| 内容記述 | Among plant species, coniferous plants are particularly sensitive to ionizing radiation. We examined the effects of X-ray irradiation on cultured cells of Japanese cedar. Cell death in the cultured cells was increased drastically by X-ray irradiation at 5 Gy, which is as low as the dose inducing radiosensitive programmed cell death, i.e. apoptosis, in mammalian cells. The advancement of cell death in the Japanese cedar cells was accompanied by nuclear DNA fragmentation, which is typically observed both in apoptosis of mammalian cells and in hypersensitive programmed cell death observed in plant cells exposed to various environmental stresses. The results suggested that radiosensitive cell death should be involved in the susceptibility of coniferous plants to ionizing irradiation, and furthermore, this death should be a kind of programmed cell death which has a similarity to apoptosis in mammalian cells. | |||||
