摘要: 对傅氏凤尾蕨(Pteris fauriei)和狭眼凤尾蕨(Pteris biaurita)的叶绿体rps4-trnS区序列进行PCR扩增和序列分析, 再结合NCBI基因数据库中已发表的凤尾蕨科及其邻近类群的rps4-trnS区序列构建系统发育树来分析两者的亲缘关系。结果显示:傅氏凤尾蕨和狭眼凤尾蕨的rps4-trnS区序列未表现出明显差异。结合两者孢子体和配子体形态发育特征以及rps4-trnS区序列的证据,认为傅氏凤尾蕨和狭眼凤尾蕨为同种或为变种关系。

Abstract: This paper mainly discussed the phylogenetic relationship between Pteris fauriei and Pteris biaurita based on the combined rps4-trnS region sequences of Pteridaceae and the allied groups that have been published in GenBank. The result showed that: no significant difference between chloroplast rps4-trnS region sequences of P.fauriei and P.biaurita was detected. Therefore, P.fauriei and P.biaurita are most probably conspecific or variant relations based on our phylogenetic analysis combining the evidences of morphological characteristics of their sporophytes and gametophytes.

Key words: Pteris fauriei, Pteris biaurita, Pteridaceae, rps4-trnS region sequence
