Differentiation in DNA fingerprinting among species of the genusAcerL. in Campania (Italy)

Natural populations of species in the Acer genus occurring in Campania (southern Italy) were surveyed by screening seven microsatellite loci. Primer pairs for Acer pseudoplatanus L. microsatellite loci were analysed in six different species: Acer lobelii Ten., Acer campestre L., Acer pseudoplatanus L., Acer obtusatum W. et K., Acer neapolitanum Ten. and Acer monspessulanum L. The aim of the present study was to survey the genetic variability and genetic structure of natural populations of the Acer genus in Campania. The high degree of polymorphism observed in six different species of Acer makes these markers useful for investigating genetic variation at various spatial scales, and for the analysis of gene flow and of the mating system.
