4.2.3.B67	additional information	tissue-specific transcript abundance of GrTPS2 in leaves and flowers is accompanied by the presence of an endocyclic 7,13 double bond in (13E)-labda-7,13-dien-15-yl diphosphate. Spatial distribution of terpenoids in Grindelia robusta in extracts of roots, stems, leaves, flowers and resin from flower involucres via gas chromatography/mass spectrometry (GC/MS) analysis, tissue extract terpenoid profile, overview	
4.2.3.B67	root	despite a 60fold lower transcript abundance, GrTPS2 is also expressed in roots accompanied by the presence of trace amounts of grindelic acid, indicating that diterpenoid biosynthesis may also be active in roots of Grindelia robusta
