A complex mixture of hundreds of substances determines strawberry (Fragariaxananassa) aroma, but only ~15 volatiles are considered as key flavour compounds. Of these, 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF) is regarded as the most important, but it is methylated further by FaOMT (Fragariaxananassa O-methyltransferase) to 2,5-dimethyl-4-methoxy-3(2H)-furanone (DMMF) during the ripening process. It is shown here that transformation of strawberry with the FaOMT sequence in sense and antisense orientation, under the control of the cauliflower mosaic virus 35S promoter, resulted in a near total loss of DMMF, whereas the levels of the other volatiles remained unchanged. FaOMT repression also affected the ratio of feruloyl 1-O-ß-D-glucose and caffeoyl 1-O-ß-D-glucose, indicating a dual function of the enzyme in planta. Thus, FaOMT is involved in at least two different biochemical pathways in ripe strawberry fruit.

Key words: Fragariaxananassa, fruit ripening, O-methyltransferase, strawberry, volatiles
