The paper selects the horizontal transfer of toxic plasmids that are essential for ausnobacteria disease.

Click on the blue words above to focus on our comprehensive evolution of Agrobacterium pathogens and their virulence plasmids. The analysis reveals new epidemiological patterns and highlights the importance of horizontal gene transfer in the diversification and persistence of plant diseases.these findings may help to provide information for the development of policies aimed at preventing the emergence of refractory diseases in agricultural environments and their global spread. Br / > they are different from the natural DNA molecules in the cell, and they can confer a virulence on the DNA.therefore, they are a powerful driving force for the evolution of pathogenic bacteria.sometimes, plasmids can be transferred horizontally between strains and strains of bacteria, making it difficult to understand the evolution and diversity of pathogens.however, this information is essential for assessing the epidemiology of the disease.Agrobacterium is a group of soil bacteria that can use horizontal gene transfer to inject Tumor Inducing plasmids into plants, leading to incurable diseases in important crops.understanding the molecular basis of how agricultural pathogens emerge and diversify is essential to ensure global agricultural security.Alexandra Weisberg and colleagues have developed a novel multi method strategy for characterizing virulent plasmids and used it to analyze an 80 year old Agrobacterium strain collected from all over the world.this method enables Weisberg et al. To separate the strains and plasmids into independent defined evolutionary lineages.the authors found that despite the high level of recombinant plasmids, the diversity of plasmids was unexpectedly low, indicating that they originated from some conservative Agrobacterium plasmid lineages.although the limited plasmid lineage is puzzling, it is clear that plant breeding systems have affected the transmission of plasmids into various genomic trunks.welcome to Science official account, click below to read the original text.
