Tri5 is involved in the catalysis of the following reaction: 2-trans, 6-trans-farnesyl diphosphate = diphosphate + trichodiene. The TRI5 gene was first characterised in a F. sporotrichioides strain that produced T-2 toxin . The trichodiene ...
WebMar 1, 2024 · The expression of the trichodiene synthase tri5 gene of Trichoderma arundinaceum in a T. harzianum mutant which produced lower levels of ergosterol resulted in trichodiene production, accumulation of the ergosterol-precursor squalene and elicitation of plant defences (Malmierca et al., 2015b). WebJan 1, 2024 · The first pathway intermediate, trichodiene, is formed by cyclization of FPP, a reaction that is catalyzed by the trichodiene synthase (TRI5). Trichodiene then undergoes a series of cyclization, oxygenation, and acylation reactions to form trichothecene analogs such as HA and trichodermin.
