Abstract

To study the relationship between polyphenol oxidase （PPO） and tissue browning in Phyllostachys nigra，homologous cloning was used to obtain a partial sequence of the PPO gene in Phyllostachys nigra （named PnPPO）. The gene structure and the expression pattern in tissue cultured seedlings with different degrees of browning were checked using reverse transcription Polymerase Chain Reaction（RT-PCR）. The sequence revealed a homolog of the PPO gene in Oryza sativa and Triticum aestivum with the amino acid belonging to tyrosinase. Also，RT-PCR results showed that with high levels of browning，PnPPO had strong expression. Thus，the expression of PnPPO was related to the degree of browning.［Ch，4 fig. 15 ref.］
