Employing a novel two-part screen, we identified Sinorhizobium meliloti mutants that were both sensitive to hydrogen peroxide and symbiotically defective on the host plant Medicago sativa. The mutations affect a wide variety of cellular processes and represent both novel and previously identified genes important in symbiosis.
通过采用一种新颖的两部分筛选方法,我们鉴定出了苜蓿中华根瘤菌突变体,这些突变体对过氧化氢敏感,并且在宿主植物紫花苜蓿上共生缺陷。这些突变影响了多种细胞过程,代表了在共生中重要的新基因和先前已鉴定的基因。
