Phosphoenolpyruvat-Carboxylasen in Solanum tuberosum : Charakterisierung und Expression
… of a prefixing CO2 mechanism in the model plant Solanum tuberosum. A central role therein is the initial carboxylation reaction catalysed by the enzyme phosphoenolpyruvate-carboxylase (PEPC). This thesis presents research into increasing this enzyme’s activity in S.tuberosum. Two clones carrying …

Systematic studies in the genus Solanum in Africa
… of diversity in the large cosmopolitan genus Solanum. The genus is an important component of the African flora, and, with a variety of uses, many of the species have a significant interaction with man. The objective of the present study was an elucidation of some of the many taxonomic problems …

Biosynthesis of Steroidal Glycoakaloids in Solanum chacoense Bitter
… between SGAs and gene expression levels. Solanum chacoense, a wild potato species was used as a model plant from which tissues were harvested at specified developmental stages and analyzed for SGA content. The results from the SGA analysis suggest a qualitative and quantitative tissue- and …

A Discrete Density-Dependent Model of the Solanum Virus
<p>Compartmental modeling has been used to model infectious diseases for roughly 100 years. Since 2009, several papers have modeled zombie outbreak using this method with various results. This paper will develop a unique model for the spread of the <em>The Walking Dead</em> zombie virus throughout …

Characterization of activation tagged potato (Solanum tuberosum L.) mutants
Generation and characterization of activation tagged potato mutants could aid in functional genomic studies. Morphological and molecular studies were conducted to compare potato cv. Bintje, its two mutants, underperformer (up), and nikku generated using the activation tagging vector pSKI074, and …

Three genes from Solanum chacoense coding for squalene synthase
… deter feeding by potato pests. The wild potato Solanum chacoense accumulates higher amounts of SGAs than cultivated potato and some of its accessions produce leptines, a rare class of SGAs that is toxic to Colorado potato beetle. Unlike most eukaryotes, higher plants have more than one gene …

Phytohormonal regulation of Solanum lycopersicum development at the systems level
… across six major phytohormone classes from Solanum lycopersicum (tomato) fruit and leaf tissue. Chapter 3 describes phytohormone profiles of multiple tomato organs, including fruit, leaves, flowers, and roots, across their development. The phytohormone profiles developing fruit were further …

Investigation of multiple interspecific reproductive barriers in Solanum section Lycopersicon
… their integrity in nature. Wild tomato species (Solanum Section. Lycopersicon) are useful for studying IRBs. The monophyletic tomato clade includes 13 closely related species that possess a variety of mating systems and complex IRBs. IRBs can be classified according their operation during …

Genetic engineering for pest resistance in potato (Solanum tuberosum L.)
Insect pests of potato cause significant losses of yields under field and storage conditions. Conventional breeding techniques for targeting genes of interest is usually laborious and time-consuming. An alternative way for targeting genes of interest into the plant genome consists of …

The environmental physiology of tomato (Lycopersicon esculentum Mill. cv. Heinz-6004) and black or eastern black nightshade (Solanum nigrum L. and Solanum ptycanthum Dun.) competition
The growth of the black and eastern black nightshade was analyzed and predictive models were developed. Black and eastern black nightshade were planted on June 3, June 23, and July 12 in 1988 and May 28, June 17, and July 10 in 1989. All plantings were harvested 20, 40, and 60 days after planting, …

Expression rekombinanter pflanzlicher Phosphoenolpyruvat-Carboxylasen zur Beeinflussung des Kohlenstoffmetabolismus von Solanum tuberosum
… work was to regenerate transgenic C3-plants (Solanum tuberosum) with enhanced PEPC activity by overexpessing a altered endogenous PEPC. Therefore the ppc1 gene from Solanum tuberosum was modified, expressed in E. coli and analysed in vitro. By site-directed mutagenesis of the N-terminal …
