Abstract
AbstractExtracts from the brown seaweeds Cystoseira myriophylloides, Laminaria digitata and Fucus spiralis were evaluated as plant defence inducers against the wild fire disease of Nicotiana benthamiana. Seeds’ imbibition in aqueous seaweed extracts (SE) results in plants with reduced disease severity. In addition, bacterial populations were significantly reduced in these plants when compared to those germinated in sterile distilled water. They primed N. benthamiana for H2O2 accumulation and for enhanced activity of several antioxidant enzymes including catalase, ascorbate peroxidase, guaiacol peroxidase and polyphenol oxidase. These results revealed that soaking of seeds in SE before sowing allows N. benthamiana to reduce pathogen attack and can be easily applied in practice.
