Recognition of genetic reserves and desirable genes is the basis of breeding programs. So far, in Iran, due to the lack of recognition of genetic resources, a considerable breeding program has not been done on native plants. The study of the genetic diversity of violets as a native plant with ornamental and medicinal uses is the great importance in advancing the breeding goals of this plant. So...

Expressed sequence tags simple sequence repeats (EST-SSRs) are important sources for investigation of genetic diversity and molecular marker development. Similar to genomic SSRs, the EST-SSRs are useful markers for many applications in genetics and plant breeding such as genetic diversity analysis, molecular mapping and cross-transferability across related species and genera. In spite of low po...

genetic diversity of six populations of bartail flathead (platycephalus indicus linnaeus, 1758) was investigated using amplified fragment length polymorphism (aflp). a total of 118 reproducible bands amplified with ten aflp primer combinations were obtained from 42 fishes that were collected from six different locations in the northern part of the persian gulf. the percentage of polymorphic ban...

in this study, genetic diversity of 20 wheat genotypes was evaluated using 126 simple sequence repeats (ssr) alleles, covering all three wheat genomes. a total of 1557 allelic variants were detected for 126 ssr loci. the number of alleles per locus ranged from 4 to 19 and the allelic polymorphism information content (pic) varied from 0.66 (xgwm429) to 0.94 (xgwm212 and xgwm515). the high­est po...

genetic variations within the species of agropyron desertorum and 2 varieties of a. cristatum subsp. pectinatum var. imbricatum and a. cristatum subsp. pectinatum var. pectinatum were studied using morphological traits and total protein profiles (with sodium dodecylsulphate polyacrylamide gel electrophoresis). an experiment was conducted in research institute of forests and rangelands (2012-201...

since crosses of lines with suitable genetic distance produce excellent hybrids, the identification of genetic diversity between zea mays l. inbred lines in hybrid maize breeding programs has a high priority. a total of 27 inbred lines plus b73 and mo17 (sc704 parents) were evaluated by 15 inter-simple sequence repeat (issr) primers. inbreds were selected randomly from inbred lines from the agr...

background: fasciola hepatica and f. gigantica are the causative agents of fasciolosis in domestic animals and humans. based on the morphometric criteria, differential diagnosis between them is problematic. in addition, intermediate forms of fasciola have been found in iran, which makes the differentiation more difficult. the aim of the present study was to provide molecular evidence for the ex...

the archaeological evidence suggests that iran has been one of the first origins of sheep domestication in the world. this study aims to investigate the genetic diversity of indigenous iranian sheep breeds using mitochondrial dna (mtdna) and to explore the evolutionary history of sheep domestication in iran. single nucleotide polymorphism (snp) markers in the control region of mtdna were used t...
