Tumor formation was studied in inbred radish lines that produce tumors on plant roots during flowering. In all radish lines under consideration, the sequences homologous to oncogenes tmr/tml of Agrobacterium tumefaciens were revealed by Southern hybridization. No sequences homologous to the tms locus of A. tumefaciens and the oncogenes of A. rhizogenes were determined. It was found that auxin sensitivity and the tumor-producing capacity were coinherited. We suggest that tumor phenotype arise as a result of a combination between agrobacterial "cytokinin" oncogenes and certain alleles of "auxin" radish genes.
对开花期在植物根部产生肿瘤的自交系萝卜进行了肿瘤形成研究。在所研究的所有萝卜品系中，通过Southern杂交揭示了与根癌农杆菌致癌基因tmr/tml同源的序列。未检测到与根癌农杆菌tms位点和发根农杆菌致癌基因同源的序列。发现生长素敏感性和肿瘤形成能力是共同遗传的。我们认为肿瘤表型是由农杆菌“细胞分裂素”致癌基因与萝卜“生长素”基因的某些等位基因组合产生的。
