Lazzaro MD, *Marom EY, Reddy ASN (2013) Polarized cell growth, organelle motility, and cytoskeletal organization in conifer pollen tube tips are regulated by KCBP, the calmodulin-binding kinesin. Planta 238:587-597.
Figure 1:
Calmodulin inhibition by W-12 perfusion reversibly slows
pollen tube elongation and alters the organization of
organelles within the elongating tip. (42 MB)
Figure 4A-B:
Constitutive activation of KCBP by antibody microinjection
to displace calmodulin causes the migration of vacuoles
into the tip and the subsequent cessation of organelle
motility with a visible tensioning in the cytoplasm. (9
MB)
Figure 4C-D:
Control microinjection of preimmune serum does not effect
organelle postioning as streaming continues. (23 MB)
