[Mechanism of action of beta-ionone on the carotene-synthesizing enzymes of Blakeslea trispora].
The addition of beta-ionone to the growing culture of Blakeslea trispora stimulates the synthesis of carotene, protein, and RNA. The experiments with the addition to the growth medium of an inhibitor of translation (cycloheximide) and an inhibitor of transcription (actinomycin D), in the presence of beta-ionone, suggest that beta-ionone stimulates the synthesis of carotene-forming enzymes de novo in B1. trispora, this effect being manifested at the level of translation of the templates in the ribosomes.
