Abstract
Intracellular distribution of assimilated 2,4,6-trinitrotoluene (TNT) in callus cells, flower buds and leaves of intact Yucca gloriosa L. plants using electron microscope radioautography. The radiotracer was detected in vacuoles, plastids, mitochondrion, endoplasmic reticulum and cytoplasm. It was found that in dedifferentiated callus cells TNT was incorporated in the vacuoles in greater quantities in comparison with the cells of intact plant. Correspondingly the ultrastructural integrity of the dedifferentiated cells is less damaged.
