Fig. 3: Bacterial abundances in the diatom–fungus co-cultures.
From: Fungal parasitism on diatoms alters formation and bio–physical properties of sinking aggregates
Abundances of diatom-associated bacteria are shown per individual Synedra cell (a) and per culture volume (b) on day 9. Bacteria were grouped based on their association with individual Synedra cells of different infection stages. The letters a–d in (a) denote significantly different groups (Kruskal–Wallis, P < 0.05, N = numbers of analyzed Synedra cells). Data are shown as single data points (white-filled circles), the 25th, 50th, and 75th percentile (grey boxes), mean values (blue and red-filled circles), and distribution curves (kernel smoothing). Data from the previous sampling days 0–6 are listed in Supplementary Data 2. Stacked bars in b represent individual sample replicates. c Abundances of free-living bacteria. Single data points are plotted as circles and lines connect mean values over time (symbols of mean values are not displayed). Time series data of free-living bacterial abundances were significantly different between both treatments (P = 0.012, GLMM, F4,16 = 4.591). Blue and red items represent data from the non-infected and fungal-infected cultures, respectively. Statistically significant differences at single time points are indicated with asterisks (***P < 0.001). b, c N = 3 incubation flasks.
