Reciprocal crosses show that female fertility was affected.

<p>(A) Seed development in representative siliques of reciprocal crosses using pollen from <i>atvdac1</i> plants to pollinate wild-type (WT) pistils and using pollen from WT plants to pollinate <i>atvdac1</i> pistils. The arrows indicate undeveloped ovules. Bars = 1 mm. (B) Seed development in the representative <i>atvdac1</i>/+ selfed silique and in representative siliques from reciprocal crosses between WT and atvdac1/+. Bars = 1 mm.
