To establish a sustainable society, forest biomass or lignocellulosic biomass, which is the most abundantly accumulated biomass resource, plays an important role. Therefore it is critically important to establish systems for sustainable production of forest biomass, especially tropical forest resources. Forest tree biotechnology will play a very important role in such systems. Following the completion of whole genome sequence of <i>Populus</i>, tree bioscience and biotechnology have entered into "post-genomic era". However, although tropical <i>Acacia</i> is one of the most important tropical plantation tree in Indonesia and Malaysia, its biotechnology is still at a primitive stage. Because the <i>Acacia mangium</i> genome sequence data base is far beyond the ability of university laboratories, it is important to construct expressed-sequence tag (EST) data bases for <i>Acacia</i>. <i>A. mangium</i> EST data bases are quite useful for identifying genes that are possibly involved in the expression of a given trait, and can be exploited to detect <i>Acacia</i> genes which are orthologous to those of other model plants that are involved in secondary xylem formation. In addition, establishing efficient systems for <i>in vitro</i> regeneration of transformed <i>Acacia</i> and identification of genes and metabolites responsible for expression of commercially important traits are indispensable for genetic modification of the species. Importantly, these activities must be done to benefit global environment conservation and social welfare of local communities. In this review, the current status of <i>Acacia</i> biotechnology is outlined.
