Image series of horsetail mobility under X irradiation.
Without IR exposure (0 Gy; recording time 4 min) horsetail nuclei perform long continuous movements. Tracking of the leading edge of the nucleus (SPB) leads to continuous trails (each minute displayed in a different color) over the time recorded. Exposure to 100 Gy (a) X IR induced temporal slowing down of the mobility, resulting in alternating short and long tracks. In a subset of 100 Gy-irradiated nuclei (b) mobility is restricted to a small area and the nuclei display a condensed morphology. 200 Gy X IR (c) also induced alternating short and long tracks of horsetail mobility, while a subset of nuclei (d) displayed compete paralysis of mobility. Z overlays to the right show the tracks imposed on the cellular image, while “tracks” show the four differently colored 1 min tracks travelled by the leading edge only.
