保护遗传学是运用遗传学的原理和研究手段,以生物多样性尤其是遗传多样性的研究和保护为核心的一门新兴学科。近几十年来,遗传学研究在生物多样性保护的理论和实践中发挥着越来越重要的作用。本文简要回顾了保护遗传学的发展历史、研究方向和涉及的概念,着重介绍了植物保护遗传学研究所取得的一些进展,包括植物系统发育重建和保护单元的确定、遗传多样性与物种和群体适应性之间的关系、群体遗传结构与保护策略的制定以及植物遗传资源的鉴定和利用等方面的内容,并强调保护遗传学研究是未来生物多样性和保护生物学研究中一个亟待加强的研究领域。

Conservation genetics is a new field of research focusing on the studies and practices of biodiversity conservation based on the principles and techniques of population genetics. During the past decades, genetic studies have made increasingly great contributions to biodiversity conservation in theory and practice. In this paper, we briefly introduce the concept and history of conservation genetics, and highlight progress in plant conservation genetics. Four major aspects of conservation genetics in plants are addressed, including plant phylogenetic reconstruction and identification of conservation units, the relationship between genetic diversity and species fitness, population genetic structure and conservation strategies, as well as the identification and utilization of plant genetic resources. In addition, the great importance of genetic studies in plant conservation is discussed.
