Stereochemical insights into sarpagan and akuammiline alkaloid biosynthesis

New Phytologist, EarlyView.
Summary Sarpagan and akuammiline monoterpenoid indole alkaloids (MIAs) are a class of bioactive plant‐derived compounds with significant pharmaceutical potential. These alkaloids are formed through oxidative cyclization of geissoschizine, catalyzed by homologous cytochrome P450 monooxygenases (CYP) known as sarpagan bridge enzymes (SBEs) and rhazimal ...

Plants, Pollinators and Pheromones: Promises and Lies of Semiochemicals

Plant, Cell &Environment, EarlyView.
ABSTRACT Pollination is traditionally regarded as a quintessential mutualism, yet many plants employ deceptive strategies to achieve reproductive success. Among the most intriguing is sexual deception, wherein flowers mimic the sex pheromones and visual signals of female insects to attract male pollinators—without providing any reward.

Ontogeny and organ‐specific steroidal glycoside diversity is associated with differential expression of steroidal glycoside pathway genes in two Solanum dulcamara leaf chemotypes

Plant Biology, EarlyView.
Steroidal glycoside diversity among organs across ontogeny in relation to candidate gene expression in two Solanum dulcamara chemotypes. Abstract Solanaceous plants, such as Solanum dulcamara, produce steroidal glycosides (SGs). Leaf SG profiles vary among S.

Characterization of switchgrass (Panicum virgatum L.) PvKSL1 as a levopimaradiene/abietadiene‐type diterpene synthase

Plant Biology, EarlyView.
This study reports the discovery and functional characterization of PvKSL1, a previously unrecognized class I diterpene synthase from switchgrass. Abstract The diverse class of plant diterpenoid metabolites serves important functions in mediating growth, chemical defence, and ecological adaptation. In major monocot crops, such as maize (Zea mays), rice
