symbiont-mediated induction of tumor or growth in host
The process in which a symbiont causes the formation of a mass of cells in a host organism. While these growths are often called nodules, they are not formed as nitrogen-fixing structures, but rather to provide an environment for the symbiont to grow. In this sense they are parasitic structures rather than mutualistic.
