Molecular mechamisms of specific interactions in bromovirus infections in rice

在水稻品种与溴菊花叶病毒（BMV）株系的系统侵染中观察到特异性相互作用。我们已经确定了参与这种相互作用的水稻和BMV因子。遗传分析表明，粳稻品种对BMV的抗性反应受单个显性位点（600 kb区域）控制。突变分析表明，水稻系统感染BMV菌株的差异是在细胞间运动水平上由BMV聚合酶蛋白2a c端非保守区几个错义突变决定的。

Specific interactions are observed in systemic infection of rice varieties with Brome mosaic virus (BMV) strains. We have identified rice and BMV factors that are involved in such interactions. Genetic analysis suggested that resistance responses of japonica rice varieties to BMV were controlled by a single dominant locus (600 kb region). Mutational analyses suggested that differences in systemic infection of rice with BMV strains were determined at the level of intercellular movement by several missense mutations within the C-terminal non-conserved region of BMV polymerase protein 2a.
