Molecular Markers in Wheat

چکیده
The progress made in DNA markers technology has been tremendous and exciting. DNA markers have provided valuable tools in various analysis ranging from polygenetic analysis to the positional cloning of genes. The development of high density molecular maps which has been facilitated by the PCR-based markers have made the mapping of almost any trait possible. The size and structure of the wheat genome makes it one of the most complex crop species for genetic analysis. The development of molecular technique for genetic analysis, in particular the use of molecular markers to monitor DNA sequence variation between varieties, and races, and wild relatives of wheat and related grass species, has led to a dramatic expansion in our understanding the structure and behavior of wheat genome.

Genetic Diversity of Bread Wheat (Triticum aestivum L.) Genotypes Using RAPD and ISSR Molecular Markers
The importance of grain cultivation especially wheat is obvious in terms of providing human and animal food and its impact on the economy of human societies. The reduction of genetic diversity in cultivars prevents increasing yields in line with rising demand and consumption. Therefore, it is necessary to improve the compatibility of them and increase their genetic extent. In the current, the g...
متن کاملAssessment of genetic diversity and identification of SSR markers associated with grain iron content in Iranian prevalent wheat genotypes
Iron is one of the most important nutrients in the human diet. According to the high consumption of staple foods such as wheat, the deficiency of iron in these crops would lead to nutritional disorders and related complications. To identify microsatellite markers associated with wheat grain iron content,38Iranian prevalent wheat genotypes were assessed using 30 pairs of genomic and EST microsat...

Collection and conservation of germplasm, particularly for landraces of important agronomically species and organizing their information, cause to continuity of their usefulness and reduce the risk of their genetic erosion. In this experiment, 10 Iranian wheat landraces along with the Chinese Spring cultivar, as control, were used to assess inter and intra populations variation by using ISSR mo...
متن کاملEfficiency of anchored and non-anchored ISSR markers to estimate genetic diversity among bread wheat cultivars
DNA markers are integrally connected to the success of molecular breeding and are fundamentally required by breeders to be able to, a. identify new gene sources in the available biodiversity, b. select parents in order to increase heterosis, c. decrease the number of backcross generations for gene introgression breeding programs, and d. carry out marker-assisted selection (MAS). The present re...
متن کاملPCR-based markers for identification of some allelic variation at Glu-1 and Glu-3 loci in common wheat
Marker assisted selection (MAS) is a tool for breeding, screening, and genetic characterization of germplasm. Allelic variation of both high and low molecular weight glutenin subunits (HMW/LMW-GS) is associated with the rheological properties of wheat flour. In this study, we investigated glutenin pattern using SDS-PAGE and their PCR based on DNA markers in 60 advanced wheat lines and cultivars...
متن کاملTransferability of barley microsatellite markers for assessing genetic relationships of wheat wild relatives of Triticum and Aegilops genera
Comparative genomics has revealed a high degree of collinearity between related species, which allows transferability of interspecies and intergenus markers. The aim of this study was to examine the transferability of barley microsatellite markers among species of Triticum and Aegilops genus for determination of their genetic relationships. The experiments was carried out in faculty of agricu...
