nopaline, n. Biochem.|ˈnəʊpəliːn|
[a. F. nopaline (A. Goldman et al. 1969, in Compt. Rend. CCLXVIII. D. 852), f. nopal nopal n.: see -ine5.]
An opine, C11H20N4O4 , synthesized by plant cells infected by some tumour-inducing plasmids present in the crown gall pathogen Agrobacterium tumefaciens. Cf. octopine n.
1972Plant Physiol. XLIX. 135/1 Nopaline-producing tumors induced by strain T-37 responded to lysopine and octopine as well as to nopaline. 1977Nature 10 Feb. 561/1 Nopaline is not commercially available and this restricts its use. 1983Sci. Amer. June 36/3 One [finding] was that whether a tumor synthesizes octopine or nopaline depends not on the species of the host plant but on the strain of the bacterium that induces the tumor. 1988Plant cell Physiol. XXIX. 777/2 In the present study, we tried to correlate the in vitro ent-kaurene synthesizing capacity to the endogenous GA [sc. gibberellin] levels of shoot forming, nopaline-type tobacco crown galls. |
