Advances in biogeography of rhizobia

Abstract:

Rhizobia are Gram-negative bacteria that can form a nodule with specific host plants, which can transform nitrogen in the air to ammonia nitrogen for plant utilization. Studying on the biogeographical pattern of the rhizobia is not only theoretically meaningful, but also helpful to guide the selection of rhizobial inoculant. At present, with the development of molecular biotechnology, and the accumulation of rhizobia diversity research data, rhizobial biogeography has got great progress. This paper summarizes the current researches of rhizobial biogeography, and indicates the direction in future research.
