Abstract

SUMMARY: The transciption of genes that function in N fixation () and nitrogen assimilation () in is coordinately induced in response to O limitation as well as symbiotic development. We have determined the relative steady-state mRNA levels for the and transcription units in bradyrhizobial cells grown under a variety of levels of aerobiosis and in cells isolated from soybean root nodules. All three transcripts are found in cells grown in a rich medium sparged with O concentrations of 5 % (v/v) or less. This expression is qualitatively similar to that observed for during symbiotic development. Potential physiological mechanisms for the coordinate control of these genes are discussed.
