Proteomics analysis of Phytophthora alni infection in Frankia alni and Alnus glutinosa symbiotic nodules.

The proteomics analysis of the nitrogen-fixin bacterium Frankia alni, the tree Alnus glutinosa (Alder), and the oomycete plant pathogen Phytophthora alni was carried out by shotgun proteomics from nodules to establish the defence mechanisms of the symbiont during an infection.
