Overexpression of AFH3-NΔFH1FH2 Induces the Formation of Excessive Actin Cables in Tobacco Pollen Tubes and Causes Swollen Pollen Tubes to Swell.
(A) and (B) A control pollen tube transformed with Lat52:GFP-fABD2 (1 μg), showing the actin cytoskeleton at the medial section of the pollen tube (A) and a projection of the whole pollen tube (B).
(C) and (D) A typical pollen tube cotransformed with Lat52:GFP-fABD2 (1 μg) and Lat52:NΔFH1FH2 (3 μg). A medial section of the pollen tube (C) and a projection of the whole pollen tube (D).
Bar = 5 μm.
