In 141 Escherichia coli adaptive laboratory evolution experiments, Fisher exact testing at 5% FDR found 74 significant gene pairs (36 co-occurrences, 38 mutual exclusivities).
- Why it matters: Testing all mutation combinations is impractical, yet epistatic interactions shape adaptive phenotypes and combinatorial strain engineering; robust candidate detection is needed from ALE data.
- What they did: The authors screened gene-pair co-occurrence and mutual exclusivity using Fisher exact test and DISCOVER on ALEdb, applying multiple-testing correction separately by experiment, method, and direction.
- The result: DISCOVER found 5 significant mutual-exclusivity pairs, all also significant by Fisher; Fisher-only pairs often reflected multiple strain labels or single-mutation recording, and power benchmarks were 70 independent endpoints (co-occurrence) and 215 (mutual exclusivity) for 80% power.
