Abstract: | We studied the process of apoptosis in etiolated wheat (Triticum aestivum L.) seedlings. As a result, an integral pattern of the apoptotic plant cell ultrastructure was established. In the apoptotic cells of the coleoptile, we observed chromatin condensation and margination, an increased density and specific cytoplasm fragmentation accompanied by the appearance of unusual cytoplasmic vesicles containing subcellular organelles, mitochondria in particular, in the vacuoles. |
