When normal shoots which had been regenerated from tobacco genetic tumor cultured in the dark were cut, tumorous tissues were again induced on the cut segments. Morphological examination of the segments, 5 days and 15days after cutting, in a comparison with normally regenerated shoots, revealed active cell division in vascular-bundle tissue and formation of primordial teratoma-like structures in the induced tumorous tissues. Endogeneous IAA remained at a constant, low level throughout the tumorigenetic process. Proteins from each step of tumorigenesis were separated by two-dimensional electrophoresis on mini-gels and visualized by silver staining. Twenty-seven polypeptides showed qualitative or quantitative changes during the tumorigenetic process. These results are discussed in relation to the development of tobacco genetic tumor.
