The genus Ranunculus L., with a worldwide distribution, is the largest member of the Ranunculaceae. Here, nuclear ribosomal internal transcribed spacer (ITS) sequence data and chloroplast trnLF sequence data were used to analyze phylogenetic relationships among members of the annual and perennial (Group Praemorsa, Group Rhizomatosa, Group Grumosa and Group non-Grumosa) species of Ranunculus...

In order to compare the efficiency of morphological traits and molecular markers in distinguishing the Consolida species, molecular analysis using nrDNA ITS and cpDNA trnL-trnF with maximum parsimony and Bayesian methods were done in a total of 34 species and forma representing 28 species of Consolida, 6 species of Aconitella, plus two species of Delphinium and two species of Aconitum as out gr...

We developed 22 SSRs by using 3 approaches, RAHM (random amplified hybridization microsatellites), 5’ anchored PCR methods and an enriched genomic library. Seventy of 22 SSRs could be successfully amplified for Pyrus spp., which showed highly polymorphic. Sixty Asian pear accessions from 6 Pyrus species were genetically identified by 9 SSR markers with a total of 133 putative alleles. The SSR m...

BACKGROUND AND AIMS Nothoscordum gracile is an apomitic tetraploid widely distributed throughout the Americas and naturalized in many temperate regions of other continents. It has been suggested to form a species complex with sexual and apomictic N. nudicaule and N. macrostemon. Tetraploids of these species also share a structurally heterozygous chromosome complement 2n = 19 (13M + 6A). In this...

Phylogenetic relationships among 122 species of Lauraceae representing 44 of the 55 currently recognized genera are inferred from sequence variation in the chloroplast and nuclear genomes. The trnL-trnF, trnT-trnL, psbA-trnH, and rpll6 regions of cpDNA, and the 5' end of 26S rDNA resolved major lineages, while the ITS/5.8S region of rDNA resolved a large terminal lade. The phylogenetic estimate...

Seventy-eight polymorphic cpDNA (chloroplast DNA) characters were found in 13 closely related taxa from Eucalyptus series Amygdalinae (subgenus Monocalyptus) and seven potential outgroup taxa. The strict consensus of six cladograms generated from cpDNA data confirmed monophyly of Monocalyptus. However, cpDNA phylogeny within Monocalyptus was incongruent with taxonomic classification, being more...

Cladistic analyses of DNA sequences from the nuclear rDNA internal transcribed spacer region and cpDNA rps16 intron and, for a subset of taxa, the cpDNA trnF-trnL-trnT locus were carried out to evaluate the monophyly of Cymopterus and to ascertain its phylogenetic placement among the other perennial genera of Apiaceae (Umbelliferae) subfamily Apioideae endemic to western North America. To eluci...
