Transport Processes
Dr.
Tegeder’s work deals with identification, characterization,
and molecular genetic manipulation of key transport processes
controlling partitioning of nutrients, e.g., amino acids
and sugars in plant organs. These transport processes
are control points in plant reproductive success/production
and nutritional quality of seeds and other edible plant
parts. Her most recent work uses a combination of molecular,
biochemical, cell biological, physiological, and genetic
tools to understand mechanisms regulating amino acid
transport into sink organs such as developing reproductive
structures and seeds. She has cloned and characterized
a number of amino acid transporters and is expanding
her work to a broad range of transporters from different
nutrient transporter families. These genes are being
used to manipulate transport patterns and efficiency
by molecular genetic techniques. While Arabidopsis has
served as a model system, she has extended her efforts
into the engineering of legumes for improved productivity
and nutritional quality. These
approaches are critical to the emerging field of “nutragenomics,” which
is the targeted identification of factors required for
nutritional quality and molecular genetic applications
of the information obtained. Results from her transporter
work, as well as some recent reviews of the topic, have
been published in the top journals in the plant sciences
and have been well cited.
