Abstract

Nine (CT)n microsatellites were developed for tree of heaven, Ailanthus altissima, from invasive populations on the Mediterranean islands. These loci had seven to 12 alleles in 96 trees from five islands. Two loci had significant deficits of heterozygotes within islands while the other loci were in Hardy–Weinberg equilibrium, and four pairs of loci had significant linkage disequilibrium within a single island. These loci were also polymorphic in one to three individuals of the tree of heaven varieties, Ailanthus altissima erythrocarpa, Ailanthus altissima sutchuenensis and Ailanthus altissima tanakai, and the related species Ailanthus giraldii and Ailanthus vilmariniana.
