Mature pollen from open flowers was collected and normal and shriveled grains counted by light microscopy. Maturing siliques were dissected and viewed under a dissecting microscope to look for significant numbers of failed ovules (≥≥5 failed ovules/silique). All data represent at least two independent plants of the indicated genotype.
