Brassicaceous plants are characterized by a pronounced metabolic flux toward sinapate, produced by the shikimate/ phenylpropanoid pathway, which is converted into a broad spectrum of O-ester conjugates.

Tests have shown that plants produce
sinapate esters and send them to the outer layer of their leaves to protect themselves.
In flowers and seeds, F5H is required for the production of sinapate esters, which are intermediates of syringyl lignin biosynthesis in higher plants, and some of them serve as precursors for important secondary metabolites [32].

In particular, the invention relates to the inhibition of the enzymatic activity of a UDP-glucose:
sinapate glucosyltransferase (SGT) in transgenic plant cells.
