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 ...

Development of Cytoplasmatic SSR-Markers for Population Genetic Studies of the Siberian Stone Pine (Pinus Sibirica Du Tour) [PDF]
Сибирский лесной журнал, 2014 Three chloroplast and one mitochondrial DNA markers were developed and used for genotyping of 60 trees in two populations of the Siberian stone pine (Pinus sibirica Du Tour).

Mitochondrial DNA. Part B. Resources, 2018 We determined the complete chloroplast DNA sequence of Artemisia hallaisanensis Nakai, an endemic herbal species distributed on Jeju Island, Korea. The chloroplast DNA is 151,015 bp in length and encodes 4 rRNA, 30 tRNA, and 80 protein-coding genes ...

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 ...

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

A functional RNase P protein subunit of bacterial origin in some eukaryotes [PDF]
, 2011 RNase P catalyzes 5′-maturation of tRNAs. While bacterial RNase P comprises an RNA catalyst and a protein cofactor, the eukaryotic (nuclear) variant contains an RNA and up to ten proteins, all unrelated to the bacterial protein.

FEBS Open Bio, EarlyView.Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Chloroplast DNA Diversity of Oak Species in Eastern Romania
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2010 The chloroplast DNA of 34 sessile oak (Quercus petraea) and 27 pedunculate oak (Q. robur) populations covering the entire natural distribution of the two oak species in Eastern Romania was investigated using four large regions of the chloroplast genome ...
