Confocal microscopy images of F-actin in germinated pollen in the wildtype and antisense line.

<p>Pollen and pollen tubes were stained with rhodamine phalloidin. A normal F-actin strand distribution was seen in wildtype pollen tubes (<b>A, B</b> and <b>C</b>). F-actin appears disorganized and pollen tube growth arrested in antisense pollen (<b>D, E</b> and <b>F</b>). Scale bars are: 10 µm in <b>A, B, C, D, F,</b> and 5 µm in <b>E</b>.
