Power and limitations of the chloroplast trnL (UAA) intron for plant DNA barcoding
DNA barcoding should provide rapid, accurate and automatable species identifications by using a standardized DNA region as a tag. Based on sequences available in GenBank and sequences produced for this study, we evaluated the resolution power of the whole chloroplast trn L (UAA) intron (254-767 bp) and of a shorter fragment of this intron (the P6 loop, 10-143 bp) amplified with highly conserved...
متن کاملThe Phylogeny of Calligonum and Pteropyrum (Polygonaceae) Based on Nuclear Ribosomal DNA ITS and Chloroplast trnL-F Sequences
This study represents phylogenetic analyses of two woody polygonaceous genera Calligonum and Pteropyrum using both chloroplast fragment (trnL-F) and the nuclear ribosomal internal transcribed spacer (nrDNA ITS) sequence data. All inferred phylogenies using parsimony and Bayesian methods showed that Calligonum and Pteropyrum are both monophyletic and closely related taxa. They have no affinity w...
متن کاملThe use of chloroplast DNA to resolve plant phylogenies: noncoding versus rbcL sequences.
Direct sequencing of polymerase chain reaction products is now an expanding area of plant systematics and evolution. Within angiosperms the rbcL gene has been widely sequenced and used for inferring plant phylogenies at higher taxonomic levels. Unfortunately rbcL does not usually contain enough information to resolve relationships between closely related genera, such as Hordeum, Triticum, and A...
متن کاملPhylogeny of Malpighiaceae: evidence from chloroplast ndhF and trnl-F nucleotide sequences.
The Malpighiaceae are a family of ∼1250 species of predominantly New World tropical flowering plants. Infrafamilial classification has long been based on fruit characters. Phylogenetic analyses of chloroplast DNA nucleotide sequences were analyzed to help resolve the phylogeny of Malpighiaceae. A total of 79 species, representing 58 of the 65 currently recognized genera, were studied. The 3' re...
متن کاملGenetic diversity of Arum L. based on plastid marker
TrnL-F region including intron trnL (UAA) and trnL (UAA) - trn (GAA) spacer in the large single-copy region of the chloroplast genome is widely used to infer phylogenetic relationships in plants. In this study, we obtained the trnL-F sequences from 8 samples of Arum L. in Iran. Phylogenetic analyses were conducted by the Bayesian inference, maximum parsimony, and maximum likelihood methods. The...
