Open pangenomes carry broader pathway diversity
Species with more open pangenomes have broader metabolic pathway repertoires after controlling for genome count and taxonomy.
Opportunity Hooks
candidate
Functional Innovation KO Atlas Reuse Test
Test whether the Functional Innovation KO Atlas helps explain pangenome, pathway, or plant-microbiome signals beyond generic annotation summaries.

candidate
Pangenome Openness Confounder Audit
Audit whether openness-function relationships remain after controlling for taxonomy, genome quality, sampling density, and annotation completeness.

Open pangenomes carry broader pathway diversity
Hypothesis
Open pangenomes have more diverse metabolic pathway repertoires because accessory gene flow expands niche breadth.
Testable With
Pangenome openness metrics, GapMind pathway summaries, genome-count controls, and taxonomic stratification.
Caveat
Sampling depth can create apparent openness and apparent pathway diversity simultaneously.
