BpWRKY6 regulates insect resistance by affecting jasmonic acid and terpenoid synthesis in Betula platyphylla

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Forest pests and diseases pose serious threats to the sustainable development of forestry. Plants have developed effective resistance mechanisms through long‐term evolution. Jasmonic acid and terpenoids play important roles in the defence response of plants against insects.

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine. [PDF]

open access: yesAngew Chem Int Ed Engl
19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals
