Laboratory of Plant Genetic Engineering and Cell Genetics

Dr. Márton's main research objective has been genetic manipulation of plants by cellular and molecular techniques. Phytoremediation/biomass improvement research has become the major long term commitment of his laboratory. Development of micropropagation/genetic engineering technologies of environmentally important/potential new crop plants such as cordgrasses, reed, cattails, rushes, sedges and the giant reed are in progress. His transgenic plant systems are based on the Agrobacterium mediated gene transfer technology, that he pioneered to develop and in some cases different direct gene transfer techniques are also used, such as chemical, electroporation and DNA gun technologies. For the above monocot plant transformation Agrobacterium vectors have been constructed for altering heavy metal processing patterns (sequesterization, accumulation) and for Hg volatilization as well as for enabling plants to degrade different halogenated organic wastes. The dehalogenation project is becoming a multi-disciplinary effort which involves the combination of protein engineering with genetic engineering technologies. His present interest areas include: physiological aspects of tissue cultures, expression of transgenes, mechanism/ control of gene silencing, and epigenetic regulation of gene expression in plants. In the biotechnological applications, such as development of large scale micropropagation technologies and tissue culture based molecular breeding of new elit lines his major collaboration partner is the Southern Sun Biosystems Inc. http://www.sosun.com/.
