Parallel evolution in this case could be indicative of positive selection to produce the metabolite in this environment.
Indeed, plants carrying different alleles of GH38cv present different accumulation of the metabolite, and germinate, grow and reproduce better under high salt concentrations.

Looking at genome sequences from a global set of Arabidopsis plants (~1600), only two populations have non-functional aleles of GH38cv, and both come from the Cape Verde archipelago, but each population comes from a different island!
This is a case of parallel evolution!

We performed metabolite QTL analysis in a plant population derived from Cape Verde Islands (Cvi-0) and central Europe (Col-0).
The strongest QTL is in an unidentified metabolite.
We characterize the metabolite as glucuronyl-mannose, and we map the gene to a glycoside hydrolase family 38 (GH38cv).

Congratulation to all authors!

These were my very first experiments done at @cbgpmadrid.bsky.social. I still remember the excitement of @jimenezgomez.bsky.social and me when observing the plates and the shocking phenotype!
Thanks to all the authors for the work and so happy to continue working on this!
