Proteomic analysis dissects the impact of nodulation and biological nitrogen fixation on Vicia faba root nodule physiology

Symbiotic nitroegn fixation in functional (Fix+) and non-functional (Fix-) nodules of Vicia faba infected with Rhizobium leguminosarum was investigated using label-free shotgun tandem MS. Proteins involved in symbiotic nitrogen fixation and maintenance of the symbiosis were identified.
