Untersuchung der natürlichen Variation der Metalltoleranz von Arabidopsis thaliana Ökotypen und Identifikation von Genen verantwortlich für Toleranzunterschiede
… Variation in der Schwermetalltoleranz der Ackerschmalwand (Arabidopsis thaliana) genutzt werden um solche Komponenten zu identifizieren. Es wurden zink- und cadmiumtolerantere Ökotypen mit weniger toleranten verglichen und Gene identifiziert, die an der Ausprägung dieser Toleranz beteiligt …

Identification of growth-related tonoplast proteins in Arabidopsis thaliana
In a very simplified view, the plant leaf growth can be reduced to two processes, cell division and cell expansion, accompanied by expansion of their surrounding cell walls. The vacuole, as being the largest compartment of the plant cell, plays a major role in controlling the water balance of the …

Functional analysis of the sucrose synthase gene family in Arabidopsis thaliana
Sucrose synthase (Susy) is a key enzyme of sucrose metabolism, catalysing the reversible conversion of sucrose and UDP to UDP-glucose and fructose. Therefore, its activity, localization and function have been studied in various plant species. It has been shown that Susy can play a role in supplying …

Klonierung und Charakterisierung des PCC1-Gens ('Pathogen and circadian controlled 1')
Despite of a significant progress in understanding the defense signal transduction in plants, especially in Arabidopsis thaliana, there are still many open questions and new components to identify. A tool, to identify so far not characterized components of the signal-transduction-cascade is the …

Phosphatidylglycerophosphat-Synthasen aus Arabidopsis thaliana
Data base searches resulted in the identification of five A. thaliana genes encoding putative phosphatidyltransferases. Functional expression studies showed that the two genes AC01563 and AL35540 encode phosphatidylinositol synthases, while the gene AF118223.2 appeared to encode a cardiolipin …

Charakterisierung des GR1-Gens aus Arabidopsis thaliana (L.) Heynh. im Hinblick auf die rassenspezifische Resistenz des Ökotypen Wassilewskija gegenüber dem Peronospora parasitica-Isolat WELA
In this study the role of the GR1 gene in the race-specific resistance of the Arabidopsis ecotype Ws to the P. parasitica isolate WELA was investigated. In the susceptible gr1 mutant GR1 is tagged by a T-DNA insert and it was important to establish whether the mutant phenotype was indeed due to the …

Untersuchungen zur Funktion von Alb 3 im plastidären Proteintransport von Arabidopsis thaliana
Members of the Oxa1 protein family mediate the integration of proteins in their respective membranes. To the date, homologs within mitochondria (Oxa1p), E. coli (YidC) and chloroplasts (Alb3) have been investigated. Alb3 is the least investigated protein of this triple. A function within thylakoid …

Investigations on the role of mitogen-activated protein kinases 11 and 17 in defense response of Arabidopsis thaliana
Priming of defense for a stronger and faster response to abiotic and biotic stress is an important part of acquired immunity in plants and animals. Recent findings revealed the involvement of the two mitogen-activated protein kinases MPK3 and MPK6 in the regulation of priming in Arabidopsis …

Biochemische und molekularbiologische Untersuchungen zur Beteiligung reaktiver Sauerstoffspezies (ROS) am Wirkungsmechanismus der systemisch erworbenen Resistenz (SAR) in Arabidopsis thaliana (L.) Heynh
Systemic Acquired Resistance (SAR) can be conditioned in Arabidopsis by chemical and biological activators. This acquired resistance to a subsequent infection manifests itself as a phenocopy of the Hypersensitive Reaction (HR) and is correlated with an increased expression of so-called PR genes, …

Struktur und Funktion des GR1-Gens aus Arabidopsis thaliana (L.) Heynh
Arabidopsis thaliana shows race-specific interactions with the obligate biotrophic oomycete Hyaloperonospora parasitica. Thus, accession Wassilewskija (Ws-0) is resistant to the isolates WELA and NOCO. The gr1 mutant was isolated from a T-DNA population of Ws-0 plants showing susceptibility towards …

Untersuchungen zu Monolignolbiosynthese-Mutanten und den CCR Genen in Arabidopsis thaliana
Producing plants with reduced or suitably altered lignin are desirable industrial goals allow reduced energy input in paper mills and to obtain biomass that can be more efficiently fermented. Lignin is a water-insoluble complex phenolic polymer made up of condensed phenylpropanoid subunits. The …

Characterization of the cardiolipin synthase from arabidopsis thaliana
Cardiolipin (CL) is an anionic membrane phospholipid of a unique tetraacyl structure, consisting of two phosphatidyl moieties linked by a glycerol bridge. It constitutes the cytoplasmic membrane of eubacteria and represents the marker lipid of mitochondria in eukaryotes, where CL is predominantly …
