Rhizosphere bioremediation of polychlorinated biphenyls (PCBs) offers a potentially inexpensive approach to remediating contaminated soils that is particularly attractive in remote regions including the Arctic. We assessed the abilities of two tree species native to Alaska, Salix alaxensis (felt-leaf willow) and Picea glauca (white spruce), to promote microbial biodegradation of PCBs via the re...
We summarized the status of wolves (Canis lupus), elk (Cervis elaphus), and woody browse conditions during the 20th century for the upper Gallatin elk winter range in southwestern Montana, USA. During this period, wolves were present until about the mid-1920s, absent for seven decades, and then returned to the basin in 1996. A chronosequence of photographs, historical reports, and studies indic...
Tempranillo is one of the most widely cultivated grapevine varieties in Spain. After several years of clone selection, some highly recommended old clones have been identified in terms of both their qualitative and production characteristics. This study was designed to discriminate among 28 ancient clones of the cultivar Tempranillo (Vitis vinifera). DNA samples from clones were analysed using t...
the purpose of this study was to compare rooting methods in tissue culture regenerated-clones in sugar beet and their adaptation to environmental conditions and determine clones ploidy stability. two kinds of explants including shoot apex of seedlings and inflorescence stem pieces were used for preparation and propagation of the clones in media. in the next step, three rooting and adaptation me...
increasing of wood demand is currently one of the most important problems in our society. different clones of populus nigra from salicacea as a native fast-growing species have a good potential for planting in wide scale. but because of the ecological differences in the field, especially. temperature alterations, segregation of the cold resistant clones in relation to in seedling stage establis...
conclusions dlec1 suppresses tumor cell growth the presence of ap-2α2 and stimulates cell proliferation in the down-regulation of ap-2α2 in dlec1 over-expression stable clones of htc116. results the dlec1 over-expression was found to reduce the number of colonies in colony formation and to induce g1 arrest in seven clones, and apoptosis in one clone in the cell cycle analysis. furthermore, rega...
Our study investigated the accumulation of chromium, nickel, lead and cadmium by maize (Zea mays L.), sunflower (Helianthus annuus L.), willow (Salix x smithiana Willd.), and poplar (Populus nigra L. x P. maximowiczii), and the realtionship between the contaminants in soil and in plants. The experiment was performed in contaminated soil (former waste incineration plant) at the Hradec Králové (C...
