英文摘要Long-term monoculture (LTM) decreases the yield and quality of peanut, even resulting in changes in the microbial community. However, the effect of LTM on peanut rhizobial communities has still not been elucidated. In this study, we isolated and characterized peanut rhizobia from 6 sampling plots with different monoculture cropping durations. The community structure and diversity index for each sampling site were analyzed, and the correlations between a peanut rhizobium and soil characteristics were evaluated to clarify the effects on peanut rhizobial communities. The competitive abilities among representative strains were also analyzed. A total of 283 isolates were obtained from 6 sampling plots. Nineteen recA haplotypes were defined and were grouped into 8 genospecies of Bradyrhizobium, with B. liaoningense and B. ottawaense as the dominant groups in each sample. The diversity indexes of the rhizobial community decreased, and the dominant groups of B. liaoningense and B. ottawaense were enriched significantly with extended culture duration. Available potassium (AK), available phosphorus (AP), available nitrogen (AN), total nitrogen (TN) and organic carbon (OC) gradually increased with increasing monoculture duration. OC, TN, AP and AK were the main soil characteristics affecting the distribution of rhizobial genospecies in the samples. A competitive nodulation test indicated that B. liaoningense presented an excellent competitive ability, which was congruent with its high isolation frequency. This study revealed that soil characteristics and the competitive ability of rhizobia shape the symbiotic rhizobial community and provides information on community formation and the biogeographic properties of rhizobia.
