To evaluate the contribution of historical contact vs. long‐distance gene flow in the formation of a broad hybrid zone in central and northern Georgia that involvesAesculus pavia,A. sylvatica, andA. flava, three cpDNA regions (matK,trnD‐trnT, andtrnH‐trnK) were analyzed. The maternal inheritance of cpDNA inAesculuswas confirmed via sequencing ofmatKfrom progeny of controlled crosses. Restriction site analyses identified 21 unique haplotypes among 248 individuals representing 29 populations from parental species and hybrids. Haplotypes were sequenced for all cpDNA regions. Restriction site and sequence data were subjected to phylogeographic and population genetic analyses. Considerable cpDNA variation was detected in the hybrid zone, as well as ancestral cpDNA polymorphism; furthermore, the distribution of haplotypes indicates limited interpopulation gene flow via seeds. The genealogy and structure of genetic variation further support the historical presence ofA. paviain the Piedmont, although they are at present locally extinct. In conjunction with previous allozyme studies, the cpDNA data suggest that the hybrid zone originated through historical local gene flow, yet is maintained by periodic long‐distance pollen dispersal.}, number={3}, journal={AMERICAN JOURNAL OF BOTANY}, author={Modliszewski, JL and Thomas, DT and Fan, CZ and Crawford, DJ and DePamphilis, CW and Xiang, QY}, year={2006}, month={Mar}, pages={377–388} }
