Abstract

It is proved hat volatile substances excreted into urine of intact mice stimulate immune reactivity of spleen and regional lymph nodes in mice exposed to radiation at dose of 1 Gy. Seeds of agricultural plants both intact and exposed to radiation are found to be able to reciprocally modify initial growth parameters through aerial environment and sprouting medium. Modification of radiation-induced effects, common for both animals and plants, is thought to be carried out by the use of volatile chemosignals released by the species.

Key words
Bystander effect, ionizing radiation, mice, seeds of agricultural plants, volatile substances.
