The role of <i>Fragaria vesca</i> homolog of a (Z)-3:(E)-2-hexenal isomerase in the development of green-leafy fruit aroma.

ABSTRACT: The green leaf volatiles (Z)-3-hexenal and (E)-2-hexenal are key components of the characteristic strawberry aroma, an important determinant of consumer preferences. Green leaf volatiles (GLVs) are C6 compounds that impart fresh, green notes and are involved in plant wounding responses. GLV biosynthesis requires several enzymatic steps to convert polyunsaturated fatty acids to C6-aldehydes, alcohols, and esters, respectively. However, the biosynthesis of GLVs in strawberries, such as the isomerization of (Z)-3-hexenal to (E)-2-hexenal, remains poorly understood. In this study, we identified a (Z)-3:(E)-2-hexenal isomerase gene (FvHI) using phylogenetic analysis, characterized its expression in different tissues, and characterized its function using stable transformation.
