PHYTOALEXINS: What Have We Learned After 60 Years?
TL;DR: Evidence in support of phytoalexins in resistance as well some recent advances in phy toalexin biosynthesis are reviewed and criteria for evaluating a role for phy ToALxin in disease resistance are discussed.

TL;DR: Using the technique of differential display, a maize transcript was identified whose silk tissue expression is induced in the presence of the ear rot pathogen Fusarium graminearum, and it was demonstrated that both AN1 and AN2 are ent-copalyl diphosphate (ent-CPP) synthases (ent -CPS).
Journal ArticleDOI
The oldest fungicide and newest phytoalexin - a reappraisal of the fungitoxicity of elemental sulphur
TL;DR: The recent discovery that certain plant species from diverse families produce S0 as a localized component of active defence to vascular pathogens, and that S0 is constitutive in some crucifers, led to this review.

TL;DR: It is suggested that early flavonoid accumulation is associated with the hypersensitive reaction of cotton cotyledons toX.

Quantitative Localization of the Phytoalexin Glyceollin I in Relation to Fungal Hyphae in Soybean Roots Infected with Phytophthora megasperma f. sp. glycinea
TL;DR: The hypothesis that the accumulation of glyceollin I is an important early response of soybean roots to infection by P. megasperma is supported, but may not be solely responsible for inhibition of fungal growth in the resistant response.

Glyceollin: its rôle in restricting fungal growth in resistant soybean hypocotyls infected with Phytophthora megasperma var. sojae
TL;DR: Results strongly suggested that glyceollin accumulation accounts for cessation of fungal growth in the resistant soybean hypocotyls.
Journal ArticleDOI
Accumulation of sorghum phytoalexins induced by Colletotrichum graminicola at the infection site
TL;DR: Microspectrophotometry was performed on intact, pigmented vesicle-like inclusions within living sorghum cells that were accumulating phytoalexins as a response to attempted fungal infection and confirmed that at the infection site the deoxyanthocyanidins accumulate to levels in substantial excess of those required for inhibition of the fungus.
