Sumario:Tung tree (Vernicia fordii) is an industrially important oil-bearing woody plant of the Euphorbiaceae family. Functional studies of tung tree at the molecular level are limited by the lack of an efficient transgenic system. The Agrobacterium rhizogenes-mediated hairy root generation system is an alternative to typical plant transformation systems. However, its application in many plants has been blocked due to the inability of existing methods to induce hairy roots. Thus, it is critical to build a method suitable for the hairy induction of the specific plant of interest. In this study, a modified method for tung tree was developed, and it is the first report that hairy roots could be effectively induced in the stem of tung tree. With the method, an average of 10.7 hairy roots per seedling were generated in tung tree, approximately 67% of seedlings produced transgenic hairy roots and approximately 13.96% of the hairy roots of these seedlings were transgenic. This modified method is also suitable for the hairy root induction of two other oil-bearing plants of the Euphorbiaceae family, Ricinus communis and Vernicia montana. This modified method will accelerate functional studies of tung tree at the molecular level and also shed light on plants lacking a transgenic system.
