the enzyme is a member of the terpene synthase (TPS) superfamily, CsTPSFN TPS-b subfamily |

| 4.2.3.106 | evolution |
the taxa closely related to Mimulus lewisii have evolved several diff erent pollination syndromes, including hummingbird pollination and self pollination (autogamy), floral scent variation contributing to species diversification in this clade, E-beta-ocimene emission within this Mimulus clade does only occur in Mimulus lewisii, given the very low E-beta-ocimene emission in vivo, Mimulus parishii has a fully functional ocimene synthase enzyme in vitro, the other taxa do not emit E-beta- ocimene from flowers, overview |

| 4.2.3.106 | metabolism |
transcriptome analysis of trichomes of the cannabis hemp variety Finola reveal sequences of all stages of terpene biosynthesis. Nine cannabis terpene synthases (CsTPS) are identified in subfamilies TPS-a and TPS-b. Functional characterization identified mono- and sesqui-TPS, whose products collectively comprise most of the terpenes of Finola resin, including major compounds such as beta-myrcene, (E)-beta-ocimene, (-)-limonene, (+)-alpha-pinene, beta-caryophyllene, and alpha-humulene |

| 4.2.3.106 | physiological function |
differences in the relative emissions of (E)-beta-ocimene and (E,E)-alpha-farnesene from accession Wassilewskija, a high-(E)-beta-ocimene emitter, and accession Columbia, a trace-(E)-beta-ocimene emitter, are attributed to allelic variation of closely related, tandem-duplicated terpene synthase genes, TPS02 and TPS03. The Wassilewskija genome contains a functional allele of TPS02 but not of TPS03, while the opposite is the case for Columbia. Recombinant proteins of the functional Wassilewskija TPS02 and Columbia TPS03 genes both show (E)-beta-ocimene and (E,E)-alpha-farnesene synthase activities. Differential subcellular compartmentalization of the two enzymes in plastids and the cytosol is responsible for the ecotype-specific differences in (E)-beta-ocimene/(E,E)-alpha-farnesene emission |

| 4.2.3.106 | physiological function |
E-beta-ocimene, a monoterpene produced by ocimene synthase (OS) in Mimulus lewisii, is a floral scent important in attracting the species' bumblebee pollinators |
746701 |
| 4.2.3.106 | physiological function |
enzyme is involved in the herbivore-induced indirect defense response of spider mite-infested Lotus japonicus via de novo formation and emission (E)-beta-ocimene |

| 4.2.3.106 | physiological function |
floral scent of Jasminum sambac (Oleaceae) includes three major benzenoid esters: benzylacetate, methylbenzoate, and methylsalicylate, and three major terpene compounds viz. (E)-beta-ocimene, linalool and alpha-farnesene, analysis of concentrations and emission rates of benzenoids and terpenoids during the developmental stages of the flowers, overview |
