| 摘 要： | 多酚氧化酶(polyphenol oxidase,PPO)是引起面条等面制食品颜色褐变的主要因素,研究小麦多酚氧化酶活性的遗传规律及其与面团色泽的关系对改良面粉色泽具有重要意义.多酚氧化酶活性是受多基因控制、且遗传力低的数量性状,易受环境条件影响,发掘可应用于小麦多酚氧化酶活性辅助选择的分子标记,将有助于小麦面粉颜色性状的遗传改良.本文综述了小麦多酚氧化酶的生理功能及作用机理,重点阐述了小麦多酚氧化酶的基因定位、分子标记及遗传分析对低多酚氧化酶活性小麦新品种选育及遗传研究的意义.

| Abstract: | Polyphenol oxidase(PPO) is a major factor causing undesirable brown discoloration of wheat-based end products such as noodles.It is important to study the relation between PPO genetic law and color of wheat dough.PPO activity is a quantitative character controlled by multigene,with low heritability.It is important to identify molecular markers associated with PPO activity for marker-assisted selection(MAS) in genetic improvement of wheat flour.The physiological function and action mechanism of wheat PPO were reviewed in this paper,with focuses on some important contents,such as gene localization, molecular markers,genetics analysis and their meanings to the new wheat variety breeding of low PPO activities and genetics research. |
