The impact of Terminal Inverted Repeat (TIR) transposable elements on plant genomes
<p>As major components in eukaryotic genomes, Transposable Elements (TEs) have been studied for decades. In the 1950s to 1990s, the predominant opinions considered TEs as “junk DNA” and “selfish elements”. However, subsequent studies showed that TEs are important players in genome dynamics. TEs are …

The use of the broad-host-range plasmid, pTF-FC2, in Agrobacterium tumefaciens mediated plant transformation
… This transfer system has revolutionized plant molecular biology to the extent that the introduction of foreign genes into plant genomes is now a basic technique. Apart from the finding that a defined segment (T-DNA) of the A. tumefaciens Ti plasmid can be transferred to plant DNA, the …

Využitie transgénnych rastlín pri štúdiu funkcie rastlinných génov
Use of transgenic plants in functional analysis of plant genes Functional genomics makes it possible to detect the functions of uncharacterized genes. It allows you to understand not only the functions of individual genes, but also the relationships between them. The acquired knowledge can also be …

Mechanisms and impact of alternative transposition-induced segmental duplications
<p>Segmental duplications are prevalent in both plant and animal genomes, and have played important roles in genome evolution. The focus of my project is to understand the transposition-mediated mechanisms that lead to the formation of segmental duplications, and the immediate impact of recently …

Supertree-like methods for genome-scale species tree estimation
… sequencing efforts, including the 5000 Insect Genomes Project, the 10000 Plant Genomes Project, the (~60000) Vertebrate Genomes Project, and the Earth BioGenome Project, which aims to assemble genomes (or at least genome-scale data) for 1.5 million eukaryotic species in the next ten years. To …

Production, characterisation and use of fluorescent markers in the study of plant nuclear envelope dynamics
… (NE) is one of the least studied membranes in plant cells. Genes encoding NE protein homologues are absent from currently available sequenced plant genomes. To produce a specific marker for the plant NE and in view of previous positive results with heterologously expressed proteins in plant …

Data Mining for Selected Genes of Agronomic Interest from the Oil Palm Genome Using a Comparative Genomics Approach
… to agronomic traits and transcription factors in plant genomes is essential to provide information on target genes for breeders. Taking advantage of the availability of completed genome sequences and the gene model available in a public database, the comparative genomic analysis of oil palm used …

Poly(A) Polymerase 1 (PAPS1) influences organ size and pathogen response in Arabidopsis thaliana
… polymerase (PAPS). Both vertebrate and higher-plant genomes encode more than one isoform of this enzyme, and these are coexpressed in different tissues. However, in neither case is it known whether the isoforms fulfill different functions or polyadenylate distinct subsets of pre-mRNAs. This …

Genetic strategies to manipulate meiotic recombination in Arabidopsis thaliana
… order to generate tools which may be useful for plant breeding. The first project sought to generate a second division restitution (SDR) population, where the second meiotic division is skipped. This is created by crossing an SDR mutant, omission of second division1, which produces diploid pollen …

Structural Biology of Cytochrome P450 Monooxygenases in Arabidopsis Thaliana Phenylpropanoid Pathway
Plant genomes are rich in cytochrome P450 monooxygenase sequences with 246 full-length genes found in the Arabidopsis thaliana genome. Unlike other enzymes that catalyze substrate modifications, P450s catalyze the activation of oxygen, which then reacts with the nearest substrate atom. Among the …

Evolution and Function of Receptor-like Kinases in Arbuscular Mycorrhizal Symbiosis
Evolution of the nutritional mutualism between plants and arbuscular mycorrhizal (AM) fungi was crucial to evolution of life, as it enabled the conquest of the green lineage and its ecosystem on land. Today, apart from AM fungi, plants co-exist with a plethora of micro-organisms, and exactly how …
