Fig. 9From: A simplified synthetic community rescues Astragalus mongholicus from root rot disease by activating plant-induced systemic resistanceEffects of different synthetic communities on the ISR of Astragalus. JA contents and PAL, POD, PPO, LOX, and chitinase activities of plants on the 5th day after inoculation with sterile water, SCI, SCII, SCIII, and different mixing ratios of four bacterial species. The letters above the bars denote differences based on Duncan’s multiple range test (n = 3, P < 0.05). JA, jasmonic acid; PAL, phenylalanine ammonia lyase; PPO, polyphenol oxidase; POD, peroxidase; LOX, lipoxygenase; ISR, induced systemic resistance; 10:1, Stenotrophomonas:Rhizobium:Ochrobactrum:Advenella = 10:10:1:1; 100:1, Stenotrophomonas:Rhizobium:Ochrobactrum:Advenella = 100:100:1:1; 600:1, Stenotrophomonas:Rhizobium:Ochrobactrum:Advenella = 600:200:10:1Back to article page
