Exploring Echinacea's enigmatic origins
Date:3/5/2010

This release is available in Spanish.

An Agricultural Research Service (ARS) scientist is helping to sort through the jumbled genetics of Echinacea, the coneflower known for its blossoms--and its potential for treating infections, inflammation, and other human ailments.

Only a few Echinacea species are currently cultivated as botanical remedies, and plant breeders would like to know whether other types also possess commercially useful traits. ARS horticulturist Mark Widrlechner, who works at the ARS North Central Regional Plant Introduction Station (NCRPIS) in Ames, Iowa, is partnering in research to find out how many distinct Echinacea species exist. Previous studies have put the number between four and nine species, depending on classification criteria.

Working with Iowa State University scientists, Widrlechner selected 40 diverse Echinacea populations for DNA analysis from the many populations conserved at the NCRPIS. Most of these Echinacea populations were found to have a remarkable range of genetic diversity.

DNA analysis suggested that when much of North America was covered with glaciers, Echinacea found southern refuges on both sides of the Mississippi River. But when the glaciers receded after thousands of years, the groups came together as they moved northward and began to hybridize, which might have blurred previous genetic distinctions.

The research team also analyzed the same populations for chemical differences in root metabolites. These metabolites, which are often essential for survival and propagation, can vary widely among species and may have benefits for human-health.

Using this approach, researchers were able to identify clear distinctions among all 40 populations. These distinctions were organized into three composite profiles that accounted for a
