Extending Specimens to Save Plant DNA: Structuring Department DNA Collections in Times of Biodiversity Loss.
González-Toral C, Cires E
Biodiversity Conservation
PubMedPlants going extinct today — including wild relatives of foods you eat and flowers in your local park — are taking their unique genetic blueprints with them forever, and preserved DNA could one day help restore or study them.
When a plant species disappears, we lose not just the plant but all the unique genetic information locked inside it. Scientists are proposing that museums and universities use their collections of dried, pressed plants — some centuries old — to extract and bank DNA before it degrades. Having organized, well-structured DNA libraries gives future researchers a fighting chance to understand, conserve, and potentially revive plants we're losing right now.
Key Findings
Plant biodiversity DNA banks are currently scarce relative to the scale and pace of ongoing plant species loss globally.
Existing herbarium specimens (dried plant collections in museums and universities) represent an underutilized source for extracting and preserving plant DNA.
Structuring departmental DNA collections with clear protocols could significantly extend the value of physical specimen archives for conservation and research.

Scientists are calling for better-organized plant DNA banks to preserve genetic material from species at risk of extinction. By leveraging existing dried herbarium specimens, institutions can build structured DNA collections before irreplaceable plant diversity disappears.
