Unlike most bacteria, the nitrogen-fixing rice-associated Pseudomonas stutzeri A15 disposes of three different nitrate reductases that enable conversion of nitrate to nitrite through three physiologically distinct processes, called nitrate assimilation, nitrate respiration and nitrate dissimilation. To study the role of nitrate respiration in rhizosphere fitness, a Pseudomonas stutzeri narG mutant was constructed and characterized by assessing its growth characteristics and whole-cell nitrate reductase activity in different oxygen tensions. Unexpectedly, the Pseudomonas stutzeri A15 narG mutant appeared to be a better root colonizer, outcompeting the wild type strain in a wheat and rice hydroponic system.
