after a weak inoculation of the roots with Pythium aphanidermatum . The epidemiology of the disease was recorded using an indirect ELISA. Although mycelium was detected in the roots, photosynthesis was not affected over a period of five weeks. Nevertheless, plant growth was significantly reduced by the pathogen. Possible modes of action are discussed.
