Two days after emasculation, stage 12 zix/ZIX flowers were manually pollinated with self or wild-type pollen and the pistils were dissected 1.5 d later. Whole-mount ovules and seeds were cleared with chloral hydrate and scored under a DIC microscope. s, selfed; c, crossed with the wild type; :n, numbers of ovules from five to six siliques; zy, early symmetric zygote; end, endosperm nuclei; ez, elongated zygote; 1c, one-cell embryo; 2c, two-cell embryo; unf, unfertilized ovules; pn, unfused polar nuclei.
