Crown-gall, one of the "plant cancer" is induced in the presence of a soil bacterium Agrobacterium tumefaciens which elaborates a Tumor inducing principle (T.I.P.), the nature of which is unknown. Several informations suggest that some DNA sequences of bacterial origin are included in tumorous cells of tissue cultures. A ribonuclease inhibits induction. An RNA extracted from Agrobacterium induces some hyperplasia transplantable by graft.
冠瘿病是一种“植物癌症”,它是在土壤细菌根癌土壤杆菌存在的情况下诱发的,这种细菌能产生一种致瘤因子(T.I.P.),其本质尚不清楚。一些信息表明,细菌来源的某些DNA序列包含在组织培养的肿瘤细胞中。一种核糖核酸酶可抑制诱导作用。从根癌土壤杆菌中提取的一种RNA能诱导一些可通过嫁接移植的增生。
