Genetic characterization of Portuguese allochthonous populations of Pinus nigra using ISSRs and SCoTs and extrapolation of their infraspecific taxonomy.

ABSTRACT: The Pinus nigra distribution in Portugal is restricted to six allochthonous populations with unknown origin and infraspecific taxonomy. This work intends to evaluate their genetic diversity, structure and relationships, and to infer about their infraspecific taxonomy by comparing molecular patterns produced by inter-simple sequence repeat and Start Codon Targeted markers among Portuguese and foreign samples with known taxonomy and provenance. 127 Portuguese P. nigra individuals were clustered per population. The genetic differentiation was higher within rather than among populations. The pooled molecular data indicated high genetic proximity among the Portuguese and foreign samples of subspecies laricio. However, the separate analysis per marker system demonstrated tha
