摘要

Intracellular distribution of assimilated 2,4,6-trinitrotoluene (TNT) in callus cells, flower buds, and leaves of intact Yucca gloriosa L. plants with the use of electron microscopy radioautography was carried out. The radiotracer was detected in vacuoles, plastids, mitochondria, endoplasmic reticulum, and cytoplasm. It was found that TNT incorporation in the vacuoles of dedifferentiated callus cells was higher compared to cells from intact plant. Therefore, the ultrastructural continuity of differentiated cells is less damaged.
