DENTON (UNT), Texas - Arabidopsis thaliana is a seed so tiny that it can fit into Abraham Lincoln's eye on a penny. Its small size, rapid life cycle and ability to produce thousands of seeds make this plant perfect for research. Now scientists who use it for studies have a new advantage. Drew Sturtevant, a student from the University of North Texas, was just able to complete 3D imaging of the inside of this tiny seed that reveals its chemical mapping for the first time. His breakthrough was recently published in the journal BBA Molecular and Cell Biology of Lipids.
