Abstract The process of programmed cell death is essential for plant ontogenesis. Seed development reveals the key role of programmed cell death in cell elimination and formation of new structures. Morphological data and biochemical regulators of programmed cell death during formation of the embryo sac and seed are discussed in the review.
