WebJan 17, 2011 · The identification of the genetic basis of botcinic acid biosynthesis is a prerequisite for studying the role of this toxin and the proposed redundant effect with botrydial during pathogenesis. The biosynthetic origin of the botcinic acid skeleton has been investigated previously by feeding B. cinerea with 13 C- and 2 H-labelled precursors.

(2024) have also reported that high temperature resulted in decreased expression levels of ABA and the botrydial gene cluster, which in turn led to suppression of pathogenicity by the Ct3 fungus [60]. WebJan 26, 2024 · Recently, the genetic and molecular basis of botrydial biosynthesis have been described [36,37]. Genes Bcbot3 and Bcbot4 were deleted by homologous recombination and showed to catalyse regio- and stereospecific hydroxylation at the C-10 and C-4 carbons, respectively, of the probotryane intermediate skeleton ( Figure 9 ) [ 36 ].
WebSep 1, 2016 · Parts of the plants may be killed by the phytotoxin botrydial, enabling the fungus to feed on the dead cells. In this paper, we describe the genetic and molecular basis of botrydial biosynthesis and the function of the five genes of the genome of B. cinerea that together constitute the botrydial biosynthetic gene cluster. WebBotrydial (1) is the major phytotoxin14,15 of B. cinerea, and it has been shown to reproduce the symptoms of the infection.16,17 Spectroscopic, chemical, and X-ray methods18−20 were used to establish the irregular sesquiterpenoid structures of these botryane metabolites.
