Abstract

Powdery mildews are obligate pathogens. The fungus grows externally on leaf tissues and forms haustoria only in host epidermal cells. The haustorium is believed to be the absorptive organ through which the fungus acquires photosynthates for growth. The intimate interface established between fungus and host and subsequent alterations made to the region of the host plasmalemma in direct contact with the haustorium [1] may aid this function.
