Main focus of investigations:
Regulation of photosynthesis, photosynthetic carbon metabolism and assimilate transport in relation to realization of plant productivity.
Areas of current interest:
- Study of the role of apoplastic invertase in the regulation of photosynthesis and assimilate transport under different conditions of plant mineral nutrition and illumination.
- Elucidation of the role of light in productivity of potato plants.
- Investigation of the nitric oxide participation in inhibition of photoassimilate export by nitrate.
Major results of investigations:
1. NO-signaling system was shown to be a probable mediator of nitrate in suppression of assimilates export from the leaf and rearrangement of metabolism under increased nitrate nutrition of plants.
2. Complex compounds (ammoniates) were designed and patented. These compounds, affecting the acid-base properties of the leaf extracellular medium, change apoplastic invertase activity and photosynthetic product export from leaves to sink organs. Treatment of plants with ammoniate solution enhances outflow of photosynthetic products from leaves to harvested plant parts and increases yields.
3. A hydroponic apparatus was devised and patented, allowing to obtain up to 30-40 healthy seed minitubers calibrated by size on test-tube potato plants propagated in vitro.
