Common Name

PR-toxin

Description

PR-toxin is a mycotoxin belonging to the chemical class of secondary metabolites produced by the mold Penicillium roqueforti. This mold is renowned for its role in the production of blue-veined cheeses, contributing to their distinctive texture and aroma. PR-toxin is synthesized alongside other metabolites such as andrastins and mycophenolic acid, and it plays a significant role in the ecological interactions of the fungus. Research indicates that PR-toxin is involved in inhibiting mycelium growth and altering the morphology of fungal structures, which includes damaging hyphae and microconidia. Furthermore, it has been shown to decrease DNA content and interfere with the synthesis of other fungal toxins, such as patulin and roquefortine C, while also downregulating key genes associated with toxin biosynthesis pathways (PMID:36777030 ). Additionally, conservation analysis of biosynthetic gene clusters suggests that mycotoxin analogs of PR-toxin may also be produced by other fungi, such as those in the Cordyceps genus (PMID:32575649 ). This highlights the broader significance of PR-toxin within the context of fungal secondary metabolite production and its potential ecological impacts.
