Sugar Beet of the Future:
Die Zuckerrübe (Beta vulgaris L.) zählt zu den wichtigsten Ackerbaukulturen der gemäßigten Breiten und ist in Europa die bedeutendste heimische Zuckerquelle. Trockenstress ist die Hauptursache für nicht ausgeschöpftes Ertragspotenzial und wird sich im Zuge des Klimawandels voraussichtlich …

Promoter analysis in transgenic sugar beet
… purity / low environmental impact varieties of sugar beet. This requires modification of the phytohormone levels in the outer cambial rings of the storage roots. Control at the transcriptional level should provide the most efficient system for gene regulation since it will prevent the loss of …

The response of sugar beet (Beta vulgaris L.) to planting method and sowing date
… sowing date) were investigated on crops of sugar beet (Beta vulgaris L. cv. Amazon) during 1981/82 and 1982/83 seasons at Lincoln, Canterbury. In addition, the influence of transplanting at different growth stages (cotyledon, 2-leaf, 4-leaf) was also examined. Measurements of crop …

A molecular genetic analysis of resistance to poleroviruses in sugar beet and oilseed rape
Beet mild yellowing virus (BMYV) and Turnip yellows virus (TuYV) are both poleroviruses that cause significant reduction in the yields of sugar beet and oilseed rape respectively. Both viruses are transmitted by the aphid vector Myzus persicae. Current control methods rely heavily on the use of …

Hispanic Migration to Northeastern Colorado During the Nineteen Twenties: Influences of Sugar Beet Agriculture
<p>Growing beets to process into sugar was a large and important industry in 1920s Northeastern CO. The infrastructure to support the sugar beet industry was built and expanded in the first decades of the 1900s. Beyond infrastructure requirements the sugar beet industry relied on seasonal low …

Spectral Properties of Sugar Beet Canopy Related to Sugar Content and Quality of Beet Roots
… of crop yield is very important. However, for sugar beets, sugar content and other beet properties also directly affect economic benefits. This research investigated the relationship between the spectral characteristics of the sugar beet canopy in the visible and near-infrared bands and the …

Sucrose -Mediated Transcriptional Regulation of Proton /Sucrose Symporters in Source Leaves of Sugar Beet and Arabidopsis Thaliana
Taken together, the evidence supports the hypothesis that a sucrose-mediated regulatory pathway common to at least two plant families acts as a key step in regulating assimilate partitioning by modulating phloem loading in response to changing levels of sink demand. Also, symporters that are …

ECONOMIC AND STRATEGIC BEHAVIOUR IN DYNAMIC BUSINESS ENVIRONMENTS: THE CASE OF THE EX-SUGAR BEET FARMERS OF THE WEST MIDLANDS
… The model was applied to a sample of ex-sugar beet farmers in the West Midlands region of the UK to investigate the way in which these individuals adjusted to the Sugar Regime reform introduced on 20th February 2006. As a consequence of this reform, the sugar beet factory located in …

Molecular cloning, immunolocalization, and transgenic expression in yeast and tobacco of three cDNAs that encode sugar transporters in sugar beet
Sugar transporter genes from sugar beet have been cloned as a first step in understanding their contribution to assimilate partitioning. Two cloning strategies were attempted. One was functional complementation of a yeast mutant with a sugar beet cDNA library constructed in a yeast expression …

Regulation of taproot development and sucrose stabilization in sugar beet: Influence of invertase inhibitors and occurrence of mitochondrial energy-dissipating proteins
Die Zuckerrübe (Beta vulgaris) ist eine der wenigen Pflanzen, die große Mengen Saccharose speichert. Während der Entwicklung der Speicherwurzel akkumuliert Saccharose in den Vakuolen und kann in modernen Sorten einen Anteil von bis zu 20 % des Frischgewichtes erreichen. In der vorliegenden Arbeit …

A case of uncertainty in the vertical integration decision
… AT AUTHOR'S REQUEST.] Since the 1970s, sugar beet processors in the United States have undergone a shift from investor-owned firms to producer-owned firms. In 1970, all nine processors in operation were invest-owned, however, by the 1980s three producer-controlled firms had emerged. …

Isolation and characterization of the female sex pheromone of the sugar beet cyst nematode, heterodera schachtii, and an analysis of male precopulatory behaviour /
The sugar beet cyst nematode, Heterodera schachtii, is a major agricultural pest. The disruption of the mating behaviour of this plant parasite in the field may provide a means of biological control, and a subsequent increase in crop yield. The H. schachtii female sex pheromone, which attracts …

GENETIC MANIPULATION OF STORAGE ROOT DEVELOPMENT IN HORTICULTURAL CROPS
… kinase gene (Bvcrkl) has been isolated from sugar beet in the Norman Borlaug Institute laboratories. The expression of this gene is associated with dividing tissue, particularly the secondary vascular cambial rings of the sugar beet storage root. This gene is of interest for two reasons. As a …
