Summary
PubMedWhy it matters This matters because duckweed grows explosively fast on water surfaces you've seen in ponds and lakes, and now that scientists can precisely edit its genes, it could soon be engineered to clean polluted water, produce food supplements, or even manufacture medicines — turning a common 'pond scum' into a green factory.
Duckweed is a tiny plant that floats on still water and grows incredibly fast, making it interesting for science and industry. Researchers figured out which variety of giant duckweed responds best to genetic modification and built a step-by-step process to reliably edit its DNA — including using the molecular 'scissors' tool called CRISPR. They also made the plant's genetic blueprint freely available online along with tools to help other scientists design their own experiments with it.

Scientists have developed a reliable method to genetically modify duckweed — the tiny floating plant that covers ponds — opening the door to using it as a powerful research tool and platform for producing medicines, biofuels, or other useful compounds.
Key Findings
Strain SP162 of giant duckweed was identified as the best candidate for genetic modification out of several screened genotypes, and its genome has been made publicly available (ID#: 5676).
The Agrobacterium-mediated transformation procedure was validated as robust and reproducible across multiple independent laboratories, enabling stable insertion of reporter genes and selectable markers.
S. polyrhiza SP162 showed a weak small RNA-based silencing response, allowing transgenes to remain active for prolonged periods in transient expression experiments — an advantage over many other plant systems.

Lemnoideae is a subfamily of flowering aquatic plants, known as duckweeds, water lentils, or water lenses. They float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands. Also known as bayroot, they arose from within the arum or aroid family (Araceae), so oft...
