(Phys.org)—A team of researchers with members from Belgium, China, Peru and the U.S. has found evidence of bacterial DNA in the genome of the cultivated sweet potato. In their paper published in Proceedings of the National ...
It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of ...
