Chemotaxis and nod Gene Activity of Bradyrhizobium japonicum in Response to Hydroxycinnamic Acids and Isoflavonoids.
In: APPLIED AND ENVIRONMENTAL MICROBIOLOGY, Vol. 57, No. 1: pp. 316-319
For Bradyrhizobiumjaponicum, the chemotactic and the nod gene-inducing effects of hydroxycinnamic acids
and two of their derivatives were compared with those of isoflavonoids. Only the hydroxycinnamic acids were
strong chemoattractants, while the other substances tested were chemotactically inactive. Besides the known
nod gene induction by isoflavonoids, a weak nod gene induction by coniferyl alcohol, chlorogenic acid, and
ferulic acid was found.
