摘 要:

水稻(Oryza sativa)的生长发育受各种病害的影响, 由革兰氏阴性菌稻黄单胞菌(Xanthomonas oryzae pv. oryzae, Xoo)所引起的白叶枯病是影响水稻产量最严重的细菌病之一。传统的方法很难防治白叶枯病, 而应用白叶枯病抗性基因是当今农业生产上最有效、经济和环保的防治白叶枯病的方法。本论文对当前已克隆的16个白叶枯病抗性基因进行了分类和功能概述, 重点阐述第一个被克隆的抗白叶枯病数量性状基因NBS8R以及具有高抗、广谱、持久和耐热的Xa7基因, 同时也对白叶枯病抗性育种方法的应用进行了概述。最后, 本综述对当前白叶枯病抗性基因育种存在的问题及解决措施作出展望。

Abstract:

The growth and development of rice are affected by various diseases. Bacterial blight caused by the Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious bacterial disease affecting rice yield. Traditional methods are difficult to control bacterial blight. The application of bacterial blight resistance gene is the most effective, economical and environment-safe method in current agricultural production. In this review, we described the classification and biological functions of sixteen cloned bacterial blight resistance genes, and emphasized on the first cloned quantitative gene NBS8R as well as the Xa7 with high resistance, broad spectrum, persistence and heat resistance. In addition, the application of bacterial blight resistance breeding methods was also summarized. Finally, we proposed the current problems and solutions for bacterial blight resistance gene breeding.
