Phylogenetic relationships in Helianthus (Asteraceae) based on nuclear ribosomal DNA internal transcribed spacer region sequence data
Author(s): E. E. Schilling, C. R. Linder, R. D. Noyes and L. H. Rieseberg
Journal: Systematic Botany
Article Topic(s): Genetics,Systematics
Research Setting(s): Laboratory
Species Referenced: Helianthus carnosus (Lakeside sunflower), Helianthus debilis (Cucumberleaf sunflower), Helianthus strumosus (Paleleaf woodland sunflower),
AbstractExamines the phylogenetic relationships among 46 species of Helianthus and two species of Phoebanthus using internal transcribed spacer regions of the nuclear ribosomal DNA. Based on patterns of genetic and geographic distribution, the ancestor to this genus may have been confined to the extreme southeastern US.
