part of adhesion of symbiont infection structure to host adhesion of symbiont appressorium to host https://github.com/geneontology/go-ontology/issues/21505 GO:0075003 biological_process Note that this term should not be used to annotate gene products of the host. It should only be used to annotate those gene products from the symbiont involved in this process. The attachment of an appressorium of the symbiont to its host via adhesion molecules. The host is defined as the larger of the organisms involved in a symbiotic interaction. adhesion of symbiont appressorium to host during symbiotic interaction appressorium formation
