Brazilian sedge reproduces sexually but without DNA reshuffling, producing genetic clones
Sep 16, 2026
Sexual reproduction usually reshuffles genetic information, creating offspring that differ from their parents. But one small plant takes an unexpected route. In a new study published in Nature, an international team led by André Marques at the Max Planck Institute for Plant Breeding Research in Col
ogne has shown that the Brazilian beak-sedge Rhynchospora tenuis reproduces sexually—producing pollen, fertilizing its egg cells and setting seeds—but has completely lost the reshuffling of DNA between chromosomes from each parent. The offspring retained the same genetic makeup as their mothers, effectively mimicking clonal reproduction. ...read more read less
