The effects of hormones and inhibitors on amaranthin synthesis in seedlings of Amaranthus tricolor

Abstract
Both gibberellic acid and abscisic acid inhibit the light induced synthesis of amaranthin in Amaranthus tricolor seedlings. The auxin, indolyl-3-acetic acid has no effect. The protein/RNA inhibitors, cycloheximide and 8-azaguanine, also reduced the levels of amaranthin produced.
