The Oligopeptide Transporters
The Oligopeptide Transporter gene family (OPT) encodes proteins that transport small peptides, peptides that bind metals, and modified peptides such as glutathione. We have discovered that several of these genes are active during germination and we are trying to elucidate what they are transporting and why. For more information on this gene family please see the review published in Molecular Plant in 2011 (Lubkowitz, 2011 The Oligopeptide Transporters: A Small Gene Family with a Diverse Group of Substrates and Functions?)

Carbohydrate Partitioning
This year the National Science Foundation awarded a five-year, $6.6 million dollar plant genome grant to a consortium from the University of Missouri, Purdue University, University of Florida, University of Nebraska, Saint Michael's College, and VT EPSCoR, to better our understanding of how CO2 captured in leaves through photosynthesis is distributed throughout the plant.  This process of distributing photosynthetic products throughout the plant is called carbohydrate partitioning and describes how carbohydrates move within plants from tissues where they are synthesized (source tissues) to regions where they are stored or consumed (sink tissues).  For example, generally, mature leaves are carbohydrate sources while flowers, fruits, seeds, and roots are typically sinks.   For more information on this project, please click the “NSF Research” link.
