formation of specialized structure for nutrient acquisition formation of arbuscule for nutrient acquisition https://github.com/geneontology/go-ontology/issues/20305 biological_process GO:0075328 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. formation by symbiont of arbuscule for nutrient acquisition from host The assembly of an arbuscule, a fine, tree-like hyphal symbiont structure projected into the host cell for the purpose of obtaining nutrients. The host is defined as the larger of the organisms involved in a symbiotic interaction.
