▶ AI Summary
The study compares two Assyrtiko grape clones (A16 and E11) grown in Nemea, revealing distinct aromatic profiles linked to differential terpene and volatile thiol production. Integrated chemical and transcriptomic analyses identified up‑regulated biosynthetic genes in each clone, and five candidate enzymes were functionally characterized in yeast, elucidating key pathways governing aroma diversity in Vitis vinifera cv. Assyrtiko.
