摘要：

Anthocyanin synthesis in maize (Zea mays L., cv. ganga safed) under white and UV-B light has been investigated after pretreatment of seedlings with flavin mononucleotide (FMN) and inhibitors of flavin photoreactions. UV-B enhanced synthesis of anthocyanin compared to white light, and this enhancement was further promoted by flavin mononucleotide (FMN). Salicyl hydroxamic acid, sodium azide and potassium iodide, which interfere with the photoreactions of flavin, inhibit UV-B-induced and FMN-promoted anthocyanin synthesis. A flavin may be involved as a photoreceptor of UV-B radiation for anthocyanin synthesis in maize.
