Pararhizobiumiin

Pararhizobium is a genus of Gram-negative soil bacteria belonging to the family Rhizobiaceae. These bacteria are known for their ability to form symbiotic relationships with leguminous plants, playing a crucial role in nitrogen fixation. Like other rhizobia, Pararhizobium can infect the roots of legumes and induce the formation of root nodules. Within these nodules, the bacteria convert atmospheric nitrogen (N2) into ammonia (NH3), a form that plants can readily utilize for growth. This symbiotic process is vital for nutrient cycling in many ecosystems and is a cornerstone of sustainable agriculture.

Species within the genus Pararhizobium are typically motile and possess peritrichous flagella. They are aerobic, meaning they require oxygen for respiration. Their metabolic capabilities allow them to utilize a range of carbon sources. Genetic studies have revealed distinct phylogenetic relationships that differentiate Pararhizobium from closely related genera like Rhizobium and Bradyrhizobium. Research on Pararhizobium contributes to our understanding of microbial ecology, plant-microbe interactions, and the genetic basis of nitrogen fixation, with potential applications in improving crop yields and reducing the need for synthetic nitrogen fertilizers.
