Regulation of fumonisin B(sub 1) biosynthesis and conidiation in Fusarium verticillioides by a cyclin-like (C-type) gene, FCC1

Article Abstract:

Researchers have discovered a gene that regulates the production of fumonisin B(sub 1) as well as conidiation in Fusarium verticillioides. Fumonisins are mycotoxins that contaminate corn and corn products.

PAC1, a pH-regulatory gene from Fusarium verticillioides

Article Abstract:

Research has been conducted on Fusarium verticillioides. The authors describe the isolation and characterization of cloned PACC-like gene from this bacterium, and suggest that this gene is responsible for fumonisin biosynthesis under alkaline conditions.

Regulation of fumonisin biosynthesis in fusarium verticillioides by a zinc binuclear cluster-type gene, ZFR1

Article Abstract:

A study is conducted to identify a candidate regulatory gene, ZFR1in an expressed sequence tag library enriched for transcripts during fumonisin B1 /(FB1) biosynthesis. The results of the study indicate that ZFR1 is a positive regulator of FB1 biosynthesis in F. verticilliodes and suggest that FCC1 is required for ZFR1 function.
