Acacia
Summary
The genus Acacia is composed of as many as 8000 species native to the tropics and subtropics. The commercially valuable species Acacia mangium is variously known as “Mangium”, “Black Wattle” and “Hickory Wattle”, and is traded as brown salwood. Its distribution covers the northern part of Queensland in Australia, Papua New Guinea and the Molucca Islands of Indonesia. Mangium is a fast-growing tree, relatively short-lived (30-50 years) and adapted to a wide range of acidic soils in most tropical lowlands. It is a pioneer species that colonize disturbed sites. Major plantations of A. mangium are grown in Southeast Asia for paper pulp. Wood from this species is used in furniture, handles of sporting goods, door frames and light construction. Plantations of A. mangium are also used for erosion control, shade and shelter. This species is playing an important role in efforts to sustain commercial supply of tree products while reducing pressure on natural forest ecosystems.
The Institute of Molecular Agrobiology, located at the National University of Singapore, has filed applications related to the genetic transformation of A. mangium with Agrobacteriumand to the regeneration of the species. The PCT applications disclose methods for transforming A. mangium with a gene of interest using A. tumefaciens. One of the recited methods uses stems as initial tissue to be transformed with the bacterium.
For patent documents in the United States, Australia and New Zealand, the ownership has changed to Temasek Life Sciences Laboratory Ltd.

WO 2001/53452 A2
|
Title – Regeneration and genetic transformation of acacia mangium
Methods for transforming explants of A. mangium with a gene of interest by co-cultivating A. tumefaciens having the gene of interest with pre-cultured explants of the tree species. In one of the methods the tissue selected for transformation is stems. Transgenic cells and plants of A. mangium are also part of the recited invention. Additional claims recite methods for the regeneration of non-transformed A. mangium from different tissues. |
