The determination of nucleotide sequences in DNA, sequencing chloroplast genomes techniques, based on the use combinations a significant number genetic markers, as well nuclear genome are widely for inventory rare plant species, ecological monitoring and species diversity assessment. results our molecular analysis used to examine taxonomic identity phylogenetic relationship studied Iris collect...

To determine the evolutionary relationships among some members of geophytes collected from their natural habitat in Kulp-Diyarbakır we carried out molecular phylogenetic analysis one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and chloroplast (cpDNA) (intergenic spacer trnL-F). Despite using maximum likelihood done by two different source show differences it was identified tha...

Few studies have addressed the phylogeography of species of the Cerrado, the largest savanna biome of South America. Here we aimed to investigate the phylogeographical structure of Dalbergia miscolobium, a widespread tree from the Cerrado, and to verify its concordance with plant phylogeographical and biogeographical patterns so far described. A total of 287 individuals from 32 populations were...

The taxonomic and phylogenetic status of several taxa previously recognized as subspecies inAstragalus sect. Anthylloidei is re-assessed based on DNA sequences and morphologicalfeatures. We focused on Astragalus ebenoides (subsp. ebenoides and subsp. naghadehensis),Astragalus murinus (subsp. murins and subsp. bornmuelleri), Astragalus remotiflorus (subsp.remotiflorus and subsp. melanogramma), A...

Although polyploidy plays a fundamental role in plant evolution, the elucidation of polyploid origins is fraught with methodological challenges. For example, allopolyploid species may confound phylogenetic reconstruction because commonly used methods are designed to trace divergent, rather than reticulate patterns. Recently developed techniques of phylogenetic network estimation allow for a mor...

Species in the present study were compared based on their morphology, growth characteristics in culture, and DNA sequences of the nuclear ribosomal RNA gene operon (including ITS1, ITS2, 5.8S nrDNA and the first 900 bp of the 28S nrDNA) for all species and partial actin and translation elongation factor 1-alpha gene sequences for Cladosporium species. New species of Mycosphaerella (Mycosphaerel...
