Radiation biology of cultivated plant cells

The potentials of these and other ap¬proaches have been presented elsewhere in this volume. This discussion is focused on the radiation2 biology of cultured plant cells. Where information is incomplete or absent for cultured plant cells, we have drawn upon the microbial and animal cell literature for reference. In animals the lethal effects of ionizing radiation are reflected in killing of specific cell types (e.g. crypt cells of the intestine and the stem cells of the bone marrow), and this determines the survival frequency of the irradiated animal population (HALL, 1973). King P J (1984) and Venkateshwarlu M (2020).Nevertheless, studies on cultured mammalian cells have contributed much to our present understanding of the biochemical, biophysical, and genetic aspects of radiation damage and recovery in animals (see ELKIND and WHITMORE, 1967; CLEAVER, 1974). Rajendra Prasad et al (2018), Venkateshwarlu M (2019). In contrast, irradiation of plants, while produc¬ing some differential cell killing, does not appear to induce death of the organism by affecting a single cell type. Thus, studies with plant cells in culture may reflect more the effects of penetrating radiation on the organism as a whole than those with animal cell cultures. Venkateshwarlu M (2019 & 2008)
