abstract

  • Summary Plants can synthesize the aromatic amino acid Phe via arogenate, but it is still not known whether they also use an alternative route for Phe biosynthesis via phenylpyruvate, like many micro-organisms. To examine this possibility, we expressed a bacterial bi- functional PheA (chorismate mutase/prephenate dehydratase) gene in Arabidopsis thaliana that converts chorismate via prephenate into phenylpyruvate. The PheA-expressing plants showed a large increase in the level of Phe, implying that they can convert …
