| Abstract: | Transgenic trees with low lignin content,high cellulose content,high conversion efficiency of sugar,and excellent wood properties were achieved by genetic engineering,which have important research value for the directional application in pulping and paper making,biomass energy refining and wood building and decorative materials.In this paper,the effects of lignin and cellulose gene regulation on growth phenotype,cell wall chemical component and distribution,tissue cells morphology and ultrastructure of cell wall in transgenic trees were reviewed in detail.And the prospects for future research and development direction of transgenic forest are put forward.The purpose of this article is to provide theoretical guidance for the directional cultivation of high quality and fast growing plantations in China. |
