The Latest Progress of TILLING Technique and Its Prospects in Irradiation Mutation Breeding

  • 摘要: 定向诱导基因组局部突变技术(Targeting Induced Local Lesions IN Genomes, 简称TILLINC)是一种全新的、高通量和低成本反向遗传学研究方法。近年来, 随着突变筛选技术的革新, TILLING技术平台日趋多元化, 使得TILLING技术的操作更为简单﹑快速, 并广泛应用于作物育种研究领域。简要介绍了TILLING技术平台的最新发展动态, 并初步探讨了将辐射诱变处理与TILLING高通量筛选相结合在诱变育种中的应用前景。To investigate the M1 biological effects of heavy ions irradiation on Lycopersicon esculentum Mill., its seeds were irradiated by 12C6+heavy ions (80 MeV/u) with the dosages of 30, 60, 90, 120 and 160 Gy respectively . The results showed that with doses increased gradually, germination rate and seedling rate of Lycopersicon esculentum Mill. were decreased, and the latter was lower than the former, mainly due to the inhibition of root growth.
