TrnL–trnF Intergenic Spacer and trnL Intron Define Major Clades Within Luzula and Juncus (Juncaceae): Importance of Structural Mutations

Journal of Molecular Evolution, 2004
Seven hundred fifty-two to one thousand ninety-seven base pairs of the trnL intron and trnL- trnF intergenic spacer of the chloroplast DNA of 55 Juncaceae taxa (Juncus, Luzula, Rostkovia, and Oxychloë) was sequenced. Seventeen structural mutations (13 indels marked A to M, 3 parts of the trnF pseudogene, and insertion "o" within a pseudogene) within ...

Phylogenetic relationships of Carpha and its relatives (Schoeneae, Cyperaceae) inferred from chloroplast trnL intron and trnL–trnF intergenic spacer sequences

Molecular Phylogenetics and Evolution, 2004
Within the tribe Schoeneae (Cyperaceae), the relationships between Carpha and its relatives have not been certain, and the limits and definition of Carpha have been controversial. Further, the relationships of species within Carpha have been unclear.

Molecular evolution of the trnLUAA intron in bryophytes

Molecular Phylogenetics and Evolution, 2005
Structure, variability, and molecular evolution of the trnL(UAA) intron in bryophytes (mosses and liverworts) is analyzed based on more than 1000 sequences representing all classes, including comparisons of lengths and GC-contents, sequence similarities, evolutionary rates and ti/tv ratios of the major lineages and selected genera.

Species identification using sequences of the trnL intron and the trnL-trnF IGS of chloroplast genome among popular plants in Taiwan

Forensic Science International, 2006
Forensic botanical comparison can be hampered by the lack of appropriate DNA databases. While DNA sequence databases for many mitochondrial loci have been established for the identification of animal species, less is known regarding the genomes of plants.

Variability of the trnL plastid gene’s intron in the Faboideae species (Fabaceae)

Russian Journal of Genetics: Applied Research, 2015
The intron located between the first and the second nucleotide of the leucine tRNA anticodon is the only representative of the group I introns in higher plants. In this work, the intron sequence of the plastid trnL gene was for the first time described in 16 legumes species and putative secondary structures of the full-length intron and its functional ...

Reconstruction of structural evolution in the trnL intron P6b loop of symbiotic Nostoc (Cyanobacteria)

Current Genetics, 2011
In this study we reconstruct the structural evolution of the hyper-variable P6b region of the group I trnLeu intron in a monophyletic group of lichen-symbiotic Nostoc strains and establish it as a useful marker in the phylogenetic analysis of these organisms.

Phylogenetic relationships among morphotypes of Caesalpinia echinata Lam. (Caesalpinioideae: Leguminosae) evidenced by trnL intron sequences

Naturwissenschaften, 2008
Caesalpinia echinata (brazilwood or Pernambuco wood) comprises a complex of three morphological leaf variants, characterized by differences in the number and size of the pinnae and leaflets, and occurring in allopatric and sympatric populations. The present study evaluates the utility of the chloroplast DNA trnL intron in a phylogenetic analysis of the

Polyphyly of the Genus Dentaria (Brassicaceae): Evidence from trnL Intron and ndhF Sequence Data

Systematic Botany, 2000
Abstract Members of the traditional genus Dentaria (Brassicaceae) comprise about twenty species disjunctly distributed in three biogeographical areas: eastern North America, western North America, and Eurasia. The group has variously been treated as a distinct genus, as a subgenus of Cardamine, or as several sections within Cardamine. Using chloroplast

A high-throughput belowground plant diversity assay using next-generation sequencing of the trnL intron

Plant and Soil, 2016
We refine and test a next-generation sequencing assay for the molecular identification and quantification of plant roots from mixed-species samples. We modified primers targeting the trnL intron to provide greater taxonomic resolution and developed an improved bioinformatics pipeline that can identify roots based on global, site-, and plot-specific ...

Chloroplast DNA analysis of Tunisian pistachio (Pistacia vera L.): Sequence variations of the intron trnL (UAA)

Scientia Horticulturae, 2015
Abstract The trnL (UAA) intron sequences of Pistacia vera ecotypes were employed to reconstruct the phylogeny and to elucidate molecular evolution. A single band of approximately 500 pb length was amplified from each cultivars. Nucleotides sequences were aligned using the ClustalW package in the Bioedit program and analyzed with MEGA program version ...
