The Role of Molecular Marker in Development of Plant Genetic Resources

Abstract:

Plants are fundamental to life, being the basis of our food production and an essential part of the global ecosystem on which life on earth depends. Plant genetic resources include primitive forms of cultivated plant species and landraces, modern cultivars, breeding lines and genetic stocks, weedy types and related wild species, which provide the building blocks that, allow classical plant breeders and biotechnologists to develop new commercial varieties and other biological products. Detection and analysis of genetic variation can help us to understand the molecular basis of various biological phenomena in plants. Molecular markers for the detection and exploitation of DNA polymorphism is one of the most significant developments in the field of molecular genetics. The presence of various types of molecular markers, and differences in their principles, methodologies, and applications require careful consideration in choosing one or more of such methods. This article describes the advances of molecular marker in present, introduces the molecular basis in development of plant genetic resources and perspectives the important role of molecular marker in development of plant genetic resources in the future.
