CC   -!- FUNCTION: NodD regulates the expression of the nodABCFE genes which
CC       encode other nodulation proteins. NodD is also a negative regulator of
CC       its own expression. Binds flavonoids as inducers.
CC   -!- MISCELLANEOUS: There are at least two nodD genes in B.elkanii.
CC   -!- SIMILARITY: Belongs to the LysR transcriptional regulatory family.
CC       {ECO:0000305}.
