영문 초록

Responses of rice seeds and cultured cells subjected to high magnetic field stress ranging from 0.5 kilogauss(k gauss) to 4.0 k gauss were determined. The growth of roots exposed to magnetic field at 4.0 k gauss was stimulated by 8.8 and 14% over that of the control, whereas shoots inhibited by 7.0 and 10% in dry and imbibe treatment, respectively. Treatments of magnetic fields at 1.0 and 4.0 k gauss significantly increased the regeneration ability of roots from the cultured cells up to 60.7 and 63.7%, respectively, as compared with untreated control showing 50.1% at 30 days after treatment. Some increased and newly synthesized polypeptides, particularly the size of 22.3 kilodalton and pI 7.0, in the cells exposed to magnetic field of 4.0 k gauss were identified using two dimentional polyacrylamide electrophoresis, demonstrating that cultured rice cells respond to high magnetic field stress by changing their protein patterns.
