University of Nottingham researchers map how duckweed packs a full plant body into a few millimetres
The study shows duckweed compresses and fuses plant parts rather than losing them, opening new avenues for food research and space‑mission crops.

Researchers at the University of Nottingham have detailed how duckweed, one of the world’s smallest flowering plants, maintains the essential architecture of larger plant shoots within a body only a few millimetres across, according to a report published on scitechdaily.com on 20 October 2026.
What happened
The team used advanced microscopy and gene‑expression analysis to examine duckweed fronds that float on freshwater surfaces. Their observations revealed that, unlike the organ loss seen in many miniaturised animals, duckweed’s shoot components are tightly compressed and fused, preserving the basic plant blueprint in a remarkably compact form.
What the reports add
Scitechdaily noted that the findings were published in the journal Current Biology, highlighting a challenge to the assumption that extreme miniaturisation necessarily involves losing structural parts. The outlet also emphasized the broader interest in duckweed as a potential future food source, both on Earth and for space missions, because of its rapid growth and high protein content.
What was said
Dr Anthony Bishopp, who led the research, told scitechdaily, “We were interested to find out how a complete plant body plan can be packed into such a tiny space… duckweed appears to have compressed and fused its components into an incredibly compact plant.” Co‑author Dr Alex Ware added, “Duckweeds are astonishingly small, so it is tempting to think of the…”.
How it came about
Duckweed’s unusual anatomy has long been poorly understood, limiting its cultivation as a food crop. The new study provides a structural foundation that could guide future efforts to improve duckweed for protein production, linking to Felo’s earlier coverage of small‑scale biological innovations such as the digitised vaquita skeleton.
