“…Rhizobia are peritrichously or subpolarly flagellated bacteria [32] that can react to chemical gradients. Many substances present in root exudate such as carbohydrates, amino acids, carboxylic acids and phenolic compounds have been identified as chemoattractants that will promote the colonization of the rhizosphere [33][34][35][36][37][38][39][40][41].…”

The host range may extend beyond that given here and may differ among species of a genus. c For Bradyrhizobium strains other than B. ]aponicum it was suggested that they be referred to as Bradyrhizobium sp. with the name of the host plant in parentheses immediately following [218], e.g., Bradyrhizobium sp. (Parasponia). d And further references therein. The older designation was used throughout this review.f Probably, this strain belongs to R. fredii [25]. In this review no differentiation is made between the almost isogenic strains Rhizobiurn sp. strain NGR234 and strain MPIK3030 [227].g See text for a recent dispute. 42tractant [48]. The nodulation genes are probably not involved in this chemotactic response [49].Chemotaxis towards nod gene-inducing flavonoids was also reported for Rhizobium leguminosarum strains [33,50]. In this case, the symbiotic plasmid, which carries all known nod genes, was beneficial, but not essential, for chemotaxis [50]. In contrast, none or only a very weak chemotaxis towards inducers of nod gene transcription was detected in B. japonicum [34,40].
