| 摘 要： | 烟草中多酚氧化酶(PPO)介导的褐交会影响烟叶和烟丝的色泽和内在质量，因此对其特性的研究，以及活性的控制成为多年来的研究热点。笔者从PPO生物发生模型，分子结构，生物化学和光谱学特征及其与植物抗病和机械损伤的关系，多酚氧化酶的抑制，多酚氧化酶的应用等方面，对近几年来烟草中PPO研究的最新成果进行了回顾和总结，对一些有争议的问题进行了探讨，并对未来PPO研究的方向和领域进行了展望。

| Abstract: | Browning reaction mediated by polyphenol oxidase (PPO)in tobacco can form unpleasant color,which is harmful to tobacco leaf quality.So many researches on the properties and activity control of PPO have been carried out.The recent research achievements about tobacco PPO with respect to its biological development model,molecular structure,biochemical and spectral properties,the relations between PPO and plant resistance to pathogen and wounding,and activity control of PPO are reviewed in this paper.In addition,the future work and application of tobacco PPO are discussed and forecasted. |
