Cytoplasmic polymorphism and evolutionary history of plum cultivars: Insights from chloroplast DNA sequence variation of trnL-trnF spacer and aggregated trnL intron & trnL-trnF spacer

open access: yesGenetics and Molecular Research, 2015
We screened for polymorphisms of the non-coding region of plastid DNA in plum trees. Sequencing data from the trnL-trnF chloroplast region were used to reveal a pattern of diversity, establish phylogenetic relationships, and test the selection pressure or evolutionary demography scenario for plastome DNA.

Phylogenetic Relationships within Apocynaceae s.l. Based on trnL Intron and trnL-F Spacer Sequences and Propagule Characters

open access: yesAnnals of the Missouri Botanical Garden, 2001
Relationships within Apocynaceae s.l. (Apocynaceae s. str., Periplocaceae, and Asclepiadaceae) were investigated by maximum parsimony analysis of morphological and molecular sequence data. Sequences of the plastid trnL intron and trnL-F spacer for 152 accessions for representatives of all major tribes were included in this study; 96% of these sequences

Experimental quantification of pollen with DNA metabarcoding using ITS1 and trnL [PDF]

open access: yesScientific Reports, 2020
AbstractAlthough the use of metabarcoding to identify taxa in DNA mixtures is widely approved, its reliability in quantifying taxon abundance is still the subject of debate. In this study we investigated the relationships between the amount of pollen grains in mock solutions and the abundance of high-throughput sequence reads and how the relationship ...

The deepest splits in Chloranthaceae as resolved by chloroplast sequences [PDF]

open access: yes, 2003
Evidence from the fossil record, comparative morphology, and molecular phylogenetic analyses indicates that Chloranthaceae are among the oldest lineages of flowering plants alive today. Their four genera (ca.

Phylogenetics of Cucumis (Cucurbitaceae) [PDF]

open access: yes, 2007
Background: Melon, Cucumis melo, and cucumber, C. sativus, are among the most widely cultivated crops worldwide. Cucumis, as traditionally conceived, is geographically centered in Africa, with C. sativus and C.

Two-Loop QCD Corrections to the Heavy-to-Light Quark Decay [PDF]

open access: yes, 2008
We present an analytic expression for the two-loop QCD corrections to the decay process b -> u W^*, where b and u are a massive and massless quark, respectively, while W^* is an off-shell charged weak boson.

Phylogeny of Miliusa (Magnoliales: Annonaceae: Malmeoideae: Miliuseae), with descriptions of two new species from Malesia [PDF]

open access: yes, 2013
The molecular phylogeny of Miliusa (Annonaceae) is reconstructed, with 27 (of ca. 50) species included, using a combination of seven plastid markers (rbcL exon, trnL intron, trnL-F spacer, matK exon, ndhF exon, psbA-trnH spacer, and ycf1 exon ...
