Previous studies of Veronica and related genera were weakly supported by molecular and paraphyletic taxa. Here, we report the complete chloroplast genome sequence of Veronica nakaiana and the related species Veronica persica and Veronicastrum sibiricum. The chloroplast genome length of V. nakaiana, V. persica, and V. sibiricum ranged from 150,198 bp to 152,930 bp. A total of 112 genes comprisin...

The compartmentalization of eukaryotic cells requires that newly synthesized proteins be targeted to the compartments in which they function. In chloroplasts, a few thousand proteins function in photosynthesis, expression of the chloroplast genome, and other processes. Most chloroplast proteins are synthesized in the cytoplasm, imported, and then targeted to a specific chloroplast compartment. ...

The unequivocal documentation fintrogression can be a difficult task because alternative hypotheses, uch as convergence or joint retention of the ancestral condition, are difficult todisprove. Similarly, the direction of introgression between two species can often be inferred, but more rarely proven. Molecular markers offer perhaps the best means of demonstrating introgression, because they are...

Two fundamental questions on how invasive species are able to rapidly colonize novel habitat have emerged. One asks whether a negative correlation exists between the genetic diversity of invasive populations and their geographic distance from the origin of introduction. The other is whether selection on the chloroplast genome is important driver of adaptation to novel soil environments. Here, w...

During the past decade, there has been a rapid increase in our understanding of plastid genome organization and evolution due to the availability of many new completely sequenced genomes. There are 45 complete genomes published and ongoing projects are likely to increase this sampling to nearly 200 genomes during the next 5 years. Several groups of researchers including ours have been developin...

DNA supercoiling in the chloroplast of the unicellular green alga Chlamydomonas reinhardtii was found to change with a diurnal rhythm in cells growing in alternating 12-h dark-12-h light periods. Highest and lowest DNA superhelicities occurred at the beginning and towards the end of the 12-h light periods, respectively. The fluctuations in DNA supercoiling occurred concurrently and in the same ...

BACKGROUND The study of plant populations is greatly facilitated by the deployment of chloroplast DNA markers. Asymmetric inheritance, lower effective population sizes and perceived lower mutation rates indicate that the chloroplast genome may have different patterns of genetic diversity compared to nuclear genomes. Convenient assays that would allow intraspecific chloroplast variability to be ...

Nelumbo nucifera is an evolutionary relic from the Late Cretaceous period. Sequencing the N. nucifera mitochondrial genome is important for elucidating the evolutionary characteristics of basal eudicots. Here, the N. nucifera mitochondrial genome was sequenced using single molecule real-time sequencing technology (SMRT), and the mitochondrial genome map was constructed after de novo assembly an...

Boswellia sacra (Burseraceae), a keystone endemic species, is famous for the production of fragrant oleo-gum resin. However, the genetic make-up especially the genomic information about chloroplast is still unknown. Here, we described for the first time the chloroplast (cp) genome of B. sacra. The complete cp sequence revealed a circular genome of 160,543 bp size with 37.61% GC content. The cp ...
