DNA based molecular markers allow precise, objective and rapid cultivar identification. In this study, five ISSR and two sets of fluorescence-labeled TP-M13-SSR markers were applied for discrimination of eight closely related wheat cultivars. Five ISSR primers revealed a total of 43 distinct reproducible bands, 29 (67.44%) of the 43 bands were polymorphic. The number of polymorphic bands detect...
Mango is one of the most commercially important fruit crops in tropical and subtropical regions. To increase the efficiency of breeding strategies, two EST-derived marker systems were developed in the present study using information from the mango fruit transcriptome. Using simple sequence repeats, 218 of 230 primer pairs showed stable amplification for 7 mango genotypes with amplicons ranging ...
Background: The tan spot disease of wheat caused by Pyrenophera tritici-repentis has become a major disease in most wheat growing areas worldwide. Objectives: Here we used ISSR and RAPD markers to study the genetic diversity of 34 P. tritici-repentis isolates collected from North of Iran. Materials and Methods: The leaves having the typical symptoms of tan spot disease were collected and after...
Grapevine (Vitis vinifera L.) is a clonally propagated major fruit crop. In grapevine, identification of genotypes with amplographical features is often based on mature plant characteristics that may be affected by environmental conditions. This approach lacks objectivity and reliability. Recently, molecular markers have proved to be supplementary techniques to analyze genetic diversity and exa...

Formation of the two- and six-rowed types in barley is predominantly controlled by alleles at a single locus (vrs1) which is located in long arm of chromosome 2H. This gene is a key character on the study of barley domestication and yield. Near-isogenic lines (NILs) of barley were produced from crosses between Kanto Nakate Gold (tow-rowed) and Azumamugi (six-rowed). The selected lines were used...
The goals of this investigation were to identify and evaluate the use of polymorphic microsatellite marker (PMM) analysis for molecular typing of seventeen plant pathogenic fungi. Primers for di-, tri-, and tetranucleotide loci were designed directly from the recently published genomic sequence of Mycospherlla graminicola and Fusarium graminearum. A total of 20 new microsatellite primers as eas...

Cadmium is a toxic unnecessary element for humans and plants which is easily absorbed by plants. Genetic variation in cadmium accumulation provides an opportunity for breeding programs to select genotypes with low cadmium. Due to the high cost of plant tissue analysis to determine the amount of cadmium, use of markers to make efficient selection of low cadmium accumulating genotypes is an effec...
in order to identify the sex marker in mahisefied, rutilus frisii kutum, samples from 5 male and 5 female fish were collected from the south caspian sea. polymerase chain reaction random amplified polymorphic dna (pcr-rapd) was performed using 124 primer sets. all bands were numbered using 1 and 0 scores corresponding to the presence or absence of bands, respectively and data were analyzed usin...
