| Research Abstract |
The purpose of this project was to create an internet-based public database of DNA samples from natural populations of ecologically and economically important forest tree species from Asia. The constructed database contains all information pertinent to taxonomy, geographic origin and type of material etc. It features search and order engine similar to that used by e-commerce companies. The DNA samples stored in the database are distributed at no cost to any non-profit scientist with established credentials willing to pay postage delivery fee. The database is stored on the website maintained by our laboratory : http://genetics.biology.kyushu-u.ac.ip.
The number of extant tree species in Asia is vast. Thus, studies of all tree components are neither possible nor they are necessary. We therefore focused on species with greatest ecological and economical significance, which serve as a source of timber, fuel wood, cane or fruit. By now, species fulfilling this condition have been identified in individual countries in Asia. In particular, our effort was focused on the following genera : Bambusa, Calamus, Rhizophora, Dipterocarpus, Shores, and Tectona. Samples were collected in the following countries : Japan, Malaysia, Thailand, China, India, Sri Lanka, Vietnam, Seychelles and Madagascar. For the time being, the constructed database contains more than 2000 samples from more than 200 species of tropical trees from Asia and Madagascar. Recently, through collaboration with Swedish and Russian scientists we obtained a unique collection of samples representing all species of the genus Larix occurring in Asia. The samples are now being entered into our database and will be made available for public access later this year.
In the course of the project, three MSc and two BSc programs were completed.
