A MOLECULAR REEXAMINATION OF INTROGRESSION BETWEEN HELIANTHUS ANNUUS AND H. BOLANDERI (COMPOSITAE)

A MOLECULAR REEXAMINATION OF INTROGRESSION BETWEEN HELIANTHUS ANNUUS AND H. BOLANDERI (COMPOSITAE) Heiser (1949) hypothesized that a weedy race of Helianthus bolanderi had originated by the introgression of genes from H. annum into a serpentine race of H. bolanderi. Although Heiser's investigation of these species is frequently cited as one of the best examples of introgression in plants, definitive evidence of gene exchange is lacking (Heiser, 1973). To determine whether the weedy race of H. bolanderi actually originated via introgression, we analyzed allozyme, chloroplast‐DNA (cpDNA), and nuclear‐ribosomal‐DNA (rDNA) variation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Evolution Oxford University Press

Abstract

Heiser (1949) hypothesized that a weedy race of Helianthus bolanderi had originated by the introgression of genes from H. annum into a serpentine race of H. bolanderi. Although Heiser's investigation of these species is frequently cited as one of the best examples of introgression in plants, definitive evidence of gene exchange is lacking (Heiser, 1973). To determine whether the weedy race of H. bolanderi actually originated via introgression, we analyzed allozyme, chloroplast‐DNA (cpDNA), and nuclear‐ribosomal‐DNA (rDNA) variation.
