Description
Makarim Elfadil M Osman and co-authors trace, in 2026, the evolution of terpene synthase genes in coffee, the family that builds aroma-related terpene compounds. Coffea arabica is a hybrid species formed from two diploid parents, so its gene family carries a double inheritance. How that family expanded and diversified was the question.
Genome searches found 69 family genes in arabica, against 40 and 55 in its two parent species. Tandem duplication, where copies arise side by side, drove most expansion, and arabica mostly kept parental copies under strong purifying selection. Gene activity data across tissues showed many copies active with specific patterns, some shared between duplicates and some diverging, linking evolution to regulation.
