木质素是一种植物体内重要的大分子有机物质,其含量仅次于纤维素。在增强植物体机械强度、抵御外界不良环境侵袭以及疏导组织水分运输等方面起着重要作用。木质素的含量及组成对果实品质及抗逆性等有重要的影响,如核桃内果皮中木质素的含量及组成对于核桃的果实品质、内果皮发育、果皮的完整性(露仁)等有直接影响。因此,本文重点对植物木质素生物合成及其关键酶基因的研究进展进行综述,为从木质素合成领域着手改良果实品质奠定理论基础。
Abstract：Lignin is one of important macromolecular organic materials,which content is lower than that of in botanic field. It plays an important role in enhancing plant mechanical strength to resist the undesirable descent from the outside environment and transporting the conducting tissue water. Lignin contents and composition have important effect on fruit quality and stress resistance,for example,the lignin contents and composition of walnut endocarp has direct influence,such as walnut fruit quality,endocarp development,the integrity of the endocarp( bared nut) and so on. Therefore,this paper focuses on plant lignin biosynthesis and summarizes the research progress of key enzyme genes in order to set a theoretical basis for the fruit quality improvement in the lignin synthesis field.
