A fumonisin is a mycotoxin derived from Fusarium, Liseola section.[1] They have strong structural similarity to sphinganine, the backbone precursor of sphingolipids[2]

More specifically, it can refer to:

The trichothecene (T-2) mycotoxins are a group of over 40 compounds produced by fungi of the genus Fusarium, a common grain mold.[3]

The estrogenic metabolite, zearalenone, is also referred to as F-2 toxin.[4]

As the fumonisins appear to be non-genotoxic the possibility that they belong to another class of non-genotoxic carcinogens, the peroxisome proliferators, was investigated[5]

Genetic engineering is reported as a promising means of detoxifying mycotoxins. This approach may provide innovative solutions to the problem of fumonisin in corn.[6]

At least 15 different fumonisins have so far been reported and other minor metabolites have been identified, although most of them have not been shown to occur naturally.[7] In 2015, a unique class of non-aminated fumonisins[8] was reported on grapes infected with Aspergillus welwitschia, although their toxicities have not yet been established.
