TAXONOMY
- We are curious to know what genes are
involved in plant-bacterium and bacteriophage-bacterium infection
processes and
how they determine the specificity of these interactions. Our modell
organisms are the symbiotic nitrogen fixing bacterium Sinorhizobium meliloti
and its bacteriophage 16-3
and the pathogen Agrobacterium
tumefaciens and A.
vitis bacteria.
- We are curious to know what is the genetic
background and the molecular mechanism of the Agrobacterium
resistance derived from Vitis
amurensis. We also aimed to construct Agrobacterium
resistant transgenic plants using gene silencing
techniques.
- We are also interested in molecular
taxonomy research by determining of mtDNA sequences to establish
phylogenic
relations of Hungarian Isophya
(Orthoptera,
Tettigoniidae) species
