Figure 5. — The G92 Globular Structures Are Enwrapped in Actin Cables, and Their Maintenance Is Independent of the Integrity of the Actin Cytoskeleton.

Confocal images of cotyledon epidermal cells of T1 G92 transformants expressing the actin marker YFP-ABD2 (G92/35S:YFP-ABD2). Bars = 5 μm.

(A) Images taken at the cortex of the cell show distended actin cables (arrow) and Golgi bodies labeled with ST-GFP (G92 panel, arrowhead) that appear often in association with actin (see merge panel).

(B) In cross sections of untreated cotyledon cells (-LatB), actin cables appear to form a basket around the G92 structure (arrow) and are also visible inside the structure (arrowhead). The G92 structures withstood treatment with latrunculin B (+LatB) despite the actin cables having lost their organization.
