The aroma biogenesis-related Olea europaea ALCOHOL DEHYDROGENASE gene is developmentally regulated in the fruits of two O. europaea L. cultivars

► A member of ADH gene family has been characterized in Olea europaea L. ► Gene expression has been monitored during fruit development in two cultivars. ► Volatiles, linked to ADH activity, were analysed by SPME and GC/MS in drupe paste. ► Both cultivar and developmental stage impact on ADH expression and aroma traits.
