Abstract	The genetic variation within and between 13 populations (385 individuals) of Pinus uncinata was analyzed with ten chloroplast microsatellite markers. Both the infinite allele mutation and stepwise mutation model (SMM) have been applied to the analysis of the genetic structure and the geographical distribution of haplotypic variation. High level of genetic diversity and low but significant differentiation among compared population were found. Three marginal populations, Sierra de Cebollera, Margaride Mountains and Sierra de Gúdar are strongly differentiated from the rest. Mutations following SMM-like process contributed significantly to the regional differentiation. The pattern of genetic structure observed in mountain pine is common in conifers with a wide distribution range. Lack of significant genetic structuring may be a result of a recent fragmentation of a historically larger population and/or interspecific hybridization and introgression. The southernmost populations from the Sierra Cebollera and the Sierra de Gúdar are the most genetically distinct. This suggests a long period of spatial isolation and/or origin from different ancestral populations.
