Secrets of Duckweed Miniaturization

Researchers at the University of Nottingham have published a study in Current Biology on October 20, 2026, revealing how duckweed, one of the world's smallest flowering plants, manages to shrink to a body size of just a few millimeters without losing its original anatomical blueprint. Lead researcher Dr. Anthony Bishopp and co-author Dr. Alex Ware explained that rather than discarding organs or structures through extreme miniaturization, duckweed tightly compresses and fuses its essential shoot components into an incredibly compact body. This groundbreaking discovery challenges the long-standing biological assumption that extreme miniaturization in plants and animals inevitably involves the loss of core organs and structural body plans. Understanding this unique compact anatomy provides a crucial foundation for future agricultural cultivation, positioning duckweed as an untapped, highly efficient protein and food source for terrestrial consumption and long-duration space missions.
