Third-codon transversion rate-based _Nymphaea_ basal angiosperm phylogeny -- concordance with developmental evidence [PDF]

, 2007
Flowering plants (angiosperms) appeared on Earth rather suddenly approximately 130 million years ago and underwent a massive expansion in the subsequent 10-12 million years.

Chloroplast genome variation and phylogenetic relationships of Atractylodes species

BMC Genomics, 2020
Atractylodes DC is the basic original plant of the widely used herbal medicines “Baizhu” and “Cangzhu” and an endemic genus in East Asia. Species within the genus have minor morphological differences, and the universal DNA barcodes cannot clearly ...

Phylogenomic Analysis and Dynamic Evolution of Chloroplast Genomes in Salicaceae

Frontiers in Plant Science, 2017
Chloroplast genomes of plants are highly conserved in both gene order and gene content. Analysis of the whole chloroplast genome is known to provide much more informative DNA sites and thus generates high resolution for plant phylogenies. Here, we report

Phylogeny of Prokaryotes and Chloroplasts Revealed by a Simple Composition Approach on All Protein Sequences from Complete Genomes Without Sequence Alignment [PDF]

, 2005
The complete genomes of living organisms have provided much information on their phylogenetic relationships. Similarly, the complete genomes of chloroplasts have helped to resolve the evolution of this organelle in photosynthetic eukaryotes.

History of chloroplast genomics [PDF]

Photosynthesis Research, 2003
The presence of chloroplast DNA was established in 1963. With the development of recombinant DNA technologies, chloroplast DNA was selected as one of the first candidates for genome sequencing. The first physical map was reported for maize chloroplasts in 1976.

Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content. [PDF]

, 2016
Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution ...

Comparative chloroplast genome analyses of Avena: insights into evolutionary dynamics and phylogeny

BMC Plant Biology, 2020
Oat (Avena sativa L.) is a recognized health-food, and the contributions of its different candidate A-genome progenitor species remain inconclusive.

Characterization of the complete chloroplast genome of Cycas hongheensis (Cycadaceae), an endemic species in the red river region of China

Mitochondrial DNA. Part B. Resources, 2021
In this study, we determined the complete chloroplast genome of Cycas hongheensis (Cycadaceae), one of the first-class protected plants in China. The chloroplast genome is 162,048 bp in length with 133 genes, including 87 protein-coding genes, eight ...

The use of chloroplast genome sequences to solve phylogenetic incongruences in Polystachya Hook (Orchidaceae Juss) [PDF]

, 2018
Background: Current evidence suggests that for more robust estimates of species tree and divergence times, several unlinked genes are required. However, most phylogenetic trees for non-model organisms are based on single sequences or just a few regions ...
