متن کاملAn ITS phylogeny of Balsamorhiza and Wyethia (Asteraceae: Heliantheae).
The relationships among the species of Balsamorhiza and Wyethia (Asteraceae: Heliantheae) were examined using data from the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA. The ITS sequences were obtained from nine species of Balsamorhiza and 14 species of Wyethia as well as seven outgroup genera. Five of the outgroup genera were members of the subtribe Engelmanniinae of t...
