When nitroso methylurea‐treated seeds of Arabidopsis thaliana were again subjected to a pulse treatment of inhibitors of DNA or protein synthesis or respiration, after 40 hours of recovery, an increased number of chlorophyll‐deficient sectors was realised. Such an increase cannot, however, be obtained if the seeds are irradiated with X‐rays followed by treatment with inhibitors. The probable reasons for this differential response to NMU and X‐rays are discussed. It is proposed that the increase in sector frequency is obtained through a process, similar to somatic recombination.
