A research team at the University of California, Santa Barbara, examined the role Rhs play in intercellular competition in bacteria. They found that Rhs proteins enable Dickeya dadantii 3937, a phytopathogenic bacterium that causes soft rot diseases on many crops, to compete with members of its own kind through touch-dependent killing.
