Rhizobium japonicum grown anaerobically with nitrate produced several factors capable of transferring electrons from spinach chloroplasts lacking photosystem II to soybean root nodule nitrogenase. The same organism grown aerobically produced no factors with detectable activity. It is concluded that the bacterium is potentially capable of producing these proteins in the low oxygen conditions of the leguminous root nodule.
根瘤菌在厌氧条件下利用硝酸盐产生了几种因子,这些因子能够将缺乏光系统 II 的菠菜叶绿体中的电子转移到大豆根瘤中的氮酶。同样的生物体在有氧条件下生长时,没有产生具有可检测活性的因子。因此,可以得出结论,在豆科植物根瘤的低氧条件下,这种细菌具有产生这些蛋白质的潜力。
