Genetics Section Kuenzi, Ashley [1], Culley, Theresa M. [2], Wallace, Lisa Ellen [3], Nepokroeff, Molly [4]. Interspecific hybridization and gene flow among established populations of Schiedea salicaria and S. menziesii. Gene flow in a hybrid zone between adjacent parental populations has implications for allelic variation between hybrids and their parents, which could affect the evolution of breeding systems in plants. In the case of interspecific hybridization between two species of woody shrubs expressing different breeding systems in the mountains of Maui, Schiedea salicaria and S. menziesii, the genetic relationship between putative hybrids and the parental populations is largely unknown. Chloroplast microsatellite markers were developed at five loci to gain a genetic characterization of each parent and the putative hybrid population in order to detect discernable maternal gene flow. Variation was observed in the five loci, resulting in thirteen different haplotypes. Interestingly, each observed haplotype is unique amongst the three populations, suggesting no maternal gene flow and strong population structure. Broader Impacts:
