Biosynthesis, elicitation and roles of monocot terpenoid phytoalexins.
Recent advances in the discovery, biosynthesis, elicitation and functional characterization of monocot terpenoid phytoalexins are discussed, including conclusive evidence now exists for multiple plant receptors of fungal-derived chitin elicitors, phosphorylation of membrane-associated signaling complexes, activation of mitogen-activated protein kinase, involvement of phytohormone signals, and the existence of transcription factors.

A Tandem Array of ent-Kaurene Synthases in Maize with Roles in Gibberellin and More Specialized Metabolism1[OPEN]
It is reported that all three genes encode enzymes that are targeted to the plastid in planta, where diterpenoid biosynthesis is initiated, and which all readily catalyze the production of ent-kaurene. Expand
The application of synthetic biology to elucidation of plant mono-, sesqui-, and diterpenoid metabolism.
This review describes the emerging use of synthetic biology to recombinantly reconstitute plant terpenoid biosynthetic pathways in heterologous host organisms as a functional discovery tool, with a particular focus on incorporation of the historically problematic cytochrome P450 mono-oxygenases.

Functional Conservation of the Capacity for ent-Kaurene Biosynthesis and an Associated Operon in Certain Rhizobia
The scattered distribution of the operon via independent horizontal gene transfer within the symbiotic plasmid or genomic island shown here suggests that such diterpenoid production may modulate the interaction of these particular symbionts with their host plants. Expand
Molecular cloning and characterization of two tropinone reductases in Anisodus acutangulus and enhancement of tropane alkaloid production in AaTRI‐transformed hairy roots
Cl cloning and characterization of two fulllength cDNAs encoding TRI and TRII from the solanaceous plant Anisodus acutangulus by rapid amplification of cDNA ends show that AaTRI is a promising target for genetic engineering to increase tropane alkaloid in A. acUTangulus. Expand
Molecular characterization and expression analysis of two distinct putrescine N-methyltransferases from roots of Anisodus acutangulus.
Comparison of the deduced amino acid sequences of AaPMTs with those from tropane alkaloid-producing plants revealed that Aa PMTs had high similarity with other plants PMT, which indicated PMTs belonged to PMT superfamily. Expand
Three new steroid glycosides from the starfish Asterina pectinifera
Three new steroid glycosides, pectiniosides H–J (1–3), were isolated along with three known compounds (4–6) including a steroid glycoside and two polyhydroxysteroids, from the alcoholic extract ofExpand

Three new compounds, 4′-(4,5-dimethyl-1,3-dioxolan-2-yl)methyl-phenol (1), (3′-hydroxybutan-2′-yl)5-oxopyrrolidine-2-carboxylate (2), and atroviridetide (3), have been isolated from theExpand
Aromatic compounds from endophytic fungus Colletotrichum sp. L10 of Cephalotaxus hainanensis Li.
Six aromatic compounds were isolated from the endophytic fungus Colletotrichum sp. of Cephalotaxus hainanensis Li [Cephalotaxus mannii Hook. f.]. Their structures were determined on the basis ofExpand
Elucidation of gibberellin biosynthesis in bacteria reveals convergent evolution.
It is demonstrated that this operon encodes the enzymes necessary to produce GA9, thereby elucidating bacterial GA biosynthesis and revealing a central biochemical logic that is followed in all three convergently evolved GA biosynthetic pathways. Expand
