A collage showing on the left a picture of the bright pink closed flowers and bracts of the plant Pogonopus speciosus. On the right a scheme depicting the reaction of tryptamine and secologanic acid to vincosidic acid that is catalyzed by P. speciosus Epi-STR, an unusual R-stereoselective ortholog of strictosidine synthase.

Our funky R-stereoselective Epi-STR is now available online and open access at its permanent home @angewandtechemie.bsky.social. 🥳
This is Clara's first first-author paper, makes me extra happy!

Complete biosynthesis of nicotine Glycosylation and deglycosylation complete nicotine biosynthesis by enabling stereoselective condensation of its two heterocyclic rings within a vacuolar membrane metabolon. This integrated biosynthetic and transport machinery is transferable to heterologous systems for efficient nicotine production and pest resistance.

Hi - we are looking for a PhD student to finish the thapsigargin biosynthesis. If you are up for some great work, then apply.

We have been cooking up this story for a while and we are excited to finally be able to share!

Read on if you're interested in whole plant regeneration WITHOUT the application of hormones!

We are very close to reaching the registration cap for MECS2026. Given the strong interest, we have increased the number of participants from 100 to 120 and extended registration until April 12. Please note, however, that we can no longer accept poster submissions.

The fact that Americans thought Auxin was a “Hoax from Europe” rightfully got some attention in my latest #PlantScienceClassics post. But it’s actually even funnier if you learn about the context & consequence of White speaking these words to Went at the AAAS Meeting in Pittsburgh. #PlantScience 🧪

The authors of the two papers. Carlos O. Miller standing on the left, looking down upon a couple of glass beakers. Opposite him, from the back to the front, are Malcolm H. van Saltza, Francis Shigeo Okumura, Folke K. Skoog and Frank M. Strong. Below the photo are the headers of their two papers describing kinetin, the first cytokinin: “Kinetin, a cell division factor from desoxyribonucleic acid” by Carlos O. Miller, Folke K. Skoog, Malcolm H. van Saltza and Frank M. Strong, and “Structure and synthesis of kinetin” by Carlos O. Miller, Folke K. Skoog, Francis Shigeo Okumura, Malcolm H. van Saltza and Frank M. Strong. Both published in 1955 in the Journal of the American Chemical Society.

Well.. we indeed had g&t at the acceptance celebration of the quinine paper but believe it or not it was with alcohol-free gin 😂

Mystery of quinine biosynthesis solved For centuries, the process by which the cinchona tree produces its valuable alkaloids, including the life-saving quinine used to treat malaria, was shrouded in mystery. Now, a research team from the M...

The process by which the cinchona tree produces quinine has been elucidated. In a new study published in @nature.com, researchers from the @oconnorlab.bsky.social and the @universityofga.bsky.social unveil the biosynthetic pathway behind this 400-year-old secret.
