On Tuesday, July 28, 2026, Samantha Nuzzi, a Ph.D. candidate at the Danforth Plant Science Center, presented a tobacco plant with disrupted chlorophyll production. This specific biological modification caused the plant to lose its characteristic green color. The research conducted by Nuzzi focuses on studying intercellular plant mechanisms. The demonstration highlights the effects of chlorophyll disruption on plant pigmentation and the ongoing scientific investigations into plant cellular functions at the Danforth Plant Science Center.
