UNLABELLED PREMISE OF THE STUDY Phylogeographical analyses of Dyckia (Bromeliaceae) suffer from low levels of sequence variation. Plastid microsatellite markers were developed to achieve a better-resolved genus-wide plastid genealogy of Dyckia. • METHODS AND RESULTS Approximately 84% of the D. marnier-lapostollei plastome was sequenced using 454 technology. Flanking primer pairs were desig...
Sampling was done using 90 post larvae which were produced by reproduction of some broodstocks of Fenneropenaeus indicus in one day and reared in the same situation for 4 months. Samples were divided into 3 groups: high, medium and low growth (based on weight and length). Genomic DNA was extracted from muscle tissue using the phenol-chloroform method. The polymerase chain reaction (PCR) was car...
The genetic distance of 11 cotton genotypes varying in heat tolerance was studied using RAPD markers. Fifty-three random decamer primers were used for the estimation of genetic distance. Among the 53 RAPD primers, which were custom synthesized by GeneLink Inc., UK, 32 were polymorphic and 21 were monomorphic. The 32 polymorphic primers produced 273 fragments, with a mean of 8.3 fragments per pr...
Background and purpose: Due to the high annual birth rate of thalassemia major in our country, its prevention by prenatal diagnosis is of important priority. Gene mutation remains unknown in 10-20% of thalassemia trait people in Iran. In these cases, linkage analysis using polymorphic sites which are located near or within the gene is necessary to follow the mutant or the normal chromosome. Ssp...
the present research was conducted to explore the effect of employing two language teaching approaches, i.e. schema-based instruction (sbi) and translation-based instruction (tbi), on vocabulary knowledge, structure and reading comprehension ability of forty one female students learning english in grade one senior high school in rivash, kuhsorkh, iran. while sbi focuses on schemata, i.e. words ...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
Most bacteria swim through fluids by rotating helical flagella which can take one of 12 distinct polymorphic shapes, the most common of which is the normal form used during forward swimming runs. To shed light on the prevalence of the normal form in locomotion, we gather all available experimental measurements of the various polymorphic forms and compute their intrinsic hydrodynamic efficiencie...
Urtica dioica is an important medicinal plant which is widely distributed in Mazandaran province (North of Iran). In this study for the first time Amplified Fragment Length Polymorphism (AFLP) and Inter-simple Sequence Repeat (ISSR) markers were used for detection of genetic polymorphism in Mazandaran nettle. Ten AFLP primer combinations and seventeen ISSR markers were utilized. AFLP produced 830...
nowadays, technical terminology translation plays an important role in human life. specific groups of people all over the world refer to learn these terminologies in order to be familiar with a subject and improve their knowledge in that domain. on the other hand, saving the technical translation equivalent is a particularly salient challenge for technical translators. the present study was con...
Identification of AFLP markers associated with flowering time and ornamental traits in Chrysanthemum
Flowering period and longevity play important roles in determining the quality of commercial flowers. Marker-trait associations for eight flowering and 12 ornamental traits have been studied using a GLM and MLM analysis with a set of 2099 AFLP polymorphic markers in Chrysanthemum. The GLM model identified 453 markers for phenotypic traits whereas the MLM association analysis model revealed a t...
