Effects of cytoskeletal inhibitors on the widths of MT and RanGAP bands in late prophase cells of 4-day-old onion root tips

	Late prophase cells with a MT band and a RanGAP band
	Width of MT band	Width of RanGAP band
Treatment	(µm)	(µm)
0.2% DMSO	3.51 ± 0.11a,b,x (n = 13)	3.27 ± 0.29c,d,x (n = 13)
20 µM oryzalin	2.30 ± 0.35a*, y (n = 9)	3.20 ± 0.49c,y (n = 9)
10 µM LatB	5.05 ± 0.29b*, z (n = 19)	3.72 ± 0.41d,z* (n = 19)

PPBs in root tips were synchronously induced 7 h after their transfer from 5- AU to distilled water. Seedlings were treated with drugs for 15 min before fixation. The width of MT band and that of RanGAP band in late prophase cells having both MT and RanGAP bands were compared. All values show the mean ± standard error from late prophase cells. Letter n in parenthesis indicates the number of examined late prophase cells. Student t-test was carried out between samples indicated with the same small letter (a~c and x~z).

^*indicates significant difference from the corresponding control value (P < 0.05).
