DNA barcoding is a revolutionary new technique for identifying species with unprecedented accuracy. Recently, it has been used to identify the genus Caragana, a large group of legumes native to Siberia and Mongolia. By sequencing the plant’s DNA, researchers were able to differentiate between closely related species and identify several that had not previously been known. This new information provides a better understanding of the evolution of the genus, and could help conservation efforts in the future.
