Molecular and biochemical studies were undertaken to elucidate gene/product relationships which influence key fruit quality traits in cultivated strawberry (Fragaria × ananassa Duch.). Comparative transcription profiling experiments in selected genotypes pointed out a number of differentially- expressed genes, possibly related to important fruit quality traits as aroma and fruit firmness. Some of the altered cDNAs encode putative cinnamyl alcohol dehydrogenase, cinnamoyl CoA reductase, cellulase and expansin genes, involved in the early steps of lignin biosynthesis and in cell wall structure, respectively. Parallel biochemical analyses studied the spectra of volatile compounds by Proton Transfer Reaction-Mass Spectrometry (PTR-MS) and alcohol acyl transferase (AAT) specific activity in red fruits. A correlation between the expression of an aat gene, total AAT activity and the presence of related esters in fruit headspace was found. © Springer Science+Business Media B.V. 2006.
