Abstract
It was shown that life span of wild type strain Canton-S increased after low doze gamma-irradiation. It was revealed the decrease of life span after irradiation in Drosophila mutants with defects of DNA damage sensation and repair genes mei-9 and mei-41, both in homozygous and heterozygous lines. In mei-41 line males' lives longer than females in contrast to other lines.
摘要
结果表明，低剂量γ射线照射后野生型品系Canton-S的寿命延长。研究发现，DNA损伤感知和修复基因mei-9和mei-41存在缺陷的果蝇突变体，无论是纯合子还是杂合子品系，在辐射后的寿命都会缩短。与其他品系不同，在mei-41品系中，雄性的寿命比雌性长。
