molecular markers in plants: concepts and applications
نویسندگان
چکیده
genetic markers are one of the advances which have occured in the genomics era. among genetic markers, molecular markers mainly because of their abundance, are the most widely used them. development of molecular markers has greatly altered genetics and plant breeding. genetic markers indicate the genetic differences between different organs or species. some studies which were conducted during the last decade of the 20th century reported numerous dna markers that have been utilized in plant breeding programs. apart from the application of molecular markers in the construction of linkage maps, they have numerous applications in plant breeding such as assessing the genetic variations within cultivars and germplasms. the most interesting application of molecular markers is marker-assisted selection (mas). suitable dna markers should be polymorphic in the dna level and can be expressed in all tissues, organs, and various developmental stages. compared with traditional breeding programs, molecular markers can increase the efficiency and effectiveness of breeding programs. in this study, the most distinctive applications of molecular markers in the breeding studies are described.

Neuroblastoma, one of the common malignant childhood tumors, arises from neuroblast cells derived from theneural crest and destined for the adrenal medulla and the sympathetic nervous system and shows remarkable biologicalheterogeneity, resulting in favorable or unfavorable outcomes. Some tumors make rapid progress with a fataloutcome. In other instances, the tumors regress spontaneously in inf...
متن کاملApplications of molecular markers in strawberry
This review examines current and potential applications of molecular markers in strawberry (Fragaria spp.). The most prevalent uses of markers in strawberry are for analyses of genetic diversity, genetic mapping, and cultivar identification. Cultivar identification is by far the most important use of markers to date for the protection of intellectual property as well as to confirm the identity ...

In the 1950s we found that all the sites of a well-defined carbon environment of the ketone function contribute to the expression of its properties. This justified a new description of ketones with a topological code. The ketone molecular structure was handled as a simple graph corresponding to an ordered rooted tree. We generalized this treatment to achieve a new, original nomenclature called ...
