4.2.3.133	nutrition	tuber-specific over-expression of potato alpha-copaene synthase gene results in up to 15fold enhanced levels of alpha-copaene with a positive correlation between transgene expression level and alpha-copaene abundance. No aroma differences in the transgenic samples compared with controls and no significant differences in taste attributes are found. Sensory analysis suggests that alpha-copaene is not a major component of potato flavour	720634	
4.2.3.133	synthesis	expression in Saccharomyces cerevisiae leads to a titer of (-)-alpha-copaene of 9 mg/l at 48 h and around 7 mg/l in Escherichia coli, and the titer of (+)-delta-cadinene is 6 mg/l in Saccharomyces cerevisiae and 3.5 mg/l in Escherichia coli	720640
