The Cortical Microtubules Depolymerized More Rapidly in csi1-2 Cells under Dehydration Treatment.
The cortical microtubules of light-grown hypocotyl cells of 4-d-old GFP-TUA6 (A), csi1-2×GFP-TUA6 (B), GFP-MAP4 (C), and csi1-2×GFP-MAP4 (D) seedlings upon treatment with PEG6000 (20%, w/v, in liquid MS media) for 0, 4, 8, 12, 24, and 36 h, respectively. csi1-2 showed increased depolymerization of cortical microtubules.
