[Ultramorphometric study of the plastids in apical tuber cells of original and transgenic potato plants treated with ambiol].
Ultramorphometric characteristics of plastids in cells of apical tuber meristems of original and defensin gene-transfected potato (Solanum tuberosum L.) plants, either maintained under normal conditions or subjected to treatment with the antioxidant ambiol, were compared. Under normal conditions, the tuber cells of the original and transgenic potato plants differed in neither the number nor size of the plastids. Only certain quantitative distinctions in the development of individual ultrastructural characteristics of plastids were detected. Treatment with ambiol enhanced the differentiation of the internal membrane system of plastids in the cells of original and transgenic plants, especially the tubular membrane systems. Certain differences in the responses to ambiol of cell plastids of original and transgenic plants were related to plastid sizes and development of individual intraplastid structures. The results comply with earlier data on varying responses of mitochondria of original and transgenic plants to ambiol treatment.
