We analyzed the genetic diversity of 531 Sinorhizobium meliloti strains isolated from nodules of Medicago sativa cultivars in two different Italian soils during 4 years of plant growth. The isolates were analyzed for DNA polymorphism with the random amplified polymorphic DNA method. The populations showed a high level of genetic polymorphism distributed throughout all the isolates, with 440 dif...

Cultivar identification is a key step to avoid the formation of homonyms and synonyms of Ginkgo biloba. In this study, a new approach based on combinational utilization of polymorphic bands produced from 6 different random amplified polymorphic DNA (RAPD) primers was developed for identifying 42 Ginkgo cultivars, and a manual cultivar identification diagram that consisted of polymorphic ba...

Quantities of free amino acids in segments of cotton roots resistant and susceptible to Meloidogyne incognita were compared. Following infection, the root-knot susceptible cultivar, M8, had greater percentage increases of certain individual free amino acids than the resistant cultivar, Clevewilt, but the sum total of free amino acids was greatest in the resistant cultivar. More free amino acids...

The path planning problem is relevant for all applications in which a mobil robot should autonomously navigate. Finding the shortest path in an environment that is only partialy known and changing is a difficult problem. Replaning the entire path when the robot encounters new obstacles is computational inefficient. Starting with an initial path and than modify the path locally does not guarante...

Mobile Endgeräte werden vermehrt in Lernszenarien außerhalb des Klassenzimmers eingesetzt. Häufig werden dazu spezialisierte Anwendungen genutzt, die i.W. ein bestimmtes Lernszenario unterstützen oder Expertenwissen bei der Autorierung benötigen. Ziel von Mobilogue ist es ein flexibles, aber einfaches Autorenwerkzeug zur Erstellung unterschiedlicher Lehr-Lern-Szenarien zur Nutzung auf mobilen E...

Mobil merupakan kendaraan roda empat yang sangat nyaman, dibalik kenyamanan tersebut terdapat senyawa berbahaya di hasilkan dari emisi tidak sempurna mesin (vehicle). Dalam gas sejumlah unsur kimia seperti Air (H2O), Karbon Monoksida (CO), Dioksida (CO2), Nitrogen Oksida (NOx) dan Hidro (HC). kajian ini fokus dalam pengujian CO, CO mempunyai ciri berwarna, berbau, mudah terbakar, larut air hasi...

Time-courses of the development of freezing tolerance and the expression of a cold-responsive gene wlt10 were monitored during cold acclimation in wheat (Triticum aestivum L.). Bioassay showed that cold acclimation conferred much higher freezing tolerance on a winter cultivar than a spring cultivar. Northern blot analysis showed that the expression of wlt10 encoding a novel wheat member of a ce...

Research was conducted to quantify the development of the corn earworm (= bollworm), Helicoverpa zea (Boddie), on two different transgenic cotton cultivars (DP 50B and NuCOTN 33B) that contained different levels of the Cry1Ac endotoxin from the soil bacterium, Bacillus thuringiensis Berliner. Using a field cage, an inverse relationship between the amount of Cry1Ac among cultivars versus the wei...

BACKGROUND In this study, we assessed the actively metabolizing bacteria in the rhizosphere of potato using two potato cultivars, i.e. the genetically-modified (GM) cultivar Modena (having tubers with altered starch content) and the near-isogenic non-GM cultivar Karnico. To achieve our aims, we pulse-labelled plants at EC90 stage with (13)C-CO2 and analysed their rhizosphere microbial communiti...
