Scientific profile:

The  Department of Plant Molecular Physiology represents an interdisciplinary unit with its major scientific interests devoted to gene organization and function, characterization of active transport systems in higher plants, analysis of proteins and nucleic acids, bioinformatics and phytochemistry. Our major interest is in the identification and elucidation of the function of plant ABC-type proteins. This numerous transporters play an important role in modulation of plant environment interactions being a part of plant basal immune system implicated in the secretion of defensive/signaling secondary metabolites/molecules. We have performed a systematic search for genes coding putative ABC transporters in Medicago truncatula. At current state of art more than 30 genes coding the so called full size MtABCG transporters have been identified. We are conducting the functional analyses of selected Medicago ABCGs with molecular biology tools. Moreover  we are developing transformation facilities, in vitro protocols, and applying chromatography (HPLC, LC-MS) for metabolomic studies in order to understand the role of transport systems like ABC proteins in the distribution of plant natural products.

 

Current research activity

  • The profile of our research considers: (i) identification of new members of ABC family in Medicago truncatula, (ii) functional characterization of selected candidates, and (iii) study of the role of active transport systems in natural product distribution.

 

Most important research achievements:

  •  Systematic classification of the genes coding  ABCG transporters in model legume plant Medicago truncatula

Evidence that the full-size ABCG protein is involved in the translocation of early intermediates from the  phenylpropanoid biosynthetic pathway.

Presenting ABCGs as modulators of isoflavonoid levels in legumes during biotic stress.

  • LC/MS profiling of flavonoid glycoconjugates isolated from hairy roots, suspension root cell cultures and seedling roots of Medicago truncatula
