Discovery of iridoid cyclase completes the iridoid pathway in asterids - Nature Plants
Iridoids are terpenoid metabolites found in thousands of plants. Using single-cell transcriptomics, the authors discovered an unexpected enzyme that has been neofunctionalized to catalyse the cyclization required to form the iridoid scaffold.

Iridoids are widespread cyclic monoterpenes associated with plant defense and essential precursors for the lab’s favorite monoterpenoid indole and ipecac alkaloids. They are ancestral to asterids but have been lost and re-invented at least once (check out @lichmanlab.bsky.social past work on catnip)

Ribes (genus of gooseberries (as you know them) and currants) has about 200 species. It's the only genus in its family. That makes it sort of a midsized family. But for contrast, there's ~32k asterids, ~28k orchids, ~20k legumes, ~13,5k madders, ~12k grasses, etc.

The iridoid pathway is very old and ancestral to all asterids. Iridoid synthase (ISY) was identified more than a decade ago and generates the reactive enol intermediate priming the molecule for cyclisation. Although limited spontaneous cyclisation can happen in vitro it does not happen in vivo.

Datura wrightii Regel
Datura wrightii, commonly known as sacred datura, is a poisonous perennial plant species and ornamental flower of the family Solanaceae native to the Southwestern United States and northwestern Mexico. It is sometimes used as a hallucinogen due to its psychoactive alkaloids. D. wrightii is classified as an anticholinergic deliriant.
Common names in the US include "sacred thorn-apple" or "hairy thornapple",[2] and sometimes "western Jimson weed"[4] because of its resemblance to Datura stramonium due to both species having toothed leaves.

The colors are definitely similar, and they’re both part of the asterids clade 😊
I think a major differentiation is that bugle has flowers growing densely all up its stem, while borage has individual extensions at the end of the branch with flowers hanging down from it 🤔

Notes: 1) MYA = million years ago.
2) Tyrannosaurus rex lived ~75-66 MYA.
3) Iridoid biosynthetic genes are conserved in basal groups of Asterids, such as Cornales & Ericales (the order which contains blueberries).

#PlantScience fact that you don't need: iridoids, found in plants in the Asterid clade, are the precursor to many natural products, e.g., oleuropein (the bitter compound of olives) & vinblastine (anticancer drug from periwinkle). Asterids emerged ~115 MYA, thus iridoids are older than T. rex.
