英文摘要	Fusarium wilt caused by Fusarium oxysporum f. sp. phaseoli (Fop) is one of the most serious diseases of common bean (Phaseolus vulgaris L.) and is especially prevalent in China. In this study, we demonstrated that exogenous application of 2 mM salicylic acid (SA) by leaf spraying could induce resistance against Fop in common beans. Accumulation of free and conjugated SA in roots was detected by HPLC analysis and compared. After 168 h of daily SA treatment, the free SA level in roots was eight times higher than in control plants. However, the conjugated SA level reached a peak at 72 h of SA treatment, which was nine times higher than in control plants, and then sharply declined at 168 h. The activities of phenylalanine ammonia lyase (PAL, EC 4.3.1.5) and peroxidases (POX, EC 1.11.1.7) in roots were 9.4 and 6.3 times higher than in control plants after 168 h of SA treatment, respectively. H2O2 and O-2(-) levels reached 2.6 and 13.6 times higher, respectively, than in the control plants at 168 h after SA treatment. Host reactions of SA-treated plant roots infected by Fop observed in microscopy included the deposition of electron-dense materials along the secondary walls. However, untreated inoculated plants showed marked cell wall degradation and total cytoplasm disorganization of root cells. These results indicated that SA applied to foliar tissue is capable of enhancing the systemic acquired resistance of common bean roots to infection by Fop.
