The distribution of Nepenthes mirabilis ranges from Northeast (NE) to South (S) Thailand. Eleven individuals from NE, S and Suen Jatujak market in Bangkok, Central (C) Thailand, were collected and divided into four populations according to their geographical areas. These four populations were analyzed to determine a genetic diversity profile using thirteen inter-simple sequence repeat markers. The...
Family Apocynaceae is an economically important family grown as ornamental plants and many wild species have medicinal uses as well. The aim of the present study was to understand the level and pattern of genetic variability among the selected individuals of Apocynaceae. For this purpose, three species of different genera of Apocynaceae, Thevetia peruviana, Alstonia scholaris and Catharanthus roseus...
Post-glacial survival, potential migration routes, genetic diversity and phylogeography of the boreal moss species Rhytidium rugosum have been studied. This species is considered to be one of glacial relics of the wide but scattered Holarctic range. According to molecular data sampling from the selected European, American and Asian populations high genetic diversity of this species is present, even...
PCR amplification techniques viz., repetitive DNA element PCR (REP-PCR), short tandemly repeated repetitive PCR (STRR-PCR) and arbitrarily primed PCR (RAPD-PCR) were used for the taxonomic discrimination among the strains of the unicellular cyanobacterium Synechococcus elongatus collected across the coastal regions of the Indian subcontinent. These strains showed similar phenotypic and genotypic characteristics...
Relics of Malva alcea are found in Central and Western Europe. A similar taxon, M. excisa, is native to the eastern parts of Europe. According to selected sources, the geographical range boundary of the above taxa intersects Poland. Taxonomic research relying on key morphological features (the depth of corolla petal incisions and the type of hairs covering the stem) did not clearly validate the distinctness...
Ranunculus cabrerensis is an endemic and endangered species of the Northwestern Iberian Peninsula. The molecular markers AFLP and ISSR were used to investigate the genetic diversity and population structure of four populations across its known distribution. Fifteen selective primer combinations of AFLP and seventeen ISSR primer combinations produced a total of 2830 and 103 unambiguously repeatable...
Asian swamp eel is a highly commercial fish, primarily for China and other Asian countries. The aim of this paper is to evaluate the genetic diversity of wild and cultured samples of Asian swamp eel Monopterus albus using ISSR markers. A total of 129 individuals belonging to three wild samples, Xiantao (XT), Huanggang (HG), Xinyang (XY) and three cultured samples, Wuhan (WH), Jingzhou (JZ) and Nanjing...
Pinus mugo (dwarf mountain pine) is an important component of European mountain ecosystems. However, little is known about the present genetic structure and population differentiation of this species at the DNA level, possibly due to a lack of nuclear microsatellite markers (SSR) developed for Pinus mugo. Therefore in this study we transferred microsatellite markers originally developed for Pinus sylvestris...
We investigated informativeness and effectiveness of different marker types (ISSR, IRAP, REMAP, RGAP and LP-PCR that employ primers based on the conservative sequences of abiotic stress response genes) to study genetic diversity of Iris pumila L. By the number of amplicons per primer, number of polymorphic amplicons per primer and resolving power index (Rp), ISSR-markers were the most efficient followed...
Genetic diversity and phylogenetic analyses of 24 species, representing nine sections of the genus Galium (Rubiaceae), have been made using the Inter Simple Sequence Repeats (ISSR), Randomly Amplified Polymorphic DNA (RAPD), and combined ISSR and RAPD markers. Four ISSR primers and three RAPD primers generated 250 polymorphic amplified fragments. The results of this study showed that the level of...
To investigate the genetic diversity and phylogenetic relationships between polyploid Leymus and related diploid species of the Triticeae tribe, inter-simple sequence repeats (ISSR) markers was used to analyze 41 Leymus accessions representing 22 species and 2 subspecies, together with Pseudoroegneria stipifolia (St), Psathyrostachys fragilis (Ns), Australopyrum retrofractum (W), Hordeum bogdanii,...
Iran, as a part of Fertile Crescent, is within the center of diversity and origin of the Triticum L. from Poaceae Barnhart (Gramineae A. L. de Jussieu) family. This study concerns the genetic diversity and inter-relationships analyses of 89 accessions of diploid Triticum (2n = 2x = 14) species including T. monococcum, T. boeoticum subsp. boeoticum, T. boeoticum subsp. thaoudar and T. urartu belong...
Chinese prickly ash, belonging to the genus Zanthoxylum L., has been one of the most important commercially-exploited plants for its alimentary, industrial and medicinal applications. However, the breeding and promotion of Chinese prickly ash have been severely restricted due to its confusing classification. Therefore, we assessed genetic diversity and phylogenetic relationship among 45 Chinese prickly...
Thymus daenensis subsp. daenensis is an aromatic medicinal plant endemic to Iran and generally grows in high altitudes in Zagros Mountains range. Molecular markers provide valuable information about relative genetic relationships for facilitate breeding programs. Here, we used SRAP markers to estimate the genetic diversity of 79 T. daenensis accessions from 16 regions in Iran, located at extremes...
Stachys L. (Lamiaceae) exhibits a great range of variation with cosmopolitan distribution. An area extremely rich in taxa including 34 species has been introduced in Iran. This study documents the genetic diversity and morphological variations of 48 accessions from fifteen Stachys species and two subspecies belonging to six sections. All of the specimens were collected from natural habitats in Zagros...
Flax (Linum usitatissimum L.) is the third largest natural fiber crop in the world. The flax genome shows environmentally induced heritable genomic changes. The activation of transposable elements has been proposed and identified as the mechanism behind this genotypic plasticity. Transposable elements, particularly the retrotransposons, generates genomic diversity by replication which makes them an...
To investigate the Ns genome donor of Leymus and to elucidate the origin of Xm genome of Leymus, Random Amplified Polymorphic DNA (RAPD) markers were used to analyze 13 Leymus accessions, together with 14 taxa from related Triticeae genera. A total of 156 clear and reproducible DNA fragments were amplified by 24 RAPD primers, among which 154 fragments (98.72%) were found to be polymorphic. The main...
Desert annual plant species are valuable pasture forage and sources for restoration of degraded pastures. Examining the impact of environmental stresses on genetic diversity and population structure can identify species populations suitable for habitat restoration. We examined allozyme diversity and population structure of two annual species, haloxerophyte Salsola incanescens and xero-halophyte S. paulsenii...
Carniolan honeybee (Apis mellifera carnica) is considered an endangered subspecies of Apis mellifera in Slovakia due to its illegal crossbreeding with allochthonous subspecies. Despite more than a century-long tradition of Slovak beekeeping, genetic research of Slovak honeybees has not yet been done. The aim of our study was to develop a molecular approach to characterize Carniolan honeybee population...
Lettuce (Lactuca sativa L.), a leafy vegetable belonging to Asteraceae family, possesses sedative-hypnotic, anti-convulsant, anti-inflammatory, antinociceptive, anticancer, and antioxidant properties. Currently, only a few microsatellite markers have been developed from lettuce, which hindered the genetic research. In the present study, EST-SSRs were developed and characterized from 81,518 expressed...
