WebWe also found that QoIs can accelerate the formation of toxisomes and enhance the fluorescence signals of Tri-GFP labeled toxisomes, which may be due to the effect of QoIs on toxisome-related endoplasmic reticulum-remodeling. In addition, QoIs could disrupt the homeostasis of mitochondrial dynamics, resulting in the fragmented mitochondria. WebDON is synthesized in specialized subcellular structures called toxisomes. The first step in DON synthesis is catalyzed by the sesquiterpene synthase (STS), Tri5 (trichodiene synthase), resulting in the cyclization of farnesyl diphosphate …
