Abstract

Almond domestication is marked by the selection of sweet kernel genotypes. A recent study (Sánchez-Pérez et al.) reveals that a nonsynonymous point mutation in a bHLH transcription factor prevents transcription of the two P450 genes in the amygdalin biosynthetic pathway, resulting in the sweet kernel trait.
