Abstract

Rhizobia participate in the biological fixation of atmospheric dinitrogen in associations with their compatible host plants, supplying ~200 million tons of this element per year to the global nitrogen cycle; that is, almost a half of nitrogen compounds introduced to the environment as artificial fertilizers [6,7,8]. [...]this type of plant–microbe interaction plays a crucial role in the functioning of the biosphere since it increases soil fertility and field crops. [...]before rhizobia find compatible host plants, they have to survive in soil as free-living bacteria and are exposed to various environmental factors such as nutrient limitations, drought, salinity, temperature changes, the presence of heavy metals, and oxidative stress [14,15,16,17,18,19,20]. [...]rhizobia have developed several features and strategies that allow them to adapt to these conditions. In-silico sequence analysis showed that this gene encodes a protein belonging to the family of serine/threonine protein phosphatases (STPs), which are involved in regulation of various cellular processes in bacteria, including growth and division, motility, envelope biogenesis, biofilm formation, cell aggregation, regulation of transcription and translation, and signaling [60,61,62,63]. [...]most STPs have been characterized in Gram-positive bacteria, and only a few examples of these enzymes in Gram-negative bacteria have been reported. [...]in the present study, we have performed a comparative transcriptomic analysis of the wild-type Rt24.2 and its derivative, pssZ mutant strain Rt297, to establish a set of genes differentially expressed in these two strains.
