Abstract:Araucaria angustifolia is a dioecious tree species that occurs in the southern part of Brazil. Because of the intense exploitation of the species due to its valuable wood, only 2% of the original population still remains. Twenty‐nine species‐specific and highly polymorphic microsatellite loci were developed from a genomic library enriched for AG/TC repeats. Levels of polymorphism were evaluated using a total of 16 adult trees from a natural population. An average of 8.1 alleles per locus was detected, and expected heterozygosity ranged from 0.63 to 0.72.
Keywords:Araucaria angustifolia  conservation  genetic diversity  microsatellite
