摘要
茶树[Camellia sinensis(L.)O.Kuntze]起源于中国的西南地区,在由起源地向中国其他地区和世界其他地区传播的过程中,发生了从形态学水平到细胞水平再到分子水平的一系列演化。对茶树遗传演化的研究,是茶树基础生物学的一个基本问题,也是茶树种质资源研究的重要方面。近年来,各种新技术、新方法被广泛应用于研究茶树遗传演化关系,取得了一定的进展。从形态学、细胞学、生物化学、分子生物学方面对茶树遗传演化研究取得的进展进行了综述,分析了SSR(Simple Sequence Repeat)标记在植物遗传演化中的应用,探讨了SSR标记在茶树遗传演化研究中的应用前景,旨为进一步深入研究中国茶树遗传多样性、亲缘关系及演化路径分析提供参考。
Tea plant [Camellia sinensis （L.） O. Kuntze], which originated in the southwest of China, took place a series of evolution from the level of morphology to the cytology level and to molecular level as it spread from the original center to other parts of China and elsewhere in the world. The research on the tea genetic evolution is not only a fundamental issue of tea biology but also an important aspect of the study of tea genetic resources. In the recent years, new technologies and methods have been widely applied in the study of the genetic evolution of tea plant. Some significant progress had been made so far. In this paper, we summarized the studies on the tea genetic evolution in the aspects of morphology, cytology, biochemistry and molecular biology of tea plant. The applications of SSR markers in genetic evolution of plants and its prospects in tea plant were discussed. The purpose is to provide some references for further study of the genetic diversity of tea in China and related analysis of the evolution.
