This thesis investigates the role of Copia-type retrotransposons, specifically Ty1 elements, in filamentous fungi like Aspergillus niger and Penicillium chrysogenum, focusing on their evolutionary and biotechnological significance. The study examines the structural characteristics, integration patterns, and functional impacts of AniTA2, a Copia retrotransposon identified in A. niger, with attention to its influence on genes linked to industrially relevant traits. Further, it discusses the application of Ty1 retrotransposons in industrial strain development, highlighting both their potential to enhance fungal strains and the challenges posed by genomic instability. The research concludes with future possibilities for using genome-editing tools like CRISPR/Cas9 to harness Ty1 elements safely for fungal biotechnology.27enRetrotransposonsAspergillus generaPenicillium generaGenomic diversityTransposable elementsAniTA2Ty1 elementsLTR retrotransposonsGenome plasticityCopia-type retrotransposons2024 Update of Retro-Transposons in the Aspergillus and Penicillium Genera and Other Filamentous FungiBiology::BiochemistryHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
