Structure of the large ribosomal subunit RNA of <i>Phytophthora megasperma</i>, and phylogeny of the oomycetes

The 5.8S and 28S rRNA sequences of the oomycete Phytophthora megasperma were determined in order to study the secondary structure of these molecules and to assess the phylogenetic position of the oomycetes among the eukaryotes. Preliminary results point to an affiliation between the oomycetes, dinoflagellates and ciliates, a cluster which seems related to the fungi. In the course of this work, we developed a set of primers which allow sequencing and PCR amplification of eukaryotic large ribosomal subunit RNA genes of a wide range of phylogenetically distant organisms.
