Table 3.

Number of differentially expressed transcripts in comparisons of the experiment groups of the 19th DLR parabolic flight campaign. Differential expression is defined as t-test p-value < 0.05; fold change (FC) ≤ −1.3 or ≥ +1.3. If the ratio is <1, FC is calculated as the negative reciprocal of the ratio. The term “transcripts” refers to 188 oxidative stress-related transcripts, representing 86 genes. For the abbreviations of the experiment group names see Table 1.
