Phylogenetic relatedness of several agarwood-producing taxa (Thymelaeaceae) from Indonesia

Indonesia is home to several tree taxa that are harvested for agarwood. This highly valuable oleoresin ironically was the cause for some species to become vulnerable due to gluttonous human activity. However, information on the genetic diversity of these endangered trees is limited. In this study, 2...

This highly valuable oleoresin ironically was the cause for some species to become vulnerable due to gluttonous human activity.
