Phylogenetic implications of nuclear rRNA IGS variation in Stipa L. (Poaceae).

ABSTRACT: The article takes up the problem of deficiency of molecular marker, which could illustrate molecular variability as well as phylogenetic relation within the genus of Stipa L. (Poaceae). Researches made so far hadn't delivered sufficient information about relationships between particular taxa from the genus of Stipa. In the present study, we analyzed variability and phylogenetic informativeness of nuclear ribosomal DNA in six species from the genus against five other species from Poaceae including a division of this region into functional elements and domains. Our results showed that the intergenic spacer region, and especially its part adjacent to 26 S nrDNA, is a molecular marker giving a real chance for a phylogeny reconstruction of Stipa. The region seems to be the most phylogenetically
