Fig. 4. Golgi-bodies in wild-type Arabidopsis and crooked cells. (A) Single wild-type and crooked `a' trichomes of the same age, showing the differences in distribution and density of Golgi bodies. (B) Regional variation in distribution of Golgi bodies in a crooked trichome. The tip region has not expanded well but is densely packed with Golgi bodies (arrowheads). (C) Magnified view of a region exhibiting accumulation of Golgi bodies (arrowhead). (D) Co-visualization of F-actin bundles using YFP-mTalin fusion protein (green) and Golgi-bodies using ERD2-GFP label (red) in a crooked trichome shows that multiple Golgi bodies (such as those seen in C) are trapped in regions of dense actin (white arrowheads), whereas more loosely distributed, free Golgi bodies occur in expanded areas (green arrowheads).
