WebSep 29, 2005 · Ti plasmids are generally referred to by the opines they can catabolize, and the two best studied are often referred to as the nopaline-type plasmid originally found in strain C58 and the octopine-type Ti plasmid, which is found in virtually identical forms in strains such as A6, B6, 15955, Ach5, and R10. WebOct 20, 2024 · A sizable extrachromosomal plasmid during these bacteria was discovered to be accountable for its tumor-inducing capacity and it was, therefore, known as Ti-plasmid (36). Bacteria-free crown gall cells could be cultured even without the phytohormones like auxines and cytokinines, which hormone-independent growth defines tumorous …

It was of interest to determine whether the membrane itself was altered … WebIn ‘octopine’-type Ti plasmids, octopine binds to and activates OccR, the LysR-type regulator of an octopine catabolism operon, to induce expression of the operon. traR is the last gene in this operon and so is induced when the bacteria catabolise octopine ( Habeeb et al., 1991; Fig. 2 ). In nopaline-type Ti plasmids, accR (agrocinopine ...
WebNov 19, 1980 · For the nopaline Ti-plasmids both left-hand and right-hand borders were found to be constant. For the octopine plasmid the left border was constant and at least two classes of right-hand borders were found. Upon redifferentiation of the transformed plant cells, the T-DNA was found to be conserved in all somatic cells examined.
