Inactivation of <i>AtWAPL</i> rescues <i>Atctf7</i> mutants.

<p>(A) Thirty day-old wild-type (left), <i>Atctf7</i> homozygous (middle) and <i>Atwapl1-1wapl2ctf7</i> triple homozygous (right) plants. (B) Alexander staining of anthers showing pollen viability in <i>AtCtf7^+/−</i>, <i>Atctf7</i>, <i>Atwapl1-1wapl2</i>, <i>Atwapl1-1wapl2Ctf7^+/−</i> and <i>Atwapl1-1wapl2ctf7</i> plants. Viable pollen stain red, while nonviable pollen stain green. Size Bar = 10 µm (C) Seed set in <i>Atwapl1-1wapl2Ctf7^+/−</i> and <i>Atwapl1-1wapl2ctf7</i> plants is lower than that observed in <i>Atwapl1-1wapl2</i> plants. Images shown represent the most common phenotypes observed.
