Studies of conditions for the growth of callus tissue of C. roseus were first reported in 1962 (114) by Babcock and Carew, and analytical work commenced when Carew and co-workers (115) demonstrated that in the presence of 0.5 mg/liter kinetin callus tissue grew rapidly and probably produced vindoline (3), as well as a number of other alkaloids. At the same time, a group at Eli Lilly (116) reported an analysis of the alkaloids of crown gall cultures which had been maintained by Hildebrandt s group...

Plant tumors result from uncontrolled hormone production. Crown gall tumors, for example, are due to the infection of plant wounds by certain strains of Agrobacterium. These bacteria carry a large plasmid, the tumor-inducing, or T, plasmid, part of which is incorporated into the plant genome. This DNA encodes several genes that stimu-...

The crown-gall tumour that is induced by certain strains of this micro-organism contains a number of interesting amino-acids, but agropine (36). a novel bicyclic derivative of glutamic acid, has recently been isolated and is present in quantities of up to 7% of the dry weight of the tumour.43...
