Abstract:
In crude protein extracts of aseptically grown plantlets of Datura innoxia ornithine carbamoyltransferase was detected. The ornithine carbamoyltransferase of plant extracts was inhibited by phaseolotoxin. The level of this inhibition was dependent on the concentration of the toxin applied. Subsequent accumulation of ornithine in plant vegetative parts was observed. Phaseolotoxin influenced both the vitability and alkaloid accumulation of treated plants.
