Abstract

In woody plants the periderm provides a formidable barrier to mechanical damage, and only a few fungal pathogens have been shown to directly penetrate suberised and/or lignified phellem cells. Recent research has shown that when the non-wounded periderm of Eucalyptus marginata (jarrah) seedlings are exposed to motile zoospores of P. cinnamomi, infection occurs and may result in seedling death. The current histological study was undertaken to determine how zoospores of P. cinnamomi circumvent the periderm.
