Colza cell autophagy induced of high dose of industrial sewage sludge

Résumé

This preliminary study is to evaluate the effects on colza of land application of industrial sludge containing heavy metals especially lead and chromium. We are interested in high doses spreading 100t/ha to better observe the phenomena of induced transformations on colza by the absorption of heavy metals. We used the technique for ultrastructural observation in a transmission electron microscope. The colza cells show a compaction and marginalization of nuclear chromatin, nuclear membrane and cytoplasmic convolution and condensation of cytoplasm. The kernel then fragments, each fragment are surrounded by a jacket. Some cytoplasmic and nuclear elements are released and are phagocytized by neighboring cells. We observed vacuolation of the cytoplasm and the formation of autophagic vesicles.
