Identification of a malate chemoreceptor in Pseudomonas aeruginosa by screening for chemotaxis defects in an energy taxis-deficient mutant.

abstract：: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+ nod...
