Publication date: October 2018 Source:Biochemical Systematics and Ecology, Volume 80 Author(s): Zorica S. Mitić, Bojan K. Zlatković, Snežana Č. Jovanović, Jelena S. Nikolić, Biljana M. Nikolić, Gordana S. Stojanović, Petar D. Marin This is the first report on population differentiation based on composition of three different compound classes (n-alkanes, primary alcohols and diterpenes) in the epicuticular waxes of European black pine (Pinus nigra) from Balkan Peninsula and Southern Carpathians. The n-hexane extracts of 263 samples, originating from 15 native populations of four P. nigra subspecies (nigra, dalmatic...

New chemical data on the ant Myrmecina graminicola (Formicidae, Myrmicinae): Unusual abundance of alkene hydrocarbons and esters
Publication date: October 2018 Source:Biochemical Systematics and Ecology, Volume 80 Author(s): Alain Lenoir, Alix Khalil, Nicolas Châline, Abraham Hefetz We investigated the possible origin of the specific odor of the terricolous ant Myrmecina graminicola by elucidating its pattern of volatiles. It appeared to have a very large hypertrophied poison gland reservoir, which contains copious amounts of acetate and propionate esters that are also present on the cuticule. The poison gland was previously reported as the source of sex pheromone, but the finding that queens and workers exhibited the same ester patterns tend...

Chemical constituents of Anthospermum perrieri (Rubiaceae)
Publication date: October 2018 Source:Biochemical Systematics and Ecology, Volume 80 Author(s): Tiana Sylvia Ralambonirina Rasoarivelo, Raphaël Grougnet, Sylvie Michel, Christiane Rakotobe Guillou, Brigitte Deguin Phytochemical investigation on the aerial parts and roots of Anthospermum perrieri led to the isolation of two anthraquinones (1-2), one naphthohydroquinone glycoside (3), four flavonoids (4–7), two coumarins (8–9), two phenolic acids (10–11), two iridoids (12–13) and one steroid (14). Flavonoids (4–6), phenolic acids (10–11), steroid (14), asperuloside (12) were identifi...

Phenotypic variation of wild Chamomile (Matricaria chamomilla L.) populations and their evaluation for medicinally important essential oil
In this study the existing phenotypic and chemotypic variability of native to Greece chamomile populations was investigated, aiming to select the appropriate ones for the production of high quality essential oil. For this purpose, eleven native chamomile populations were studied concerning the main constituents of the essential oil (a-bisabolol and chamazulene), and a pre-breeding evaluation experiment was initiated, setting up as main target the essential oil composition and agronomical traits. The two most remarkable populations were further assessed, in comparison to five commercial chamomile varieties, through a honeyc...

DOXC-class 2-oxoglutarate-dependent dioxygenase in safflower: Gene characterization, transcript abundance, and correlation with flavonoids
Publication date: October 2018 Source:Biochemical Systematics and Ecology, Volume 80 Author(s): Yanhua Tu, Dongqiao Li, Lijiao Fan, Xinlei Jia, Dandan Guo, Hailiang Xin, Meili Guo DOXC is one of the 2-oxoglutarate-dependent dioxygenases (2OGDs) classes, which is involved in the biosynthesis of colorful flavonoids and plant hormones. Safflower (Carthamus tinctorius L.) is a commonly used plant with flavonoids. Herein, we focused on analyzing the characterization, transcript abundance, and correlation of DOXC-class 2OGDs in safflower with flavonoids for the first time. TBLASTN analysis showed that they were implicated in th...

Comparative proteomic analysis reveals the adaptation of Herpetospermum pedunculosum to an altitudinal gradient in the Tibetan Plateau
In this study, we used proteomic technologies to study the tolerance mechanism of H. pedunculosum to high altitudes, namely, 2800 m, 3000 m, 3100 m and 3300 m. A total of 52 proteins were successfully identified and classified into eleven groups based on their molecular functions, i.e., cytoskeleton dynamics (3), energy (5), carbohydrate metabolism (9), photosynthesis (11), protease (2), transcription (5), stress and defense (6), molecular chaperones (3), protein synthesis (2), other materials metabolism (2) and unknown function (4). These results indicated that the chloroplast pathway as well as the production of ...
