Brazilian sedge reproduces sexually but without DNA reshuffling, producing genetic clones
Sexual reproduction usually reshuffles genetic information, creating offspring that differ from their parents. But one small plant takes an unexpected route.
AI Summary
A study in *Nature* reports that the Brazilian beak‑sedge *Rhynchospora tenuis* reproduces sexually, producing pollen, fertilizing egg cells, and setting seeds. However, the plant lacks the usual DNA reshuffling that occurs between parental chromosomes during meiosis. As a result, the offspring inherit an identical genetic makeup to their mothers, effectively reproducing as clones. The research was led by André Marques at the Max Planck Institute for Plant Breeding Research in Cologne.
