At present, consumers are concerned about the quality of fruit,
including nutritive value, aroma, colour, and shelf life. Colour and
aroma volatiles are two major quality attributes of tomato fruits.
AAT is capable of combining various alcohols and acyl CoAs,
resulting in the synthesis of a wide range of esters. Aliphatic esters
contribute to aroma of nearly all fruit and are emitted by vegetative
tissues (Schwab et al., 2008). ADH genes that are suspected to
participate in the production of aromas are expressed in a developmentally
regulated manner, particularly during fruit ripening
