Abstract:

Poplar (Populus spp.) is one of the most important tree species used for land greening and industrial timber production in China, and efficiently and precisely breeding new cultivars with rapid growth, high quality and strong stress tolerance will be an important direction for the future theoretical and technological development in poplar breeding. The Agrobacterium-mediated genetic transformation system has been the critical technology for shortening breeding cycle and increasing breeding efficiency. A large number of researches have been conducted on developing the Agrobacterium-mediated genetic stable transformation system for poplar since it was proved to be a native host of Agrobacterium in 1980s. We performed a comprehensive analysis of existing literatures, reviewed the historical process of constructing Agrobacterium-mediated genetic transformation system in different poplar species, summarized the main factors affecting transformation efficiency, and also discussed some future perspectives in this area. This review will provide useful information for further improving the poplar transformation efficiency and present reference protocols for establishing transformation systems in recalcitrant plant species and elite cultivars widely applied in production.

Key words: Populus, genetic transformation, Agrobacterium tumefaciens, A. rhizogenes, tissue culture regeneration
