Genetic comparison of newly discovered population of endangered Helianthus verticillatus (Asteraceae) found in Mississippi.

Determining the genetic structure of isolated or fragmented species is of critical importance when planning a suitable conservation strategy. Helianthus verticillatus (Asteraceae) is a sunflower species that is federally listed as an endangered species. The distribution of the species is only recorded to have five populations within three locations: Alabama, Tennessee, and Georgia. Recently, there was a new population discovered in Mississippi. In this study, the DNA of thirteen individuals within this recently discovered population were genotyped using nineteen nuclear SSRs originating from the cultivated sunflower (Helianthus annuus L.) expressed sequence tag (EST) database, which is known to be transferable to H. verticillatus and its putative parental taxa. The Mississippi population was then examined for genetic diversity to compare with the other five known populations. The results of this study shows a high percentage of molecular variance within and among populations at nuclear loci.
