摘要
组织内含天然橡胶的植物统称为产胶植物.产胶植物的乳管是合成和贮存天然橡胶的特化细胞,乳管细胞及其内部橡胶粒子的发生、发育与植物的产胶能力密切相关.因此,研究产胶植物的乳管结构及其分化发育对天然橡胶产业的发展具有重要的意义.橡胶粒子、黄色体和F-W复合体(Frey-Wyssling complex)是橡胶树乳管的特化细胞器,机械伤害促进乳管的分化,茉莉酸是调节次生乳管分化的关键信号分子,但橡胶树乳管分化发育的分子机制仍未完全解析.本文综述了当前主要产胶植物乳管结构和分化发育方面的研究进展,并阐述了杜仲、橡胶草、银胶菊与橡胶树的乳管在分布、形态结构上的区别.本文将为深入研究产胶植物的乳管生物学奠定理论基础.
The plants that contain natural rubber are called rubber-producing plants, in which the laticifer is a special cell to synthesize and storenatural rubber. The differentiation and development of laticifers and rubber particles inside are closely related to the rubber yield.Therefore, it is important to understand the structure and development of laticifer in rubber-producing plants. Rubber particle, lutoid,and F-W complex are the special ultrastructures of laticifer in rubber trees. Secondary laticifer can be significantly induced bymechanical wounding including tapping, and jasmonic acid (JA) is a key signal to regulate the differentiation of secondary laticifer.However, the molecular mechanism of laticifer differentiation is still not fully clear. In this article, the research progress on thestructure and differentiation of laticifer in the major typical rubber-producing plants is reviewed, and the distribution andmorphological structure of laticifer in Eucommia ulmoides, Taraxacum kok-saghyz, and Parthenium argentatum are different fromthose of rubber tree. This paper will lay a theoretical foundation for futher studies on the laticifer biology of rubber-producing plants.
