Research Methods and Influencing Factors of Genetic Diversity of Rare and Endangered Plants

遗传多样性是生物多样性的基础。深入了解珍稀濒危植物遗传多样性水平及其影响因素,对其保护及可持续利用具有十分重要的意义。近年来,随着标记技术的快速发展,珍稀濒危植物遗传多样性研究的发展得到极大的推进。概述了研究珍稀濒危植物的常用标记方法,包含形态标记、染色体标记、生化标记及DNA分子标记。同时,归纳了影响珍稀濒危植物遗传多样性的影响因素。

Since genetic diversity is the foundation of biological diversity,an in-depth understanding of the genetic diversity of rare and endangered plants and their influencing factors is of great significance to carry out the protection and sustainable utilization.In recent years,with the rapid development of marker technology,researches about the genetic diversity of rare and endangered plants have been greatly promoted.This paper provided an overview of methods of markers commonly used,including morphological marker,chromosomal marker,biochemical marker and DNA molecular marker.In addition,it summarized the impact of factors influencing the genetic diversity of rare and endangered plants.
