Research Summary:

The major goal of our group is to develop new approaches for crop improvement using advanced methods of genetic engineering, molecular biology, and nanotechnology. We are working on understanding molecular bases for increasing the tolerance of plants to abiotic stress, enhancement of nutraceutical value of crops, regulation of plant size and biomass production, activation of seed germination, and plant growth.
