Professional Statement
My research program seeks to understand how and why organisms’ biosynthesize oxalate, catabolize oxalate, and form crystals of calcium oxalate. In plant foods, oxalate exists in two general forms, soluble and insoluble, and each form can have a negative impact on the health of the person consuming the plant food. In the soluble form, oxalate can be absorbed directly from the diet and contribute to the pathological condition of renal stone formation. In the insoluble form, oxalate acts as an antinutrient by binding to certain minerals (e.g., calcium) and rendering the bound mineral unavailable for nutritional absorption. Given the impact of oxalate on human health as well as the important roles for oxalate in the growth and development of the plant (e.g., resistance to environmental stress), a more comprehensive understanding of plant oxalates is desired.
Our current focus is to decipher the pathways of calcium oxalate crystal formation and oxalate degradation in plants. To accomplish this goal, we are taking an integrated approach by combining methodologies from genetics, genomics, biochemistry, and cellular biology to identify and characterize the genes and proteins that make up these pathways. Such studies will not only broaden our fundamental understanding of the mechanisms controlling the formation of the calcium oxalate biomineral, but will confer the ability to deconstruct and reconstruct this biomineralization process in selected crops. This ability will allow us to rationally design strategies aimed at improving the nutritional quality (e.g., calcium bioavailability) and production (e.g., insect resistance) of plant foods.
