Resistance and Susceptibility of Carrot Roots to Crown-gall Tumor Formation.
Crown-gall tumor cells induced by Agrobacterium tumefaciens (Sm. and Town.) Conn develop from normal plant cells by the action on them, in sequence, of several causal factors.1 Inoculations of susceptible species frequently result in fairly uniform tumors in 100 per cent of the trials. Inoculations of other plant species are not always successful or may result in tumors showing considerable siz...
متن کاملRelative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile
G. Guzmán, B.A. Latorre, R. Torres, and W.F. Wilcox. 2007. Relative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile. Cien. Inv. Agr. 34(1):31-40. Crown gall (Agrobacterium tumefaciens) and Phytophthora root and crown rot (PRCR), caused by P. cryptogea, are two major limiting factors affecting peach (Prunus persica) production in Chile. At present, N...
متن کاملRecovery of crown-gall tumor cells.
nant animal cells are distinguished from healthy or inflaznmstory cells. In emphasizing the perma nency of the cellular alteration, Kidd (6) states that “Cancercells remain such until they die . . they never turn back en masse towards the benign or normal state. . . .“The inability to accomplish a reversal of malignant to normal cells under con trolled conditions has, however, served as a s...
متن کاملRNAi-mediated oncogene silencing confers resistance to crown gall tumorigenesis.
Crown gall disease, caused by the soil bacterium Agrobacterium tumefaciens, results in significant economic losses in perennial crops worldwide. A. tumefaciens is one of the few organisms with a well characterized horizontal gene transfer system, possessing a suite of oncogenes that, when integrated into the plant genome, orchestrate de novo auxin and cytokinin biosynthesis to generate tumors. ...
متن کاملCrown gall teratoma formation is plasmid and plant controlled.
Experiments using different species of the plant Nicotiana and strains of the bacterium Agrobacterium tumefaciens showed that teratoma formation from crown galls was dependent on the combination of bacterial Ti plasmid and host plant used.
