Biochemical, Molecular and Functional Analysis of Volatile Terpene Formation in Arabidopsis Roots
… of several volatile sesquiterpenes with (E)-β-farnesene as the major product. TPS22 and TPS25 are expressed in the root in distinct different cell type-specific patterns and both genes are induced by jasmonic acid. Unexpectedly, both TPS proteins are localized to mitochondria, demonstrating a …

Gamma and X-ray Irradiation Improve Postharvest Shelf-Life in 'Bartlett' Pears
… control pears, although concentrations of alpha-farnesene and conjugated trienes, considered precursors to superficial scald, were not affected. This research suggests that the formation of superficial scald can be influenced by factors other than alpha-farnesene and conjugated trienes. …

The Synthetic Biology of N2-Fixing Cyanobacteria for Photosynthetic Terpenoid Production
… linalool (C<sub>10</sub>H<sub>18</sub>O) and farnesene (C<sub>15</sub>H<sub>24</sub>). Chapter 1 is a review of literature in the field of biofuels and cyanobacteria, and chapter 2 is an introduction/list of objectives for the research in this dissertation. In chapter 3, we present the genetic …

Interazioni piante-insetti mediate da semiochimici
… α-copaene; β-cariofillene; α-cariofillene; α-farnesene), ha messo in luce come questo parassitoide risulti attratto solo dall’α-cariofillene, mentre l’α-farnesene sembra avere nei confronti dell’eulofide un effetto repellente.

Predation Risk and Colony Structure in the Pea Aphid, Acyrthosiphon Pisum
… When colonies detect an alarm signal, (E)-β-Farnesene (EBF), individuals drop off of the plant and disperse to "safer" feeding sites away from the natal leaf. When solitary pre-reproductive individuals detect EBF, their future offspring occupy "safer" feeding sites within the natal colony or …

Enhancing the Industrial Potential of Filamentous Cyanobacteria
… Anabaena sp. PCC 7120 with a 220% improvement in farnesene tolerance. To determine the optimal nitrogen source, dinitrogen (N2 gas) was compared to various fixed nitrogen sources. Ammonium chloride was determined to be the preferred nitrogen source for large scale cyanobacteria cultivation based …

Impact of Gamma Irradiation on Post-harvest Disorders in 'Bartlett' Pears
… compounds associated with superficial scald, α-farnesene and conjugated trienes, were lower in the irradiated pears, however, the incidence of superficial scald was higher in irradiated samples with 28 % and 32 % in 470 and 940 Gy treated pears, respectively, compared to 17 % in control pears, …

Environmentally Benign Extraction Processes in Analytical Separation of Essential Oils
… oxide B, matricine, dicycloether, and β-cis-farnesene. The optimal extraction conditions (temperature, pressure and time) for chamomile, rabbit brush, and skunk brush oils were (47 oC, 6620 psi, 45 min), (37 oC, 1720 psi, 43 min), and (35 oC, 3570 psi, 40 min) respectively. Selected major …

Exploring the genetic mechanisms underlying superficial scald development and prevention in apple fruit during postharvest storage.
… oxygen species (ROS) and the oxidation of alfa-farnesene, a sesquiterpene largely considered as a major actor in the onset of this disorder. Various postharvest treatments have been used to control the development of superficial scald in apple fruit, such as including the application of the …

Cell-type specificity and herbivore-induced responses of primary and terpene secondary metabolism in Arabidopsis roots
… production was also observed for the (E)-"-farnesene sesquiterpene synthase TPS25 when its expression was switched from the endodermis and non-hair producing epidermal cells to hair producing epidermal cells although only a weak fluorescent signal was detected from the expressed TPS25-mGFP …
