摘要:
从形态特征和地理分布特征比较分析云南真藓和细叶真藓的区别,通过对核糖体DNA的内转录间隔区序列分析研究,对二者进行分子水平鉴定。对包括真藓属及相关属的6种植物的ITS序列进行扩增和测序,使用DNAMAN和MEGA3.0软件对获得的ITS序列数据进行分析。结果表明,云南真藓和细叶真藓的ITS-1和ITS-2区在序列长度,G+C含量上均存在差异。UPGMA法聚类分析表明,这种差异发生在种级水平。研究结果表明,云南真藓和细叶真藓应视为独立的两个种。
Abstract:
Morphological characteristics and ecological distributions of Bryum yuennanense and B.capillare were analyzed in this study. Molecular identifications were done by the analysis of Bryum yuennanense and B.capillare ITS region of the six species in the related genus were amplified and sequenced. The sequences data were analyzed by DNAMAN and MEGA3.0. The results showed that the length of sequences and content of G+C of ITS1 and ITS2 were different between B.yuennanense and B.capillare. Phylogenetic tree based on ITS sequences data was conducted by UPGMA method,which showed some variations at the level of species. B.yuennanense and B.capillare should be assigned as two different taxa.
