Dipterocarpoideae, the largest sub-family of well-known plant family Dipterocarpaceae, dominates in South Asian rain forests. Although several previous studies addressed the phylogeny of the Dipterocarpaceae family, relationships among many of its genera from the Dipterocarpoideae sub-family are still not well understood. In particular, little is known about the relationships of the genera Vate...

Geographic patterns of genetic variation in chlorolast (cpDNA) and nuclear ribosomal (nrDNA) DNA were examined to test the hypothesis of hybridization between Juniperus osteosperma and Juniperus occidentalis in the Great Basin of western Nevada. Noncoding DNA from the trnL-trnF intergenic spacer and the trnL intron of the chloroplast genome was sequenced from seven populations of J. osteosperma...

Currently, the information on the gene pool of silver fir (Abies alba Mill.) at the northeastern edge of its distribution in Poland is scarce and insufficient. Using the advantage provided by markers with different modes of inheritance, a hypothesis that gene flow via both seeds and pollen contributed to the genetic structure across the entire analyzed region was investigated. The geographic di...

The effects of rapid, recent uplift of the Hengduan Mountains on evolution and diversification of young floristic lineages still remain unclear. Here, we investigate diversification of three closely related Saxifraga species with a distribution restricted to the Hengduan Mountains (HM) and southern Tibet, and comment on their taxonomy based on molecular evidence. Three chloroplast DNA fragments...

With the completion of the first gymnosperm mitochondrial genome (mtDNA) from Cycas taitungensis and the availability of more mtDNA taxa in the past 5 years, we have conducted a systematic analysis of DNA transfer from chloroplast genomes (cpDNAs) to mtDNAs (mtpts) in 11 plants, including 2 algae, 1 liverwort, 1 moss, 1 gymnosperm, 3 monocots, and 3 eudicots. By using shared gene order and boun...

Chloroplasts are important organelles in a plant cell, having their own DNA (cpDNA), transmitted only through the female line, and performing function of photosynthesis. The determination chloroplast is interest study genetic diversity phylogeny potatoes, cytoplasmic sterility, as well for applications biotechnology engineering. Here, we reconstructed complete plastomes 15 S. tuberosum potato c...

Recolonization of Europe by forest tree species after the last glaciation is well documented in the fossil pollen record. This spread may have been achieved at low densities by rare events of long-distance dispersal, rather than by a compact wave of advance, generating a patchy genetic structure through founder effects. In long-lived oak species, this structure could still be discernible by usi...

The Chlorophyceae, an advanced class of chlorophyte green algae, comprises five lineages that form two major clades (Chlamydomonadales + Sphaeropleales and Oedogoniales + Chaetopeltidales + Chaetophorales). The four complete chloroplast DNA (cpDNA) sequences currently available for chlorophyceans uncovered an extraordinarily fluid genome architecture as well as many structural features distingu...

Simple sequence repeats (SSRs) are present abundantly in most eukaryotic genomes. They affect several cellular processes like chromatin organization, regulation of gene activity, DNA repair, DNA recombination, etc. Though considerable data exists on using nuclear SSRs to infer phylogenetic relationships, the potential of chloroplast microsatellites (cpSSR), in this regard, remains largely unexp...

The Qinghai-Tibetan Plateau (QTP) has become one of the hotspots for phylogeographical studies due to its high species diversity. However, most previous studies have focused on the effects of the Quaternary glaciations on phylogeographical structures and the locations of glacial refugia, and little is known about the effects of the aridization of interior Asia on plant population structure and ...
