Is an oxidative burst and its attenuation by bacterial peroxidase activity required for optimal establishment of the Arachis hypogaea-Bradyrhizobium sp . symbiosis?
We demonstrated for the first time that the oxidative burst triggered at the early events of the symbiotic interaction in peanut, is a prerequisite for the efficient development of root nodules, and that the antioxidant system of bradyrhizobial peanut symbionts, particularly the activity of peroxidases, is counteracting this oxidative burst for the successful establishment of the symbiosis.
Our findings showed that administration of ghrelin may be useful in reducing blood and brain oxidative stress in normobaric hypoxia condition.
