Abstract

The morphological features and fine structure of wheat egg cell protoplasts isolated from premature (3 days prior to anthesis) and overaged (12 days after anthesis) caryopses were compared. Except for shape, the young egg cell protoplast showed the same morphological characteristics as the egg cell in planta at the time of anthesis. Young and adult egg cell protoplasts were spherical in shape. Polarity could not be identified exactly with the methods used. During aging, the egg cell increased considerably in volume. The adult egg showed the typical features (membrane blebbing, autophagous vacuoles) of programmed cell death. It appears that after a long life-span (about 18 days) cells of the female gametophyte undergo apoptosis.
