Genetic variation of Shorea (Dipterocarpaceae) in Indonesia

The dipterocarps are the most important tree family in tropical Southeast-Asia both from an ecological and an economic perspective. Indonesia, in particular Sumatra and Kalimantan, is the region of the highest species diversity of the dipterocarps. Information on the phylogeny of Indonesian dipterocarps is scarce, and intraspecific genetic variation has been rarely investigated. We plan to observe patterns of variation within and among species of the species-rich genus Shorea at uniparentally inherited DNA of chloroplasts and by means of the anonymous AFLP technique. Results will be used to set up a molecular phylogeny of the genus. The analysis of intraspecific genetic variation of selected taxa will give the opportunity to infer the role of drift, isolation, hybridization and other factors in the evolution of dipterocarps. We want to test if the spatial distribution of genetic variation at particular marker loci allows to develop unambiguous tools for the identification of the origin of plant material (including wood). Such methods may gain importance for the control of the origin of wood from certified forest enterprises.
