(C) Kymograph of oskMS2-GFP mRNPs (cyan) travelling along polarity marked MTs (red, EB1 protein) in an ex vivo ooplasmic preparation. White dashed arrow shows the growing plus tip of the MT. Scale bars represent 1 s and 1 µm, respectively.(D) Distribution of oskMS2-GFP mRNP runs towards plus (white) and minus ends (grey). Numbers within the bars indicate number of runs. P value of Chi2 test against wild-type is indicated above each bar.
