摘要
利用AFLP分子标记技术,结合形态学特征观察和叶片纤维素等成分含量的测定,将来自4个省的9个不同居群的龙须草划分为4种生态型:窄叶类型(湖北)、浓绿叶类型(广西)、红秆类型(陕西)和宽叶类型(河南);来自同一地区的不同居群之间,遗传差异很小,聚为同一种生态型;同一居群内不同无融合生殖个体之间未检测到差异;分析了不同生态型之间的遗传差异和亲缘关系;讨论了AFLP技术在无融合生殖植物的分类和遗传学研究中的应用前景。
AFLP markers and morphological observation were used to identify the ecotypes of Eulaliopsis binata, which was reported as an apomictic species in Poaceae. The result showed that there is a large diversity among different ecotypes but a little within each population. By cluster analysis based on AFLP data, four ecotypes were identified as follows: slender-leaf ecotype (Hubei), deep-green-leaf ecotype(Guangxi), red-haulm ecotype (Shaanxi) and wide-leaf ecotype (Henan). The utilizations of AFLP markers in classification and further investigation of apomictic plants were discussed as well.
