Model Showing the Role of the Splice Variants ARF8.4 and ARF8.2 in Stamen Elongation and Anther Dehiscence during Late Arabidopsis Development.

Anther developmental events, stamen filament elongation phases, and relevant gene functions (MYB26, DAD1, and AUX/IAA19) from stages 9 to 13 (Bowman, 1994). ARF8.4 and ARF8.2 expression, as inferred from our in situ hybridization data, was simplified, only showing transcript localization in the endothecium and in the anther or stamen filament procambium. En, endothecium; P, procambium.
