The Complete Chloroplast Genome Sequences of Three Veroniceae Species (Plantaginaceae): Comparative Analysis and Highly Divergent Regions
نویسندگان
چکیده
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 comprising 79 protein coding genes, 29 tRNA genes, and 4 rRNA genes were observed in three chloroplast genomes. The total number of SSRs was 48, 51, and 53 in V. nakaiana, V. persica, and V. sibiricum, respectively. Two SSRs (10 bp of AT and 12 bp of AATA) were observed in the same regions (rpoC2 and ndhD) in three chloroplast genomes. A comparison of coding genes and non-coding regions between V. nakaiana and V. persica revealed divergent sites, with the greatest variation occurring petD-rpoA region. The complete chloroplast genome sequence information regarding the three Veroniceae will be helpful for elucidating Veroniceae phylogenetic relationships.

Comparative bioinformatics analysis of a wild diploid Gossypium with two cultivated allotetraploid species
Background: Gossypium thurberi is a wild diploid species that has been used to improve cultivated allotetraploid cotton. G. thurberi belongs to D genome, which is an important wild bio-source for the cotton breeding and genetic research. To a certain degree, chloroplast DNA sequence information are a versatile tool for species identification and phylogenetic implications in plants. Different ch...
متن کاملThe Complete Chloroplast Genome Sequences of Fritillaria ussuriensis Maxim. and Fritillaria cirrhosa D. Don, and Comparative Analysis with Other Fritillaria Species.
The genus Fritillaria belongs to the widely distributed Liliaceae. The bulbs of Fritillaria, F. ussuriensis and F. cirrhosa are valuable herbaceous medicinal ingredients. However, they are still used indiscriminately in herbal medicine. Identification and molecular phylogenic analysis of Fritillaria species are therefore required. Here, we report the complete chloroplast (CP) genome sequences o...

متن کاملTesting the Hypothesis of Allopolyploidy in the Origin of Penstemon azureus (Plantaginaceae)
Polyploidy plays a major role in the evolution of angiosperms with multiple paleopolyploid events having been suggested making it plausible that all angiosperms have a polyploid event in their history. Polyploidy can arise by genome duplication within a species (i.e., autopolyploidy), or whole genome duplication coupled with hybridization (i.e., allopolyploidy). Penstemon subsection Saccanthera...
