Transposons and their application in plant pathology

Prokaryote, viruses, and eukaryotes chromosomes contain fragments of DNA can move and migrate to other parts of the chromosome calling as Transposition and play an important role in new combinations of gene production. DNA fragments carrier the genes or transposons are the transposable elements that may called gene mutant also. Transposons can move to another position of the same chromosome or other chromosomes. Genomic transposable elements are used in Mycology and Plant Pathology in various aspects, including the Cloning of genes effective in pathogenesis (Transposon tagging), or to identify specific races of virulent bacteria, viruses, and fungi in infected plant tissue, study of the evolutionary relationships of fungi, study of population structure and dynamics and epidemiology of fungal pathogenic isolates, diagnosis of divergent populations and the introduction of transposon-based markers.
