Two types of experimental approaches designed to test the possible involvement of chimeras in the persistent but readily reversible suppression of the tumorous state and in a recovery from that state in crown gall teratomas of tobacco were investigat

A unifying concept that appears to provide an understanding of cancer as a fundamental scientific problem is presented. This concept, which was initially developed on the basis of experiments using the relatively uncomplicated plant tumor systems, no

Four neoplastic diseases of plants: crown gall, which is caused by Ti plasmid DNA; Black's wound tumor disease by an RNA virus; the Kostoff genetic tumors by chromosomal imbalance; and habituation, which results from a spontaneous activation of selec

The results reported in the present study demonstrate that oncogenicity and nopaline synthesis are differentially expressed under conditions in which the neoplastic state is persistently suppressed in crown gall teratoma tissues of tobacco. While an

1. Strains of Phytomonas stewarti that differed in virulence, colony type, physiology, and agglutination reaction were tested for ability to absorb agglutinins from immune sera. All the strains tested absorbed most of the agglutinins from both homolo

SOMEWHAT MORE than 30 years ago Magnus (1915) and Smith (1916) independently announced the discovery of a highly complex type of crown-gall tumor that contained, in addition to tumor cells, tissues and organs that showed a high degree of cellular dif
