Volatile esters are the chems. that have multiple physiol. functions including plant defense responses and reproduction From a human perspective, the esters largely contribute to the fruity aroma of freshy fruits. Composition of volatile esters show a significant diversity among the wild tomato species (Solanum sect. Lycopersicon). To address the basis for this divergence, here we conducted functional anal. of a gene encoding major alc. o-acyltransferase (AAT1) that catalyzes volatile ester formation. Although AAT1 transcripts were highly expressed in the ripe fruits of all the wild species examined, their enzymic properties significantly differed due to amino acid sequence variations. Notably, AAT1s from S. pennellii showed the highest ability to produce acetate esters whereas AAT1s from S. neorickii, S. chmielewskii and S. habrochaites had the lowest activities. Further, screenings using domain-swapped or point-mutated AAT1s allowed us to identify Met/Thr352 as one of the critical residues related to the transferase activity with acetyl-CoA. This finding is potentially applied to aroma engineering in which a site-directed mutagenesis at this position in alc. o-acyltransferases could enable to manipulate volatile ester levels in ripe fruits.
