|Syn-copalyl diphosphate synthase.|
|Geranylgeranyl diphosphate <=> 9-alpha-copalyl diphosphate|
- This class II terpene synthase produces syn-copalyl diphosphate,
a precursor of several rice phytoalexins, including oryzalexin S and
momilactones A and B.
- Phytoalexins are diterpenoid secondary metabolites that are involved
in the defense mechanism of the plant, and are produced in response
to pathogen attack through the perception of elicitor signal
molecules such as chitin oligosaccharide, or after exposure to UV
- Constitutively expressed in the roots of plants where one of its
products, momilactone B, acts as an allelochemical (a molecule
released into the environment to suppress the growth of neighboring
- In other tissues the enzyme is up-regulated by conditions that
stimulate the biosynthesis of phytoalexins.
