Antifungal activity to Phytophthora infestans and toxicity to tuber tissue of several potato phytoalexins.

An antifungal metabolite, oosporein, was isolated from the culture of Verticillium psalliotae that produced the antagonistic effects on Phytophthora infestans. Oosporein exhibited a significant growth-inhibitory effect on P. infestans in comparison with other phytopathogenic fungi.

Leaf Extracts

In vitro evaluation of antifungal activity by disc diffusion method was carried out on leaf extracts of D.falcata, D. falcata var pubescens, V. monoicum and V. orientale and stem extracts of D. falcata, D. falcata var pubescens, V. articulatum and V.orientale using three different solvents viz., methanol, n-hexane and ethyl acetate. The antifungal activity was tested on three fungal strains include Fusarium oxysporum, Phytophthora infestans, Sclerotium rolfsii. Overall leaf extracts exerted better inhibitory activity than stem counterparts. Among all, only V. orientale was effective against the three fungal species.Compared to stem extracts, leaf extracts of D. falcata var pubescens have shown higher antifungal activity.

Extrahaustorial Matrix

Host–parasite interfaces in potato tubers (Solanum tuberosum) of a resistant (Eba) and a susceptible (Bintje) cultivar inoculated with Phytophthora infestans were studied with transmission electron microscopy. In the resistant host the fungal haustoria are typically small and surrounded by an electron-dense extrahaustorial matrix and electron-transparent wall appositions, normally in form of complete encasements. Wall appositions are generally lacking in the susceptible host or occasionally are found as a collar at the base of the rather large haustorium, which is surround by a well developed extrahaustorial matrix. Since wall appositions probably contain largely a callose-like material, potential roles of fungal glucanases in this host–parasite system are discussed.
