Plant molecular biology:
Development of gene silencing techniques: double-stranded RNA produced by bacteria and inducing silencing with promoters of snRNA genes in different species (Arabidopsis, grapevine, maize).
Physiological and molecular background of Beta-aminobutyric acid induced resistance and priming in Arabidopsis and grapevine.
The role of lipid-derived signal molecules in the emergence of priming. Molecular research of induced resistance in grapevine. Partnership: Brigitte Mauch-Mani; University of Neuchatel, Switzerland.
Abiotic stress responses:
Changes in flavonoid composition and gene expression during adaptive responses to solar irradiance (visible and UV) in various autochthonous grapevine cultivars.
Plant anatomy and histology:
Characterisation of plant leaf anatomy (grapevine cultivars) to reveal changes in histological parameters influenced by the environment (light).
Methods: sectioning wiht rotary microtome, light microscopy
OTKA K101430; UP, Medical School, Department of Pharmacognosy.
Phenolic-fingerprinting of plants (grapevine cultivars), localisation of flavonoids, their role in plant life.
Methods: thin layer chromatography, HPLC, fluorscence and laser scanning microscopy
OTKA K101430; Corvinus University of Budapest; Biological Research Centre Szeged.
Leaf antioxidant – pro-oxidant studies:
Acclimation to UV-B (280-315 nm) radiation in controlled environment and filed studies. UV-inducible changes in the antioxidant – pro-oxidant balance.
In collaboration with: Örebro University (SE), Maynooth University (IE), University College Cork (IE).
Gas exchange performance and acclimation of the regrowth:
Functional ecological response of woody saplings (e.g. beech, hornbeam, oak, ash, other invasive species) are studied related with forest regeneration. Field (instantaneous) and climate controlled (steady-state) measurements are designed by the main abiotic factors (carbon-dioxide, light, temperature, humidity). TÁMOP-4.2.2.A-11/1/KONV-2012-0004.
Phylogenetic relationships in the Neotropical tribe Hamelieae (Rubiaceae, Cinchonoideae) and comments on its generic limits. Morphological and genetic examinations of Ranunculus (subg. Batrachium DC. (A. Gray) populations in the Carpathian Basin.
Molecular phylogenetics of genus Ceratophyllum.
Sequence analysis of nuclear and chloroplast regions. Selecting DNA substitution models using MrModeltest. Bayesian analysis of molecular evolution using MrBayes, Maximum Parsimony, Maximum likelihood, Bootstrap (PAUP).
Analysis of genetic and ecological segregation of the invasive Solidago gigantea in the native and non-native range.
Selection and analysis of species specific microsatellite markers. Determination of ploidy level in Solidago gigantea by flow cytometry.
