Transposable elements in plant genomes

Transposable elements (TEs) are dynamic DNA sequences within plant genomes capable of moving from one location to another. Known for their “jumping” behavior, TEs contribute significantly to the complexity and adaptability of plant genomes. When they relocate, TEs can create mutations or introduce new genetic material, potentially altering gene function and enabling plants to adapt to stress. While many TEs remain inactive, some are regulated by epigenetic factors that control their activity to prevent genome instability. TEs have shaped plant evolution by driving genetic diversity across species. Researchers are exploring how TEs can be leveraged in plant breeding to enhance beneficial traits, offering possibilities for improved crop resilience and yield under environmental stresses.
