Statistical significance was determined by an adjusted p-value ≤0.05. The standard deviation (±) was calculated based on the entire population.
ΔH, M. thermautotrophicus ΔH.
ZZ, M. thermautotrophicus Z-245.
MM, M. marburgensis Marburg.
Coefficient of variance (CV) values for the transcriptomics data were calculated using transcripts per million (TPM) values and can be found in Sheets 1–3 of Data S4 and Figure S6B.
Coefficient of variance (CV) values for the proteomics data were calculated using iBAQ values and can be found in Sheets 7–9 of Data S4 and Figure S6B.
DE, differential expression.
DA, differential abundance.
