1 The indigenous oak species (Quercus spp.) of the Upper Rhine Valley have migrated to their 2 current distribution range in the area after the transition to the Holocene interglacial. Since 3 post-glacial recolonization, they have been subjected to ecological changes and human 4 impact. By using chloroplast microsatellite markers (cpSSRs), we provide detailed 5 phylogeographic information and ...
Hippophae tibetana is a small, dioecious wind-pollinated shrub endemic to the Tibetan-Qinghai Plateau. It is one of the shrubs that occur at very high elevations (5250 m a.s.l.). The Himalayan mountains provides a significant geographical barrier to the Qinghai-Tibetan Plateau, dividing the Himalayan area into two regions with Nepal to the south and Tibet to the north. There is no information o...
Based on morphological and molecular evidence, two new species of Silene are recognized described here, S. penduliflora F.Jafari, Keshavarzi & Doostm. sp. nov. thyrsiantha Mirtadz. The newly discovered distributed in the central southeastern parts Iran, growing rocky habitats. Relationships among these their close relatives demonstrated using nrDNA ITS cpDNA rps16 phylogenies. ghahremaninej...
Pongamia pinnata (syn. Millettia pinnata) is a novel, fast-growing arboreal legume that bears prolific quantities of oil-rich seeds suitable for the production of biodiesel and aviation biofuel. Here, we have used Illumina® 'Second Generation DNA Sequencing (2GS)' and a new short-read de novo assembler, SaSSY, to assemble and annotate the Pongamia chloroplast (152,968 bp; cpDNA) and mitochondri...
The systematic utility of sequences from a non-coding region of chloroplast DNA (cpDNA) between psbA and trnH (6v6) was examined by assessing phylogenetic relationships in subtribe Sonchinae (Asteraceae: Lactuceae). Primers constructed against highly conserved regions of tRNA genes were used for PCR amplification and sequencing. The psbA-trnH intergenic spacer contains several insertions and de...
We investigate patterns of genetic variation along an east-west transect of Central European populations of Linum flavum and interpret the Quaternary history of its peripheral populations, especially those at the westernmost isolated range edge, discussing their migrations and possible relict status. We defined our peripheral transect across three study regions from Central Hungary, eastern Aus...
Assessment of phylogenetic relationships is an important component of any successful crop improvement programme, as wild relatives of the crop species often carry agronomically beneficial traits. Since its domestication in East Africa, Eleusine coracana (2n = 4x = 36), a species belonging to the genus Eleusine (x = 8, 9, 10), has held a prominent place in the semi-arid regions of India, Nepal a...
The beech species Fagus hayatae is an important relict tree species in subtropical China, whose biogeographical patterns may reflect floral responses to climate change in this region during the Quaternary. Previous studies have revealed phylogeography for three of the four Fagus species in China, but study on F. hayatae, the most sparsely distributed of these species, is still lacking. Here, mo...
The eastern Asia-North America disjunction is one of the most interesting biogeographical patterns, but its formation is still in much debate. Here nucleotide sequences of five cpDNA regions, nrDNA ITS and two low-copy nuclear genes (LEAFY, 4CL) were employed to reconstruct the phylogeny and to explore the historical biogeography of Thuja, a typical eastern Asia-North America disjunct genus. Hi...
Pseudo-nitzschia is a species-rich genus where many species can induce harmful algae blooms (HABs) associated with the toxin domoic acid (DA) production. Despite importance of to coastal environments, their genomic information rather limited, hindering research on biodiversity and evolutionary analysis. In this study, we report full-length chloroplast genomes (cpDNAs) nine Pseudo‐nitzschia , am...
