  Background: How the distribution and sequestered form of plant macro/micro-nutrients influence their bioavailability, and ultimately impact human health, are poorly understood. The legume Medicago truncatula has a portion of its tissue calcium (Ca) sequestered in the form of the Ca oxalate (CaOx) crystal which reduces its nutritional value in terms of Ca bioavailability. The calcium oxalate deficient 5 (cod5) mutant has a total Ca content similar to wild-type (WT) plants, but sequesters less of its tissue Ca in the form of the CaOx crystal. Previous short-term mice feeding studies suggest that this difference is responsible for the improved Ca bioavailability of the cod5 plants compared to WT plants. Objectives: To perform long term feeding studies with Vitamin D Receptor Knockout (VDR-KO) mice and the nutritionally improved cod5 line to assess the .. View More»
