Bound lettuce consortium graph to compatibility screen, gene copies and plant outcomes #1558

kb/communities/Lunar_Martian_Simulant_PGPB_Lettuce_SynCom.yaml, DOI:10.1007/s00374-025-01923-3. No inhibition zone is a screening result, not demonstrated commensalism or a causal route to rhizosphere establishment. Rhizosphere nifH/phoD/BPP DNA copies increased in non-amended treatments, but are not expression, nutrient flux or strain-resolved colonization; the paper explicitly says metabarcoding cannot track inoculated strains. Remove both screening/mediation arrows and unsupported interaction/mechanism labels while retaining all three measured observations. Preserve treatment-level biomass and nutrient-content benefits without mutualism, IAA mediation, uniform nutrient-concentration effects, or Martian-environment claims. Correct living-host evidence and explicitly list the four canonical inoculants, not the entire rhizosphere. Close only after protected-main merge.
