Most plant terpenoids are classified as secondary metabolites. A small portion of them are products of primary metabolism biosynthesized by relatively conserved pathways. Gibberellins (GAs), which are essential for plant growth and development, are diterpenoid phytohormones. (E,E,E)-Geranylgeranyl d...
