... synthases of non-flowering and flowering plants suggests that monofunctional diterpene cyclases involved in ent -kaurene biosynthesis may have co-evolved with gibberellin biosynthesis. cyclase ent -kaurene gibberellin phytoalexin Selaginella moellendorffii substrate specificity...

... diterpenoid biosynthesis, we characterized CYPs that catalyse alternative hydroxylation of ent -sandaracopimaradiene, the precursor to the rice oryzalexin antibiotic phytoalexins. In particular, CYP76M5, CYP76M6 and CYP76M8 were all shown to carry out C-7β hydroxylation, whereas CYP701A8 catalyses C-3α...

... members GSTF2 and GSTF3 bound a series of heterocyclic compounds, including lumichrome, harmane, norharmane and indole-3-aldehyde. When screened against total metabolite extracts from A. thaliana , GSTF2 also selectively bound the indole-derived phytoalexin camalexin, as well as the flavonol quercetin-3...
