Gibberella
A genus of ascomycetous fungi of the family Hypocreaceae, order Hypocreales including several pathogens of grains and cereals. It is also the source of plant growth regulators such as gibberellin and gibberellic acid.
Fusarium
A mitosporic Hypocreales fungal genus, various species of which are important parasitic pathogens of plants and a variety of vertebrates. Teleomorphs include GIBBERELLA.
Trichothecenes
Fumonisins
A group of MYCOTOXINS found in CORN contaminated with FUSARIUM fungus. They are chains of about 20 carbons with acidic ester, acetylamino and sometimes other substituents. They inhibit ceramide synthetase conversion of SPHINGOLIPIDS to CERAMIDES.
Zearalenone
(S-(E))-3,4,5,6,8,10-Hexahydro-14,16-dihydroxy-3-methyl-1H-2-benzoxacyclotetradecin-1,7(8H)-dione. One of a group of compounds known under the general designation of resorcylic acid lactones. Cis, trans, dextro and levo forms have been isolated from the fungus Gibberella zeae (formerly Fusarium graminearum). They have estrogenic activity, cause toxicity in livestock as feed contaminant, and have been used as anabolic or estrogen substitutes.
