Separate MetG2-associated gene responses from demonstrated root colonization and reciprocal benefit #1845

Finding

CommunityMech:000302, doi:10.1016/j.rhisph.2025.101142. Preserve rhizosphere motility/biofilm-associated expression, enrichment of plant-associated functional genes and host hormone/nutrient/stress transcriptional responses. Gene expression is not direct imaging of root movement or proof that one organism facilitates another. Remove unsupported mutualism and colonization-facilitation typing. Remove the context-only expression-to-functional-enrichment arrow; retain the proposed microbial-function-to-host-response direction as HYPOTHESIZED/PARTIAL, not measured transfer or established temporal mediation. Do not attribute all native-rhizosphere responses solely to the inoculant or one phylum. Remove redundant community-level source/target links and keep the unresolved canonical member/host identity boundary explicit.

Primary Source And Review Scope

https://www.sciencedirect.com/science/article/pii/S2452219825001272
Four whole records and their existing graph evidence were read. Source coverage is indexed publisher abstracts/previews, plus the independently retrieved Chlorella EuropePMC abstract. The MetG2 Introduction and bounded section previews were read, not the full article. Direct publisher requests returned HTTP403; the public Crossref-advertised API links for the two CC-licensed articles returned HTTP400. No access bypass, whole-paper/supplement/figure-pixel certification or raw-data reanalysis.

All four matching issue bodies were read. Fresh all-state title/body dedup and scoped ignored/hidden local searches found no duplicate of this finding; PRs/comments were not exhaustively searched. Existing #1091/#1093 concern cache infrastructure, #184 scouting dedup, and #183 has a separate membership/access scope.
