The role of the quiescent centre in the recovery of Vicia faba roots from radiation

· Radiation Botany
The suggestion that cells in the quiescent center of bean root meristems are relatively insensitive to radiation and promote recovery in irradiated roots is discussed. Experiments indicate that the cells from which root recovery takes place are not protected by anoxia in normal roots; also that the progenies of these cells have the same radiosensitivity as normal meristems. Calculations are presented which show that the number of cells in the meristem surviving irradiation is enough to promote recovery without attributing any special degree of protection to any of the cells; but if recovery can only take place from a small region of the root, the possibility cannot be excluded that cells in this region have reduced radiosensitivity.
