Many plants produce low-molecular-weight compounds which inhibit the growth of
phytopathogenic fungi in vitro. These compounds may be preformed inhibitors that are …

Tomatoes, a major food source for humans, accumulate a variety of secondary metabolites
including phenolic compounds, phytoalexins, protease inhibitors, and glycoalkaloids. These …

The aim of this study was to investigate the effect of tissue nitrogen concentration, as a
consequence of nitrogen supply rate, on the susceptibility of tomato plants to three …

Elemental sulphur (S0) is man's oldest fungicide. In biological systems it is formed by certain
specialized prokaryotes but the element has rarely been found in eukaryotes. The recent …

The observation that microorganisms develop tolerance to antimicrobial compounds when
constantly exposed to such chemicals is one of the most predictable and demonstrated …

Many plants produce antifungal secondary metabolites. These may be preformed
compounds which are found in healthy plants and which may represent in-built chemical …

Saponins are one of the most numerous and diverse groups of plant natural products. They
serve a range of ecological roles including plant defence against disease and herbivores …

Saponin detoxification enzymes from pathogenic fungi are involved in the infection process
of their host plants. Fusarium oxysporum f. sp lycopersici, a tomato pathogen, produces the …

Although Fusarium oxysporum pathogens cause severe wilts in about 80 botanical species,
the mechanisms of pathogenicity and symptom induction are poorly understood. Knowledge …

The gray mold pathogen Botrytis cinerea has a broad host range, causing disease in> 400
plant species, but it is not known how this pathogen evolved this polyxenous nature. Botrytis …
