Abstract. Understanding how transposable elements (TEs) transition from rapid amplification to functional decay is fundamental to unraveling the mechanisms

Half of our genome is made of transposons — snips of DNA that can move and copy themselves. But they’re more than parasites or genetic junk.

The family Tetraodontidae comprises 193 valid species of teleost fish distributed in tropical and subtropical regions worldwide. Available cytogenetic information for 31 species indicates extensive va...

Diutina catenulata is an ascomycetous yeast of environmental and emerging clinical relevance. Genome analysis of strains representing the major phylogenetic lineages of the species revealed a strong genetic structure, with deeply diverged clades displaying limited gene flow, likely reflecting clonal propagation or long-term historical divergence. A notable feature of D. catenulata genomes is an extensive degree of chromosomal instability associated with two DNA transposons, Dici1 and Dici2, present across all lineages, with up to 96 Dici1 copies in the type strain CBS 565T. We experimentally demonstrate that both elements remain active and mobilize under laboratory conditions. High sequence conservation among Dici copies supports a recent and ongoing transpositional burst reshaping genome architecture. Related elements identified in multiple fungal species define a previously undescribed family of DNA transposons related to the IS630-Tc1-mariner superfamily. These findings provide a fr
