Natural hybridization and introgression is recorded between the newt species Triturus vulgaris and T. montandoni in Slovakia. To confirm a hybrid status of two putative hybrids, morphological and Randomly Amplified Polymorphic DNA (RAPD) markers specific for T. vulgaris and T. montandoni were used. The individuals found in Zbojská (Veporské vrchy Mts, Slovakia; analyzed morphologically and genetically)...
Collected from Chinese mainland, 25 samples of Toona sinensis seed were planted in a standard garden. Three years later, samples were analyzed with random amplified polymorphic DNA (RAPD) and isoenzymes variants of cytochrome oxidase and peroxidases. Results of RAPD and isoenzymes variants were analyzed with software POPGENE32 and SPSS10.0 respectively. Phylogenetic trees were calculated from the...
In the present work we used three molecular techniques (allozymes, RAPDs and mtDNA RFLPs) in order to study the genetic structure of three commercial marine species (Mullus surmuletus, Mullus barbatus, and Pagellus erythrinus). Each species was sampled from three locations within the Gulf of Pagasitikos, Greece and from two neighbouring locations outside the Gulf (Trikeri and Alonissos). Values of...
Eryngium L. species growing in Syria were characterized using morphological, geographical and molecular analyses (IRAP and RAPD). Eight Eryngium L. species have been determined to exist in Syria. E. glomeratum, E. campestre and E. falcatum were found to grow in the mountain regions. E. creticum and E. desertorum were found to grow in variant environments: mountains, semidesert and saline environments,...
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...
Conservation of identified germplasm is an important component for efficient and effective management of plant genetic resources. Since Chlorophytum species are important medicinal plants, studies were carried out for identification and establish genetic relationships in three species of Chlorophytum and two high yielding genotypes of Chlorophtum borivilianum using RAPD markers. Out of one hundred...
Leech taxonomy is based on unstable morphological characters. The overall level of genetic variability and species differentiation is unknown. Using the RAPD assays genetic diversities and genetic similarities were estimated in twelve species collected in North-Eastern Poland and representing three families and five subfamilies. Ten primers revealed 204 reproducible bands. Genetic diversities varied...
A highly efficient protocol for in vitro regeneration of an indigenous, endangered medicinal plant Celastrus paniculatus was achieved using nodal explants. Murashige and Skoog (MS) basal medium supplemented with 0.5 mg/L 6-benzylaminopurine (BAP) and 0.1 mg/L naphthaleneacetic acid (NAA) showed maximum percentage of shoot multiplication (83.4%) with 8.2 shoots/explants. Maximum rooting of 73.3% with...
Trees of Aesculus sp. are often present in European landscapes. Common horse chestnut and red horse chestnut are seriously damaged by the fungus Erysiphe flexuosa as well as the pest Cameraria ohridella. Both pathogen and pest have spread throughout Europe. A genetic background of trees resistance still remains unknown. The present study was undertaken to estimate genetic variation of A. hippocastanum...
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...
Thymus persicus (Ronniger ex Rech. f.) Jalas is a valuable and endangered natural source of antitumor pentacyclic triterpenoids, i.e., betulinic acid, oleanolic acid and ursolic acid, which grows in northwest Iran. As the plant has a low propagation rate in nature, a suitable method for in vitro-propagation is needed. With the aim of identifying a suitable system for regenerating T. persicus via...
Fluorescent Pseudomonas (FP) is an intrinsic group of plant growth promoting rhizobacteria (PGPR) which also has the potential to control phytopathogens. In the present study sixteen FP isolates were subjected to siderophore production and siderotyping. Four DNA finger printing analysis markers (RAPD, ERIC, BOX A1R, REP and GTG5) were used to assess their genetic diversity through DNA finger printing...
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...
