Abstract
The mechanism of biological control of Phytophthora blight by treatment with mangrove endophy-tic bacterium RS261 was studied. Tagged by the resistance to rifampicin (300 μg/mL), the strain RS261 could colonize many plants, such as capsicum, tomato, eggplant, et al. An obvious promotion on pepper growth occurred after watering roots with strain RS261. The metabolites of strain RS261 showed strong inhibitory activity against mycelial growth and sporangia production of P.capsici. Inoculation with P.capsici considerably increased the content of MDA and the activities of SOD, CAT and POD in the capsicum. However, when co-inoculated with strain RS261 and P.capsici at the same time, the MDA content and SOD, POD and CAT activities were all lower than those inoculated with pathogen only. In addition, treatment by co-inoculation increased PAL activity, and the induced PAL activity might enhance anti-disease capability of the plants.
