In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We
