Precocene II, a Trichothecene Production Inhibitor, Binds to Voltage-Dependent Anion Channel and Increases the Superoxide Level in Mitochondria of Fusarium graminearum
Precocene II, a constituent of essential oils, shows antijuvenile hormone activity in insects and inhibits trichothecene production in fungi. We investigated the molecular mechanism by which precocene II inhibits trichothecene production in Fusarium graminearum, the main causal agent of Fusarium head blight and trichothecene contamination in grains. Voltage-dependent anion channel (VDAC), a mit...
متن کاملFusarium graminearum Tri12p influences virulence to wheat and trichothecene accumulation.
The gene Tri12 encodes a predicted major facilitator superfamily protein suggested to play a role in export of trichothecene mycotoxins produced by Fusarium spp. It is unclear, however, how the Tri12 protein (Tri12p) may influence trichothecene sensitivity and virulence of the wheat pathogen Fusarium graminearum. In this study, we establish a role for Tri12 in toxin accumulation and sensitivity...
متن کاملCorrelation of ATP Citrate Lyase and Acetyl CoA Levels with Trichothecene Production in Fusarium graminearum
The correlation of ATP citrate lyase (ACL) and acetyl CoA levels with trichothecene production in Fusarium graminearum was investigated using an inhibitor (precocene II) and an enhancer (cobalt chloride) of trichothecene production by changing carbon sources in liquid medium. When precocene II (30 µM) was added to inhibit trichothecene production in a trichothecene high-production medium contai...
متن کاملRecombinant expression of the voltage-dependent anion channel enhances the transfer of Ca2+ microdomains to mitochondria
Although the physiological relevance of mitochondrial Ca2+ homeostasis is widely accepted, no information is yet available on the molecular identity of the proteins involved in this process. Here we analyzed the role of the voltage-dependent anion channel (VDAC) of the outer mitochondrial membrane in the transmission of Ca2+ signals between the ER and mitochondria by measuring cytosolic and org...
متن کاملThe voltage-dependent anion channel, a major component of the tRNA import machinery in plant mitochondria.
In plants, as in most eukaryotic cells, import of nuclear-encoded cytosolic tRNAs is an essential process for mitochondrial biogenesis. Despite its broad occurrence, the mechanisms governing RNA transport into mitochondria are far less understood than protein import. This article demonstrates by Northwestern and gel-shift experiments that the plant mitochondrial voltage-dependent anion channel ...
