   opines
   Carbon compounds produced by crown galls and hairy roots induced by Agrobacterium tumefaciens > Agrobacterium tumefaciens and A. rhizogenes respectively. They are utilized as nutritional sources by Agrobacterium strains that induced the growth and are, in some cases, chemoattractants. Chemotactic activity seems to be specific for plasmids carrying the relevant opine synthase gene. Octopine, nopaline, mannopine and agrocinopines A and B are examples.

   Opines
   `Opines` are low molecular weight compounds found in plant crown gall tumors produced by the parasitic bacterium `Agrobacterium`. Opine biosynthesis is catalyzed by specific enzymes encoded by genes contained in a small segment of DNA (known as the T-DNA, for 'transfer DNA') inserted by the bacterium in the plant genome. The opines are used by the bacterium as an important source of carbon and energy. Each strain of `Agrobacterium` induces and ca...
