Effects of γ-irradiation on true leave formation in wild-type and mutant plants. Wild-type and mutant seeds were exposed to gamma-radiation at 0 (mock-irradiation) or 100 Gy, and sown on soil. These images were captured 10 days after γ-irradiation. Bar = 1 mm. All pictures were taken at the same magnification. Arrows show true leaves with abnormal shapes produced after γ-irradiation.
