Throughout the evolution of life on earth, bits of genetic material are routinely swapped among different species of bacteria to give them a competitive advantage. But rarely do such gene transfers happen between bacteria and higher organisms.
Now, Prof. Nikolas Nikolaidis, et. al., report on a rare case where plant genes called expansins, which are responsible for loosening or weakening protective cell wall, were transferred from plants to bacteria, fungi and amoeba that are known plant pathogens or live nearby in the soil.
