Genetic diversity studies are crucial for understanding the genetic structure and evolutionary dynamics of fungal species and communities. Fungal genomes are often reshaped by their repetitive components such as transposable elements. These elements are key players in genomic rearrangements and are ideal targets for genetic diversity and evolutionary studies. Herein, we used three Ty3/Gypsy long terminal repeat retrotransposons, Grasshopper, Maggy, and Pyret, for genetic differentiation and diversity in soil and plant pathogenic fungi, representing diverse species, order, and phyla. Pyret DNA markers showed the highest gene diversity and Shannon's information indices, followed by Maggy and Grasshopper. The observed high levels of multilocus polymorphism indicate the continuous mobility of these elements after their transfer in the new host. In conclusion, this study presents novel markers for genetic differentiation and evolutionary studies of fungi, and sheds light on the prevalence of gene acquisition phenomenon in field fungi.
