特定波长的光可以对植物产生各种生理变化，包括对病害发生的反应。为了确定特定的光波长对恶臭假单胞菌229引起的腐烂病是否有影响，在发光二极管(LED)的窄波长范围内(包括红色(650-660)、远红(720-730)和蓝色(440-450 nm))或从日光荧光灯泡的宽波长范围内萌发大豆幼苗。对照组由在黑暗中萌发的大豆芽组成。大豆芽在不同条件下萌发5d后，接种恶臭疫霉229，连续5d观察发病情况。与其他条件下生长的幼苗相比，红光照射下的萌芽对恶臭疫霉229的抗性增强。红光下萌发的大豆幼苗积累了较高水平的水杨酸，同时伴随着生物合成基因ICS和病程相关基因PR-1的上调，这表明红光照射下大豆芽中水杨酸的从头合成是通过SA的作用诱导的。综上所述，这些数据表明，只有窄范围的红光才能诱导大豆幼苗产生抗病能力，这种抗性受SA依赖的途径调节，该途径通过SA的从头合成和PR基因的上调来调节。
Specific wavelengths of light can exert various physiological changes in plants, including effects on responses to disease incidence. To determine whether specific light wavelength had effects on rotting disease caused by Pseudomonas putida 229, soybean sprouts were germinated under a narrow range of wavelengths from light emitting diodes (LEDs), including red (650–660), far red (720–730) and blue (440–450 nm) or broad range of wavelength from daylight fluorescence bulbs. The controls were composed of soybean sprouts germinated in darkness. After germination under different conditions for 5 days, the soybean sprouts were inoculated with P. putida 229 and the disease incidence was observed for 5 days. The sprouts exposed to red light showed increased resistance against P. putida 229 relative to those grown under other conditions. Soybean sprouts germinated under red light accumulated high levels of salicylic acid (SA) accompanied with up-regulation of the biosynthetic gene ICS and the pathogenesis- related (PR) gene PR-1, indicating that the resistance was induced by the action of SA via de novo synthesis of SA in the soybean sprouts by red light irradiation. Taken together, these data suggest that only the narrow range of red light can induce disease resistance in soybean sprouts, regulated by the SA-dependent pathway via the de novo synthesis of SA and up-regulation of PR genes.
