Trichothecene - an overview ScienceDirect Topic

  1. Trichothecenes belong to a large family of secondary metabolites, with over 150 members. They are primarily produced by species from the genus Fusarium, but also by isolates from the genera Myrothecium, Stachybotrys and Trichoderma. Trichothecenes occur in cereal grains such as wheat, barley, maize, oats and rice
  2. Trichothecene biosynthesis requires gene products from at least three loci in the Fusarium genome: the core trichothecene biosynthetic gene cluster (Brown et al. 2002a), the TRI101 locus (McCormick et al. 1999) and the TRI1 locus (Brown et al. 2003).The core trichothecene gene cluster consists of 12 open reading frames (ORFs) that encode both structural and regulatory genes (Fig. 3 B)
  3. Trichothecene is a type of mycotoxin produced by toxic molds. Trichothecene is one of the most notorious mycotoxins because trichothecenes are extremely toxic and because they are so difficult to destroy
  4. ants of livestock feed and some held to be found in yellow rain
  5. The trichothecene mycotoxins are a group of toxic secondary metabolites characterized by the tetracyclic 12, 13-epoxy trichothecenes, since they all have an olefinic bond at C9, 10 and the epoxy ring at C12,13 (Bamburg et al

The major products of the trichothecene mycotoxin biosynthetic pathway produced in a species- and sometimes isolate-specific manner by cereal-pathogenic Fusarium fungi include T-2 toxin, diacetoxyscirpenol, deoxynivalenol and nivalenol. This paper briefly reviews the major effects of such trichothecenes on the gross morphology, cytology and molecular signalling within eukaryotic cells Macrocyclic trichothecene-related diseases have received a number of specific names. The best known is stachybotryotoxicosis of horses, cattle, sheep, pigs, and poultry, first diagnosed in the former USSR but occurring also in Europe and South Africa.
