Study of Plant Genetic Variation through Molecular Markers: An Overview

This article refers to viewing the role of molecular markers during analyzing genome plants and their importance in plant biotechnology. In recent years, we observed techniques programs for improving breeding preserving genetic resources has been observed, biochemical indicators which represent basic material through determining diversity between genotypes it is never affected by external surrounding conditions as always phenotype features. Molecular DNA have widely applied answer a range questions related taxonomy, evolution, population genetics, diversity, well monitoring trade food products , addition its having studying gene expression mapping, studies species evolution providing fast accurate results. this work, advantages limitations sciences such as: RAPD (Random Amplification Polymorphic Marker); ISSR (Inter Simple Sequence Repeat SSR (Simple AFLP (Amplified Fragment Length RFLP (Restriction Polymorphism SNP (Single Nucleotide Polymorphism) Real Time PCR.
