Additional file 3 of Gene expression dynamics of natural assemblages of heterotrophic flagellates during bacterivory

Additional file 3: Table S2. Statistical test supporting the selection of candidate genes related to bacterivory. The two first columns show the number of gene expression observations for the 12 heterotrophic and 5 phototrophic species in all possible samples (dots in Fig. 5). For genes with at least 15 observations in the two groups, we performed a randomization test with 10000 permutations to test whether each gene was more expressed in heterotrophs than in phototrophs. In addition, when there was a much larger number of observations in heterotrophs than in phototrophs, the gene was considered to be more expressed in heterotrophs. In this selection, we also included the patterns of overexpression reported in Fig. 3 displayed in the ‘FC > FC(HK)’ column (‘Yes’ represents overexpression in at least 3 out of 4 incubations). The data leading to the negative selection form this list are marked in red.
