parasitic

Label: Plant parasitism status
Entity URI: https://w3id.org/APD/traits/trait_0030029
Type: categorical
Definition: A whole plant [PO:0000003] phenotype [NCIT:C16977] trait that indicates if a plant is involved in a parasitic [ECOCORE:00000146] symbiosis [ECOCORE:00000022] where it forms haustorium [GO:0085035] on a host [GO:0018995] plant and the host plant provides all or some of its high energy [PATO:0001021] carbon [CHEBI:27594] compounds [NCIT:C43366], mineral nutrition (nutrients [CHEBI:33284]) and/or water [CHEBI:15377].;Trait indicating whether a plant forms haustoria and obtains part or all of its energy-rich carbon compounds (photosynthetic sugars), mineral nutrition and/or water directly from another plant (its host) in an interaction that does not benefit the host plant.
Additional comments: Plants described as parasitic in the context of this trait always have haustoria, specialised organs that penetrate the host plants's vascular bundles. The trait `root_structures` documents symbiotic relationships with fungi. The trait `plant_energy_acquisition_strategy` documents specialised strategies or specialised organs or tissues plants use to obtain carbon or mineral nutrition.

Allowed values:

value	description
hemiparasitic	Plant that is photosynthetic but augments its energy, mineral nutrition, and /or water supply through parasitism. This trait value does not distinguish between obligate hemiparasites, plants which require a host for at least part of their life cycle, and facultative hemiparasites, plants which can grow and reproduce without a host.
hemiparasitic_facultative	Plant that is photosynthetic and can grow and reproduce without a host but augments its energy, mineral nutrition, and /or water supply through parasitism.
hemiparasitic_obligate	Plant that is photosynthetic but requires a host for at least part of its life cycle.
holoparasitic	Plant that obtains all (or nearly all) of its energy through parasitism.
not_parasitic	In the context of this trait, a plant that does not acquire energy, mineral nutrition, and/or water via haustoria connected to another plant. It can include species that form a symbiosis, including a parasitic interaction, with a fungal partner.
parasitic	Plant that obtains some energy, mineral nutrition and/or water through parasitism. This term is used if a dataset does not specify if a plant is a hemiparasite or a holoparasite.
root_parasitic	Parasitic plant whose haustoria penetrate the root of a host plant.
stem_parasitic	Parasitic plant whose haustoria penetrate the stem of a host plant.
