Plant terpene synthase genes (TPSs) have roles in diverse biological processes. Here, we report the functional characterization of one member of the soybean TPS gene family, which was designated GmAFS. Recombinant GmAFS produced in Escherichia coli catalysed the formation of a sesquiterpene (E,E)-α-farnesene. GmAFS is closely related to (E,E)-α-farnesene synthase gene from apple, both phylogene...

The possibility to utilize the antibacterial and antibiofilm potential of essential oils (EOs) in dentistry is recognized best seen design EO-based mouthwashes. up-to-date results, obtained with most commonly used formulation being consisted thymol, eucalyptol, menthol, methyl salicylate (Listerine), proved its efficacy against plaque gingival inflammation. However, novel alcohol-free products ...

The volatile composition of different apple varieties of Malus domestica Borkh. species from different geographic regions at Madeira Islands, namely Ponta do Pargo (PP), Porto Santo (PS), and Santo da Serra (SS) was established by headspace solid-phase microextraction (HS-SPME) procedure followed by GC-MS (GC-qMS) analysis. Significant parameters affecting sorption process such as fiber coating...

(E,E)-alpha-Farnesene was extracted as the main component of the volatile fraction of male Viscum album L. Male and female flowers of V. album L. growing on different host trees were analysed by solid phase microextraction and by lipophilic extraction.

The first step in the conversion of the isoprenoid intermediate, farnesyl diphosphate (FDP), to sesquiterpene phytoalexins in cotton (Gossypium barbadense) plants is catalyzed by delta-cadinene (CDN) synthase. CDN is the precursor of desoxyhemigossypol and hemigossypol defense sesquiterpenes. In this paper we have studied the mechanism for the cyclization of FDP and the putative intermediate, n...

Composition of the essential oil obtained from dried flowering aerial parts of Teucrium scordium L. (Labiatae) was analyzed by GC and GC/MS. Fifty-six components were identified in the essential oil of T. scordium. The major constituents of the oil were beta-caryophyllene (22.8%), (E)-beta-farnesene (10.4%), caryophyllene oxide (8.6%), 1,8-cineole (6.1%) and beta-eudesmol (5.1%).

the composition of the essential oils of teucrium chamaedrys l. belongs to the family lamiaceae, it is growing wild in the margin of mountainous roads of arid and cold climate of north iran. in this research, essential oils of teucrium chamaedrys l., extracted and measured at the different location by different methods of distillationand then were analyzed by gc and gc/ms. investigation and com...

Phenylacetonitrile, (E)-β-ocimene, linalool, (E)-4,8-dimethyl-1,3,7-nonatriene and (E,E)-α-farnesene were identified as Japanese beetle, Popillia japonica, feeding-induced volatiles from the leaves of the giant knotweed, Fallopia sachalinensis, but not by mechanical damage. Volatile emission was also induced by treatment with a cellular signaling molecule, methyl jasmonate. These results sugges...
