pathogen effector mediated modulation of host immune system process presence of pathogen necrotrophic effector-mediated host programmed cell death 2019-01-14T12:22:36Z gain of host necrotic cell death presence of host lesion This term is to be used when the pathogen actively induces the host responses, not for host protection against the pathogen. An effector is an entity derived from a pathogenic or non-pathogenic species that either activates or suppresses host defenses or other host responses. pathogen_host_interaction_phenotype presence of effector-mediated host programmed cell death during necrotrophy gain of effector-mediated host programmed cell death during necrotrophy presence of host necrotic cell death A phenotype where the process of a necrotrophic pathogen effector activating the host immune system to trigger programmed cell death is present. alaynecuzick PHIPO:0000476 gain of presence of host lesion presence of pathogen-associated host lesions
