Humans harvest grains primarily for the nutritional value of the endosperm, the placenta-like tissue inside the seeds of most flowering plants that nourishes the embryo. Tzung-Fu Hsieh, PhD, with the NC State University Plants for Human Health Institute (PHHI), is leading research to unravel the biological complexities surrounding endosperm development. In collaboration with Xu “Sirius” Li, PhD, a plant metabolic pathway engineer at PHHI, one aspect of his research is metabolomic profiling of seeds with larger endosperms. Hsieh foresees that his research will provide new insights into how scientists can impact seed size, nutritional value and other traits valued by farmers and consumers. Read the full story.
