Studies on the developmental mechanism of mutated cells induced in irradiated rice seeds

Considering the present results, a hypothetical scheme was set up as shown in Fig. 6 which may explain the developmental mechanism of the induced mutation in the R1-plant. In the scheme, the circles in which tiller numbers are marked mean the corpus cell groups leading to the fcrmation of the generative tissues of the numbered tillers, in the shoot apex of the irradiated embryo.
