Abstract excerpt
Among the Frankia strains capable of establishing a nitrogen-fixing symbiosis with actinorrhizal plants, in planta sporangial formation is not universal and has led to the distinction between spore-positive (Sp+) and spore-negative (Sp-) nodules. Numerous Frankia strains have been isolated in pure culture from Sp+ nodules of different host plants, but, although they were able to reinfect their respective host...
