The image is showing a 2D rendering of both three-dimensional (3D) images of Velvet leaf (Abutilon theophrasti) intact seeds (~ 2-4 mm in diameter, inset) and a single 2D virtual section collected from the UIUC Agricultural Fields in Urbana, IL. It is an invasive species that is considered a damaging weed to agricultural crops, such as corn and soybeans. The images are acquired by the X-5000 micro CT system and rendered in NSI CT software at the Carl R. Woese Institute for Genomic Biology Core Facility.
