Análisis de los principales elementos genéticos móviles en diferentes subespecies de Xylella fastidiosa

Xylella fastidiosa is a phytopathogenic bacterium that significantly impacts economically important crops such as grapes, citrus, and coffee. Originally confined to the Americas, recent outbreaks of this bacterium have emerged in various countries across Europe and Asia, posing an increasing threat to global agriculture due to its easy spread through vectors that feed on the sap of infected plants. This study focuses on examining the impact of mobile genetic elements (specifically IS, ICE, CIME, and IME) on the pathogenicity of Xylella fastidiosa. These elements are known for their ability to transport and reorganize genes within the bacterial genome, which can result in significant changes in the bacteria's pathogenic capabilities. Our results indicate that, despite the low abundance and distribution of IS, ICE, and IME, these elements contain virulence-associated genes and indeed influence the pathogenicity of the bacterium. Additionally, the presence of prophage genetic material in IS and IME suggests their relevance in the genomic configuration of the pathogen. In conclusion, our findings provide new insights into how mobile genetic elements contribute to the virulence of Xylella fastidiosa.
