Abstract

The microscopic examination of Phytophthora cinnamomi in plant tissues is often difficult as structures such as hyphae, chlamydospores and oospores are frequently indistinguishable from those of other fungi and oomycetes, with histological stains not enabling species differentiation. This lack of staining specificity makes the localization of P. cinnamomi hyphae and reproductive structures within plant tissues difficult, especially in woody tissues. This study demonstrates that with the use of a species-specific fluorescently labelled DNA probe, P. cinnamomi can be specifically detected and visualized directly using fluorescent in situ hybridization (FISH) without damage to plant or pathogen cell integrity or the need for subculturing. This approach provides a new application for FISH with potential use in the detailed study of plant–pathogen interactions in plants.
