Light is critical for supplying carbon to the energetically expensive, nitrogen-fixing symbiosis between legumes and rhizobia. I have already showed that root nodule formation is photomorphogenetically controlled by sensing the red/far red (R/FR) ratio through JA signaling. In this study, I found that condition of light treatment for increase of the number of root nodule of soybean. As expected, when three day-old soybean plants were treated by FR for 3 weeks, root nodule number was significantly decreased compared with non-treated control plants. However, root nodule number was significantly increased by 3 weeks FR treatment plus 4 weeks natural sunlight treatment compared with non-treated soybean. If this light treatment is applied for soybean production, there is a possibility that soybean yield increase due to the enhancement of root nodule nitrogen fixation by the symbiosis with Bradyrhizobium japonicum.

光对于为豆科植物和根瘤菌之间能量昂贵的固氮共生体提供碳至关重要。我已经证明，根瘤的形成是通过 JA 信号传导感测红光/远红光 (R/FR) 比率来进行光形态发生控制的。在这项研究中，我发现光处理条件可以增加大豆根瘤的数量。正如预期的那样，当三天大的大豆植物用 FR 处理 3 周时，与未处理的对照植物相比，根瘤数量显着减少。然而，与未处理的大豆相比，3周FR处理加4周自然阳光处理的根瘤数量显着增加。如果将这种光处理应用于大豆生产，则由于与慢生根瘤菌共生而增强根瘤固氮作用，大豆产量有可能增加。
