However, the size and number of colonies are less than which in anaerobic TYL medium. It can not grow in aerobic TYL and TYG media. Bifidobacterium longum can tolerate radiation dose as high as 80 Gy, which is the total dose in clinical radiotherapy. Therefore, Bifidobacterium longum has the potential to be the vector for cancer gene therapy combining radiotherapy. Besides, this is the first study to investigate the tolerance of X-ray radiation for Bifidobacterium longum.

此外，从本研究中得知Bifidobacterium longum可耐受高达80 Gy的辐射剂量（单次照射，存活分率为22 ％；以分次照射每次给予2 Gy来估算，存活分率为67％），此剂量为临床放射治疗一般给予的总剂量，因此证实Bifidobacterium longum有很大的潜力做为癌症基因治疗合并放射治疗的载具，本研究也是首篇调查Bifidobacterium longum对放射线耐受性的研究。

To understand whether the GST can protect plant from the damage of ultra-violet radiation,a UV inducible GST gene was isolated from an Arabidopsis cDNA library.The plant expression vector containing the GST cDNA was constructed and transferred into Arabidopsis thaliana plants by the Agrobacterium-mediated vacuum method.Molecular genetic analyses showed that the overexpression of the UV inducible GST could increase the tolerance of the transgenic plants to UV radiation

为了阐明GST在紫外辐射下是否对植物有保护作用，以紫外强烈诱导表达的GST cDNA为探针，筛选拟南芥cDNA文库，获得了这种GST的全长cDNA；利用此cDNA构建植物表达载体，并通过农杆菌介导法转化拟南芥，使其在拟南芥中得到大量表达；通过对转基因植株的紫外辐射耐性分析，证实了该GST的过量表达可明显增强拟南芥对紫外辐射损伤作用的耐受性。
