ABSTRACT: Random amplified polymorphic DNA was used in analysing the relationship among twenty-six speices of Amanita from Mangshan, Hunan. Of 40 primers, 6 ones generated reproducible RAPD profiles, and each one produced 1-10 bands. Two primers (OPG15 and OPH04) could differentiate 26 species of Amanita by its RAPD profiles. The similarity coefficients obtained from profiles generated by six primers among Amanita were about 20-60%. A dendrogram was constructed using average linkage clustering for clustering analysis. It indicated that there were two groups in 26 species and some species with ring and membranous volva clustered a group which coincided with morphological classification.

本文对采自湖南莽山的26种鹅膏菌属真菌进行了随机扩增多态性DNA分析，40个随机引物中筛选出扩增效果较好的6个引物，每个引物能产生1～10条DNA条带，获得的RAPD谱带清晰并呈现多态性OPG15、OPH04两个引物扩增的RAPD谱带能将26种鹅膏菌完全区分开来，通过6个引物的RAPD分析获得的平均相似性系数表明种与种之间的相关系数在20―60%之间，平均链锁聚类分析可将26种鹅膏菌分为二大类，且一些具菌环和苞状菌托的种类聚在一起，与形态分类基本相吻合。

Five pairs of 45S rDNA loci and two pairs of 5S rDNA signals were detected on chromosomes of Cucurbita moschata Duch. Luffa cylindrical Roem. contained five pairs of 45S rDNA loci and one pair of 5S rDNA loci. In Benincasa hispida Cogn., two pairs of 45S rDNA sites and one pair of 5S rDNA site were detected. In this species, 5S rDNA and one pair of the 45S loci were collocated closely in chromosome 7S. 45S rDNA chromosomal distribution patterns were highly conserved among the three species, althoufh their number varied markedly. The 5S rDNA sites on chromosomes among the three species were highly polymorphic.

南瓜有5对45S rDNA位点， 2对5S rDNA位点；丝瓜具有5对45S rDNA位点， 1对5S rDNA位点；冬瓜具有2对45S rDNA位点， 1对5S rDNA位点， 5S rDNA位点与其中一对45S rDNA位点都位于7号染色体短臂上，并在物理位置上紧密相邻。45S rDNA在这3种作物染色体上数目变化较大，但在染色体上都倾向分布在短臂末端，其分布模式较为一致。5S rDNA在这3种作物染色体上数目相对保守，但在染色体上分布的位置变化较大。
