Humans could not exist on Earth without the
crucial and unique contributions of plants.
Plant photosynthesis causes carbon dioxide
absorption, oxygen release, and synthesis of
soluble sugars. Plants also take up nitrate and
ammonium from the soil, assimilate them, and
biosynthesize various nitrogen-involving
compounds. This biomass production by plants is
increasingly important for the removal of carbon
dioxide from the atmosphere and for food
production.
The Laboratory of Plant Functional Biotechnology
is working to elucidate the molecular mechanisms
mediating the regulation of plant-specific
processes. One area of particular focus is the
transcriptional regulation associated with
biomass production.
We welcome students who are interested in plant
functional biology and the molecular mechanisms
regulating plant-specific processes.
