Use of TD-GC–TOF-MS to assess volatile composition during post-harvest storage in seven accessions of rocket salad (Eruca sativa). BELL L, SPADAFORA D.N. contributed equally to the work
No full textAn important step in breeding for nutritionally enhanced varieties is determining the effects of the postharvest
supply chain on phytochemicals and the changes in VOCs produced over time. TD-GC–TOF-MS
was used and a technique for the extraction of VOCs from the headspace using portable tubes is
described. Forty-two compounds were detected; 39 were identified by comparison to NIST libraries.
Thirty-five compounds had not been previously reported in Eruca sativa. Seven accessions were assessed
for changes in headspace VOCs over 7 days. Relative amounts of VOCs across 3 time points were significantly
different – isothiocyanate-containing molecules being abundant on ‘Day 0’. Each accession
showed differences in proportions/types of volatiles produced on each day. PCA revealed a separation
of VOC profiles according to the day of sampling. Changes in VOC profiles over time could provide a tool
for assessment of shelf life

Interactions between plant cell cycle genes and plant growth regulators. Expression of Spcdc25 and Wee1 in Arabidopsis alters the response of hypocotyl explants to auxin & cytokinin in culture
No full textExpression of Spcdc25 in Arabidopsis alters the response of hypocotyl explants to auxin & cytokinin in culture
No full textThe eukaryotic cell cycle comprises four distinct phases, mitosis (M), G1, DNA synthesis (S)-phase and G2 in which the key transitions are G1/S and G2/M. Progression of dividing cells through the cell cycle is controlled by key enzymes: cyclin-dependent kinases (CDKs), the products of cdc2-like genes. The regulation of CDK activity includes, amongst others, its activation by Cdc25 phosphatase at G2/M. This positive regulator is balanced by negative regulation by a protein kinase encoded by wee1. A plant homologue of the inactivating kinase, wee1, has already been cloned. However, a homologue of the activating phosphatase cdc25 has not been unequivocally identified in plants yet. The expression of cdc2-like genes can be influenced by many factors including plant growth regulators, mainly auxins and cytokinins. Expressing the fission yeast cdc25 (Spcdc25) in the tobacco BY2 cell line results in cells bypassing a cytokinin block, and in explants of tobacco expressing Spcdc25, shoot development is stimulated not only in a treatment that favours shoot formation (high cytokinin and low auxin) but also under root-stimulating conditions (high auxin and low cytokinin) and even without exogenous growth regulator treatment. Wild type Arabidopsis hypocotyls explants respond to increasing levels of cytokinin with rapid proliferation, greening and formation of shoots, but are unable to form shoots in the absence of auxin and cytokinin. We tested if hypocotyl explants from Arabidopsis transformed with constitutive and inducible lines Spcdc25 respond like wt to auxin (NAA) and cytokinin (Kinetin) in a system of grids in which we increase concentration of these exogenous plant growth regulators. We find that Wt and Spcdc25 hypocotiles segments are very sensible to higher liveles of ormons (1000 ngml-1 to 3000 ngml-1), calli grew with a lot of root hairs and the analysis of shots formation was impossible. Also is required a minimum level of NAA for calli induction in these strains: at 25 ngml-1 NAA/Kinetin we start to see grow of calli in Spcdc25 lines, plants in WT, not grow in not induced Spcdc25 line. Interesting results at 25, 50 ngml-1 NAA and 200ngml-1 Kinetin where in Spcdc25 there is grow of real roots, not visible in wt and not induced Spcdc25 line. At several concentrations of hormones Spcdc25 forms buds they will be show and discussed
Over expression of Spcdc25 and of ATWEE1 in Arabidopsis alter the sensitivity of hypocotyl explants to auxin and cytokinin in culture
No full textThe cell cycle is regulated by plant growth regulators (PGRs), mainly auxins and cytokinins. In eukaryotes, two genes regulate entry into mitosis: cdc25 and wee1, although a confirmed homologue of cdc25 in plants has not yet been identified. Expressing the fission yeast cdc25 (Spcdc25) in tobacco BY2 cells allows them to bypass a cytokinin block at G2/M. In tobacco and Arabidopsis roots, Spcdc25 expression led to an increased frequency of lateral roots. Conversely, over-expression of AtWEE1 in Arabidopsis induces a slower rate of root elongation and a reduced frequency of lateral roots. Wild type Arabidopsis hypocotyl explants respond to increasing levels of cytokinin with rapid proliferation, greening and formation of shoots, but are unable to form shoots in the absence of auxin and cytokinin. We tested if hypocotyl explants from Arabidopsis lines over-expressing ATWEE1 and Spcdc25 respond like WT to auxin (NAA) and cytokinin (Kinetin). We used a system of two-way grids in which we increased concentration of NAA and kinetin in X- and Y-axes, respectively. There were clear differences in the response between the transgenic and WT. All concentrations of auxin and cytokinin suppressed growth of calli in the AtWEE1OE line compared to WT. Moreover, in the AtWEE1OE, both organogenesis and formation of root hair structures were suppressed. At higher PGR levels neither WT nor Spcdc25 lines produced shoots but both produced roots and hairs. A minimum level of NAA was required for callus induction in both WT and Spcdc25 lines. However at low NAA/Kinetin there was growth of calli and more roots in Spcdc25 lines compared with WT. In an inducible Spcdc25 line plus inducer, roots formed at concentrations which suppressed roots in the inducible Spcdc25 line without inducer These results are discussed in the context of plant growth regulators and regulatory genes of the plant cell cycle

