Abstract:

The sequence of Ls-rRNA 5‘ terminal 347 nucleotides of Rohdea japonica (Thunb.)

Roth has been precisely determined. A phylogenetic tree constructed based on the rRNA

nucleotide sequences of this and five other angiosperm species and an algal species (Porphyri-

dium purpureum) is in accordance with the taxonomical system generally accepted. The result

indicates that this method is of a high resolution for revealing differences and relationships am-

ong families and genera. It is also shown by our result that the difference between Rohdea and

the Poaceae is greater than that between the Solanaceae and the Brassicaceae. Therefore, it may

be considered that the divergence between these two groups took place at early stage of evolu-

tion of monocotyledons.
