Gene find could lead to healthier food, better biofuel production
Date:11/22/2010

expression patterns matched other genes involved in the formation of phenylalanine and volatile scent compounds in the flower.

To test the find, Dudareva and Maeda used the E. coli bacteria. They overexpressed the protein encoded by newly discovered gene and detected the expected enzyme activity. They also decreased the gene's expression in petunia flowers and witnessed a reduction in phenylalanine production.

"We provided both biochemical and genetic evidence that the gene is indeed involved in phenylalanine biosynthesis," Dudareva said. "It completes the pathway."

Dudareva said she would use the discovery to increase the scent of flowers in order to study the interaction of insects with flowers.
