fungal nematophagy

Resolve the broader feeding hierarchy without imposing a capture mechanism or carbon-specific endpoint.

Feeding on living or previously dead nematodes is included; fungal killing, obligacy and starvation are not universal requirements. Mere contact, paralysis, killing, trap formation or a sequence annotation alone is insufficient. Fungal nematode-trap formation (traitmech:000718) is structural, neither necessary nor sufficient for feeding. Mycoparasitism (traitmech:000717) has fungal prey; predatory bacterium (traitmech:000054) has a bacterial actor and prey. Phagotrophy (traitmech:000628), myzocytosis (traitmech:000631) and pallium feeding (traitmech:000632) impose different uptake modes. Saprotrophy (traitmech:000055) can overlap, without organism-level disjointness. Local parasitism (traitmech:000043) inherits persistent association, not required here. Keep phenotype METPO:1000059 pending a closer feeding hierarchy; no universal carbon, nitrogen or energy contribution is specified. Bare nematophagy includes nonfungal actors and is not an exact synonym. No unverified synonyms or xrefs are asserted.

Pinned and current METPO lack an exact active counterpart in the inspected scope. Historical METPO:0000005 and METPO:000005 are deprecated and replace to active METPO:1000631 trophic type, a carbon/energy axis rather than this prey-defined feeding phenotype. METPO:1000644 is organic-carbon heterotrophy and METPO:1000731 concerns nutrient-availability adaptation. Deprecated METPO:0000261, METPO:000262 and METPO:1000125 concern fungal spores; METPO:1000227 is parasitism. No replacement or consider annotation was observed for those four. Their OMO:0001000 reasons neither invalidate biology nor authorize reuse. Historical IDs are not exact xrefs. The pinned ontology remains unchanged; v595 proposes the new class.

Resolve source inconsistencies and taxon-paired effectors before adding a causal graph.

Marlin's Table 2 conflicts with its Introduction on two host responses; Table 3 and Results differ for P. artyukhovskii. Those disputed host ranges are not imported. den Belder's Figure 2 panel labels/caption, Table 3 direction and significance notation disagree with prose; no numerical rates are adopted. Lin's Results uses mep1 where Table 1 and Figure 5 use mcp1; no protein identity is silently reconciled. Its linked DOI:10.1371/journal.pbio.3003178 is a later Update Article, not a correction or independent laboratory replication. Capture and digestion have distinct assays; expression associations do not establish universal effectors. No causal graph, protein example or chemical mechanism is asserted. Source-status checks are bounded: MDPI's notice page returned 403, and no comprehensive notice clearance is claimed. Source hashes, inspected sections and actual native verdicts are retained in the verification sidecar.
