(C-E) Relative GFP-Staufen (E) coverage of motile (white) and non-motile (grey) oskMS2-GFP trajectories. Numbers within the boxes indicate the number of trajectories and the number of ooplasms (in brackets) analysed. Percentages above the plots show the fraction of RNPs that were found stably and reliably associating with the indicated protein (for at least half of the duration of the trajectory, p<0.01, binominal distribution, see also Fig EV2B). P values of pairwise Mann-Whitney U tests are indicated above the boxplots.
