Project Inaugural Meeting Szeged, 2-3 February,
2011
2
General objectives The interactive effects of
abiotic, biotic and genetic factors on the
performance of wheat, maize and alfalfa plants
and yield components that may influence nutrient
quality and safety

• The two sides of the micronutrient availability
  (deficiency and excess)
• ii) The presence of microbial toxins due to
  microbial (fungal and/or bacterial) infections
  and their effects on the microelement
  accumulation (effects of toxins on channel
  activity)
• iii) Toxins and physiological/metabolic
  processes
• iv) The effects of genomic background on
  micronutrient accumulation and distribution.

and Development
1. Procuration of equipments 2-7/2011 Szeged, Timisoara

Procuration of equipments is planned in both localities to improve infrastucture. In Szeged, an inductively coupled plasma mass spectrometer (ICP-MS) is planned for the multielement analysis of microelements in environmnetal, food and feed plant samples in the region of mg/kg to pg/kg. In Timisora, the purchase of a Bioanalyzer, a UV-VIS Spectophotometer and a cooling centrifuge are necessary to improve molecular biological work.
2. Determination of microelements as affected by microbial infection or heavy metals presence . 7/2011 5/2012 Szeged, Timisoara
These will be determined in 2 wheat cultivars, 2 corn genotypes (GM and conventional) and alfalfa cultivars of different susceptibilities. Microelements will be determined in Szeged, microbial presence and toxins in Timisoara.
3. Determination of antioxidant defence mechanisms as influenced by microbial toxins 7/2011 5/2012 Szeged
The catalase, superoxide dismutase, peroxidase , glutathione S-transferase activities will be determined in the same biologicical material. In addition, glutamine syntethase iso-enzymes and Rubisco levels will be determined by 2D gel chromatography. These will be carried out in Szeged.
4. Effects of genomic background on essential and toxic microelements 7/2011 5/2012 Szeged, Timisoara
This subactivity is based on earlier results we have shown out significantly different levels of Fe, Zn, Cu and Mn in wild, ancient and cultivated wheat species in the genera Triticum and Aegilops. Alfalfa (Medicago sativa) cultivars also show different phytoremediation potential for both inorganic and organic pollutants. Besides the analysis of wheat and alfalfa cultivars, investigation for their membrane-transport mechanisms and photosynthetic activities will also be carried out.
