Key findings
L. thermotolerans transcript share is ~24% anaerobic vs ~8% aerobic, with anaerobic depth sufficient to recover mixing-responsive genes.
Methodology
Kept S. cerevisiae and L. thermotolerans near equal abundance via dilution rate and profiled mixed transcriptomes under anaerobic vs aerobic conditions.
Limitations
Imposed equal biomass is experimental; results are model-fermentation dependent.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Time-of-day and mixed-culture design change the biological contrast RNA-seq is actually making. Tomato–DC3000 resistance was highest at 08:00 and susceptibility at 20:00, with red light the most disease-suppressive wavelength among those tested; in a chemostat co-culture, L. thermotolerans contributed about 24% of transcripts anaerobically versus about 8% aerobically.
Evidence for the claim as stated.
How far a transcriptome may be generalised is itself in dispute in these papers. Tomato red-light findings are not automatically all crops; mixed-yeast dilution rates are experimental; LCL methylation–expression links may not hold in primary tissues; coral DEGs do not settle field etiology.
