Phylogenetic Relationships in the Genus <i>Spiraea</i> (Rosaceae) Inferred from the Chloroplast DNA Region, <i>trn</i>L-<i>trn</i>F

Abstract

The 26 taxa of genus <i>Spiraea</i> (Rosaceae) in 14 Korean taxa and four taxa of them doubled in the world itself were collected and investigated phylogenetic relationships within these taxa using the chloroplast <i>trn</i>L-<i>trn</i>F region. Sequence variation within the genus <i>Spiraea</i> was mostly due to insertion/deletion. Total alignment sequence of <i>trn</i>L-<i>trn</i>F region in genus <i>Spiraea</i> was 1004 positions, of which 126 were parsimony-informative, 149 variable, 23 singleton, and 847 constant characters. The base furtherance did not show a significant difference among total taxa. Although many taxa of genus <i>Spiraea</i> were well separated each other, many branches were not congruent with the taxon positions with botanical names. In addition, sequences of the chloroplast <i>trn</i>L-<i>trn</i>F region for same species are different from each other according to authors. The taxonomic identification of genus <i>Spiraea</i> are in need of revision

Plastid genome and its phylogenetic implications of Asiatic Spiraea (Rosaceae)

“…Spiraea , Calospira , Chamaedryon , and Glomerati ) and ten series within the genus have been widely accepted [ 4 ]. Previous phylogenetic analyses have revealed issues with traditional classifications based on inflorescence morphology, as the majority of sections are considered paraphyletic or polyphyletic [ 5 – 10 ]. However, most nodes in these phylogenetic trees could not receive strong support values based on limited molecular fragments, highlighting the need for the development of robust molecular markers within Spiraea .…”
