Dataset Information

A new species of Ranunculus (Ranunculaceae) from Western Pamir-Alay, Uzbekistan.

ABSTRACT: New data on the phylogeny of four rare and endemic species of RanunculusL.sect.Ranunculastrum DC. of western Pamir-Alai, one of which is new to science, have been obtained. Ranunculustojibaevii sp. nov., from the Baysuntau Mountains, Western Hissar Range of Uzbekistan, is described. The new species is closely related to R.botschantzevii Ovcz., R.convexiusculus Kovalevsk. and R.alpigenus Kom., but differs in the blade of the radical leaves, which is rounded-reniform, segments 3-5-dissected, each 2-5-partite with elongated, rounded apical lobes. A phylogenetic analysis, using both the nuclear ribosomal internal transcribed spacer (ITS) and cpDNA (matK, rbcL, trnL-trnF), was informative in placing R.tojibaevii in context with its most closely-related species. Discussion on the geographic distribution, updated identification key, a detailed description, insights about its habitat and illustrations are provided.

Project description:Worldwide, the genus Ranunculus includes approximately 600 species and is highly genetically diverse. Recent taxonomic reports suggest that the genus has a monophyletic origin, divided into two subgenera, and consists of 17 sections. The Central Asian country of Kazakhstan has 62 species of the genus that have primarily been collected in the central part of the country. The latest collection trips in southern parts of the country have led to the description of a wider distribution area for Ranunculus and the identification of a new species Ranunculus talassicus Schegol. et A.L. Ebel from Western Tien Shan. Therefore, in this study, attempts were made to assess the molecular taxonomic positions of R. talassicus and two other species endemic to the Central Asian region R. karkaralensis Schegol. and R. pskemensis V.N. Pavlov in relation to other species of the genus, using internal transcribed spacer (ITS) molecular genetic markers. The ITS-aligned sequences of 22 local Central Asian accessions and 43 accession sequences available in the National Center for Biotechnology Information (NCBI) database allowed the construction of a maximum parsimony phylogenetic tree and a Neighbor-Net network. The results indicated that R. talassicus and R. pskemensis could be assigned to section Ranunculastrum. Additionally, an assessment of the network suggested that R. pskemensis was the rooting taxon for the group of species containing R. talassicus, and that R. illyricus L. and R. pedatus Waldst. & Kit. were founders of a prime rooting node for the Ranunculastrum section of the genus. The ITS-aligned sequences showed that R. karkaralensis was indifferent with respect to three other species in the Ranunculus section of the genus, i.e., R. acris L., R. grandifolius C.A. Mey., and R. subborealis Tzvelev. The study indicated that the assessments of ITS-based phylogenetic tree and Neighbor-Net network provided new insights into the taxonomic positions of three endemic species from Central Asia.
