Rocksitter Flies (Lauxaniidae: Cestrotus) are Key‐Pollinators of Ceropegia pulchellior—A Threatened and Localised South African Endemic With Foetid‐Scented Flowers

open access: yesJournal of Applied Entomology, Volume 149, Issue 6, Page 888-900, July 2025.
ABSTRACT Short‐tongued saprophilous flies are a diverse but under‐appreciated group of pollinators, which are particularly important for flowers in the subtribe Stapeliinae (Apocynaceae‐Asclepiadoideae‐Ceropegieae). This clade of plants is characterised by repeated shifts between tubular kettle‐trap and open non‐trap flowers and chemical mimicry (of ...

Beyond defense: microbial modifications of plant specialized metabolites alter and expand their ecological functions

open access: yesNew Phytologist, Volume 247, Issue 2, Page 518-526, July 2025.
Summary Plant specialized metabolites (PSMs) are compounds that are not involved in primary metabolism but instead confer other roles for the plant host, often related to ecological interactions. In the field of plant–microbe interactions, many PSMs have traditionally been considered for their roles in shaping interactions with pathogens.

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine

open access: yesAngewandte Chemie, Volume 137, Issue 24, June 10, 2025.
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
