Table I. Distribution of immunogold particles with GFP antibodies in transgenic PIN1:GFP-F165A Arabidopsis root cells.

Significant differences between the two compartments/organelles (multilayered structures and Golgi) were analyzed using a two-tailed paired Student’s t test (**, P < 0.001).

Compartment/Organelle	No. of Organelles	No. of Immunogold Particles	Immunogold Particles per Organelle
Multilayered structures	30	80	2.66**
Golgi	30	5	0.16**
Multivesicular bodies	30	6	0.20
Mitochondrion	30	5	0.16
