protein does not contain the RRx8W motif,suggesting that the reaction mechanism does not proceed via an RR-dependent isomerization of geranyl diphosphate to 3S-linalyl diphosphate
deduced protein does not contain the RRx8W motif; member of a subfamily of the terpene synthase family designated the Tps-g group, which lacks the RRx8W motif; memeber of TPSg group of terpene synthases
; deduced protein contains a modification of the conserved RRx8W motif of plant monoterpene synthases. The N-terminal sequence indicates the presence of a plastid transit peptide
member oft the TPSb subfamily of angiosperm monoterpene synthases; the tandem arginine motif RRX8W is conserved in the deduced protein of TPS10; bifunctional myrcene/(E)-beta-ocimene synthase
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
products of Arabidopsis thaliana TPS10 are 56% beta-myrcene, 20% (E)-beta-ocimene, and less than 5% each of (+)-limonene, (-)-limonene, 2-carene, and tricyclene and an unknown monoterpene
(E)-b-ocimene is released from leaves of both undamaged and insect-damaged plants, but at levels two-fold higher in insect-damaged M.edicago truncatula
transcripts of LjEbOS are induced in plants infested with two-spotted spider mites, Tetranychus urticae, coinciding with increasing emissions of (E)-beta-ocimene as well as other volatiles, (Z)-3-hexenyl acetate and (E)-4,8-dimethyl-1,3,7-nonatriene, by the infested plants. Mechanical wounding of the leaves or application of alamethicin, a potent fungal elicitor of plant volatile emission, also induces transiently increased levels of transcripts, but not elevated release of (E)-beta-ocimene
when lima bean plants that have previously been placed downwind of transgenic tobacco plants that are constitutively overexpressing (E)-beta-ocimene synthase are infested by spider mites in an open-flow tunnel, they are more defensive to spider mites and more attractive to predatory mites, in comparison to the infested plants that have been placed downwind of wild-type tobacco plants. Similarly, when the transgenic tobacco-downwind maize plants are infested with Mythimna separata larvae, this results in reduced larval growth and greater attraction of parasitic wasps Cotesia kariyai. In a greenhouse experiment, lima bean plants placed near the transgenic tobacco plants are more attractive when damaged by spider mites, in comparison to the infested plants that have been placed near the wild-type plants. Volatile organic compounds emitted from infested receiver plants affect their conspecific neighboring plants to prime indirect defenses in response to herbivory
