Abstract

We report the identification and cloning of an ntrA-like (glnF rpoN) gene of Rhizobium meliloti and show that the R. meliloti ntrA product (NtrA) is required for C₄-dicarboxylate transport as well as for nitrate assimilation and symbiotic nitrogen fixation. DNA sequence analysis showed that R. meliloti NtrA is 38% homologous with Klebsiella pneumoniae NtrA. Subcloning and complementation analysis suggested that the R. meliloti ntrA promoter lies within 125 base pairs of the initiation codon and may be constitutively expressed.
