A Bradyrhizobium japonicum gene essential for nodulation competitiveness is differentially regulated from two promoters.

Molecular plant-microbe interactions : MPMI - 1 Jan 2000

Chun J Y, Stacey G

Abstract excerpt

We report the identification and nucleotide sequence of a new symbiotic gene (nfeC) from the soybean root nodule bacterium, Bradyrhizobium japonicum. A Tn5 insertion (NAD14) in this gene did not affect nitrogen fixation but caused a significant delay in soybean nodulation. In addition, this mutant exhibited a reduction in its competitive ability to nodulate soybean when coinoculated with the wild type. Sequence...
