*Justus CD, *Anderhag P, *Goins JL, Lazzaro MD (2004) Microtubules and microfilaments coordinate to direct a fountain streaming pattern in elongating conifer pollen tube tips. Planta 219:103-109.

Figure 2: Organelles move in a fountain pattern as the pollen tube elongates. All videos captured at 1 fps and replayed at 10 fps. (3 MB)
Figure 3: After microfilaments are disrupted by latrunculin B, organelle streaming and pollen tube growth stops. Thin tubules steadily accumulate throughout the tip. (2 MB)
Figure 5: After microtubules are disrupted by APM, organelle streaming is reduced and pollen tube growth stops. The organization of the tip collapses but the plasma membrane remains intact. (3 MB)
Figure 7: Before propyzamide, organelles stream in a fountain pattern. After microtubules are disrupted by propyzamide, organelles streaming switches to a reverse fountain pattern that becomes more distinct over time. (6 MB)
Figure 9: After microtubules are disrupted by oryzalin, organelle streaming also switches to a reverse fountain pattern as vacuoles move into the tip. The reversal begins at the start of this sequence and becomes more distinct over time. (6 MB)
