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.
| 1972 Plant Physiol. XLIX. 135/1 Nopaline-producing tumors induced by strain T-37 responded to lysopine and octopine as well as to nopaline. 1977 Nature 10 Feb. 561/1 Nopaline is not commercially available and this restricts its use. 1983 Sci. 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. 1988 Plant 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. |
