Abstract:

Leguminosae, as important food and cash crops, have been widely valued. Rhizobia are gram-negative bacilli which are ubiquitous in soil, and can form symbiotic nitrogen fixation system with legume plants. Rhizobium can not only increase the yield of plants, but also have no effect on the surrounding ecological environment. The symbiotic system of Rhizobium and leguminous plants has the highest biological nitrogen fixation efficiency, accounting for more than 65% of the total biological nitrogen fixation. The in-depth study of the symbiotic nitrogen fixation system is beneficial to the sustainable development of China’s agriculture. In recent years, more and more scholars have been involved in the classification, identification and application of Rhizobium. In this paper, the classification, morphological level, physiological and biochemical level, cell components, nucleic acid molecular level identification and application of Rhizobium are reviewed, which could provide references for the practical application of Rhizobium.

Key words: Leguminosae, Rhizobium, taxonomy, identification, application
