TLDR
All isolates of F. roseum “Graminearum” which formed the perithecial stage of G. zeae (G.roseum) produced zearalenone, and production by F. tricinctum was confirmed by a mouse bioassay.Abstract:
One-hundred-and-thirteen isolates of Fusarium were tested for their ability to produce zearalenone on autoclaved corn. They belonged to the following species (number of producers per number tested): F. epispheria, (0/1); F. moniliforme, (0/8); Gibberella fujikuroi, (0/3); F. nivale, (0/7); F. oxysporum, (0/15); F. roseum, (31/51); F. solani, (0/9); F. tricinctum (3/19). The isolates of individual species produced the following amounts of zearalenone per gram of corn: 3 isolates of F. roseum (0.6 to 119 mug), 3 of F. roseum "Culmorum" (1 to 210 mug), 3 of F. roseum "Equiseti" (0.6 to 2.0 mug), F. roseum "Gibbosum" (115 to 175 mug), 21 of F. roseum "Graminearum" (0.2 to 230 mug), and 3 of F. tricinctum (0.2 to 6.0 mug). All isolates of F. roseum "Graminearum" which formed the perithecial stage of G. zeae (G. roseum) produced zearalenone. Production occurred by the wild but not the appressed cultural type. Zearalenone production by F. tricinctum was confirmed by a mouse bioassay.read more

Naturally occurring oestrogens in foods—A review
K. R. Price,G. R. Fenwick +1 more
TL;DR: Indications are given of the wide range of common food plants which have been reported to possess oestrogenic (uterotropic) activity, although it is emphasized that in general further work is necessary to substantiate these claims and to confirm the identities of the biologically active principles which have in some cases been proposed.

Identification of T-2 Toxin in Moldy Corn Associated with a Lethal Toxicosis in Dairy Cattle
TL;DR: T-2 toxin at concentrations of 2 mg per kg of dry corn was identified in purified extracts of the moldy corn by means of gas-liquid chromatography and mass spectrometry and the nature of the toxic effects observed strongly suggest a major causal relationship.

TL;DR: Experiments in vivo and in vitro indicate that ZEA and its metabolites are substrates for various enzymes involved in steroid metabolism, considering the interaction with estrogen receptors mentioned above.

Zearalenone and Some Derivatives: Production and Biological Activities
TL;DR: This chapter discusses the production and biological activities of zearalenone and some derivatives, and the pair of diastereoisomers obtained by catalytic reduction of the parent compound exhibited properties suggesting possible value in treatment of the postmenopausal syndrome.

TL;DR: Despite no effect on haematological parameters, ZEA caused thymic atrophy with histological and thymocyte phenotype changes and decrease in the B cell percentage in the spleen and ZEA is an immunotoxic compound similar to estrogen and some endocrine disruptors.

TL;DR: The typical New Jersey corn stalk-rotting strain of G. zeae does not sporulate in laboratory surface culture, and produces abundant, typical macrospores only in shake-based culture.