Title: American Journeys
Publisher: Vintage Books Australia
Author/s: Don Watson
In 1830 and 1831, as the facts about the New World increasingly challenged the myths about the New World, the French political theorist, Alexis de Tocqueville, journeyed across the nascent American democracy. Two hundred years after de Toqueville’s birth, a French philosopher and an Australian historian made their own journeys around the United States, recording observations and reflections. The trope of the stranger in a strange land shapes their observations and reflections upon the forms of American life that they encounter—yet while both ostensibly write about American society, the reader finds narratives of two very different Americas.

One day in the life of David Hicks
No full textDavid Hicks has just been cleared of the charges he faced in a US Military Commission, while imprisoned at Guantanamo Bay. His counsel, Michael Mori, has told the story of Hicks’ case: the problematic constitutionality of the military commissions and the charges laid under their authority; how Hicks was treated—and abused—by the military authorities; and the apparent indifference of the Howard Government to Hicks’ predicament. It’s a story that reveals and warns in equal measure …

Maslyuzhenko D.N. Turko-Mongol Traditions in the “State of Nomadic Uzbeks” of Abu al-Khair Khan
No full textThe author of this article identifies the daily and political traditions in the Khanate of Abu al-Khair, which researchers traditionally call the “State of nomadic Uzbeks”. This State was created in the south of Western Siberia in the 1430’s and annexed by military means to the land of Shiban’s (the younger brother of Batu) descendants. The overwhelming majority of researchers consider it as a Muslim State since its very foundation, substantiating their allegations by indication both on the reading of khutba in honor of Khan after he took the “throne of Sain Khan” and on the presence of the sheikhs and Sufis in his entourage.
At the same time, the authority of Abu al-Khair had the strong support of nomadic elite of more than twenty tribes. Precisely this elite, its inquiries and interests, which were advocated on the nobility councils, formed the existing political and daily traditions. These traditions reflect the preservation of Turko-Mongol customs among nomadic populations. We can find analogies of these practices in the earlier customs among the precursors of post-Golden Horde State, i.e., in the Mongol Empire and the ulus of Jochi. Traditions of the Abu al-Khair’s Khanate represented a phenomenon of cultural inertia, which were restored in the conditions of Islamization and could become the adats. This effect is particularly significant in view of the specific attitude of Sufi tariqats to the phenomena of social life.
In political terms, of particular importance among these was the restoration of the Toy and the related kurultay that could take place in accordance with the existing steppe (animals) calendar. The khans restored the ritual of robes and belts’ distribution as the main mechanism for redeployment of posts and responsibilities among the steppe aristocracy. Military tradition was also focused on samples of the previous time, which was particularly manifested in the selection of wings and avant-garde. In the course of military operations, there was the prevalent practice of magical rites known since the early Middle Ages and aimed at influencing the weather by means of the magic stone “yada” and Yadachi-sorcerers
