programmed cell death symbiont-induced defense-related programmed cell death biological_process Note that this term is to be used to annotate gene products in the host, not the symbiont. To annotate gene products in the symbiont that induce programmed cell death in the host, consider the biological process term 'symbiont-mediated activation of host programmed cell death' ; GO:0052042'. Cell death resulting from activation of endogenous cellular processes after interaction with a symbiont (defined as the smaller of two, or more, organisms engaged in symbiosis, a close interaction encompassing mutualism through parasitism). This can be triggered by direct interaction with the organism, for example, contact with penetrating hyphae of a fungus; or an indirect interaction such as symbiont-secreted molecules.
