| Abstract: | Part of the large subunit of the ribulose-1,5-bisphosphate carboxylase gene (rbcL) was sequenced (1333 base pairs) from three species of gymnosperms:Ephedra sinica Gnetum parvifolium, Welwitschia mirabilis. Phylogenetic trees inferred from the neighbor joining, Wagner parsimony and maximum likelihood methods showed thatGnetum andWelwitschia were more closely related to each other than either is toEphedra within Gnetophyta, and the result supports previous cladistical analysis of morphological data. |
