title: Nicotine-induced inhibition of lycopene cyclization in Phaseolus vulgaris cotyledons.
abstract: The complete nicotine inhibition of lycopene cyclization during light-induced carotenogenesis in excised bean cotyledons was achieved. The inhibitory effect was easily reversible and removal of nicotine has allowed synthesis of the normal cyclic carotenoids.
