植物染色体图象分析数据库在芸苔族分类研究中的应用

APPLICATION OF THE DATABASE OF CHROMOSOME IMAGE ANALYSIS IN TAXONOMICAL STUDIES OF BRASSICEAE

本文首次用电脑图象分析手段对芸苔族5属13种植物进行了核型分析。其中蓝花子Raphanussativus var.raphanistroides、白芥Sinapis alba等植物的核型分析结果,都是国内外首次报道的。笔者建立了十字花科芸苔族植物的染色体数据库,这是国内外第一个专科性的植物染色体图象分析数据库,并且首次将染色体图象分析数据库应用于分类学研究。例如,比较分析芸苔族植物种间的亲缘关系和分类地位,以及探索物种之间的演化关系,得到了若干新的核型论据。笔者认为,植物染色体图象分析数据库在植物分类学研究中具有应用前景。

Recently the authors applied the chromosome image analysis in the study of Bras-siceae and obtained the following results. 1. The authors apllied the image analysis for the first time in the study of the karyotype of 13 species of Brassiceae. The karyotype data, karyograms, idiograms and karyotype formulae of Raphanus sativus var. raphanistroides and Sinapis alba are reported in this paper. 2. The authors have established the database of chromosome image analysis of Cruciferae, including five genera and 13 species. This is the first database of chromosome image analysis of Cruciferae in China and abroad. 3. The authors applied the database of chromosome image analysis for the first time in the taxonomical studies of Brassiceae, for example, to study the relationship and evolution of some species of Brassica. As a result they got some karyotype data which might be useful to plant tax-onomists. It is suggested that the database of chromosome image analysis be very useful to the plant taxonomical studies.
