College. A comparison of native and cultivated Asclepias tuberosa
plants based on intersimple sequence repeat (ISSR)
Asclepias tuberosa, a.k.a. butterfly weed, is a member of the milkweed
family and is found throughout the majority of the contiguous United States. The plant has been traditionally valued for
its medicinal properties, and as its name suggests, its ability to attract
butterflies. With showy orange flowers,
butterfly weed is readily sold in garden centers and seed catalogs. However, native populations of the plant have
apparently been disappearing in the northeastern part of the United States, including New York State. For this project, we are determining whether
the cultivated plants purchased from various seed catalogs are genetically
distinct from native populations found in different areas of the United States including New
York, Oklahoma, Louisiana,
Iowa, and Tennessee.
We are comparing these plants by analyzing ISSR polymorphisms using a
PCR-based technique. Results will be
presented and discussed.
