The paper selects the horizontal transfer of toxic plasmids that are essential for ausnobacteria disease.
Time of Update: 2020-07-27
sometimes, plasmids can be transferred horizontally between strains and strains of bacteria, making it difficult to understand the evolution and diversity of pathogens.
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.

It took more than two years for the scientists to observe how bacteria "eat" stones.
Time of Update: 2020-07-27
rocks form soil through weathering reactions, but this process is difficult to observe for humans.
and organisms that use stone as an electronic source are called chemoautotrophs, which can eat rocks for a living.
therefore, bacteria can indeed initiate and accelerate the process of rock weathering into soil.
