Sodium sulphite and sodium benzoate induce in Vicia faba root meristems: (1) dose-dependent reduction in mitotic figures, (2) intact and severed anaphase bridges, (3) premature chromosome condensation heading to pycnotic nuclei, and (4) chromatin erosion in interphase nuclei. The effects are due to the anions and not due to the sodium ions. Complete recovery of mitotic figures and normal chromosome configurations were observed within the first 23-46 h of regrowth. Recovery was accompanied by… CONTINUE READING
