*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.

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.

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)
