The three strains used in this study.
| Strains | Isolation sites | 16S rRNA | recA | nodC |
|---|---|---|---|---|
| Bradyrhizobium elkanii H255 | Jiangfeng, Hainan Province, China | KX159762 | KX159756 | KX159752 |
| Rhizobium multihospitium –like HT221 | Pingxiang City, Guangxi Province, China | KX159767 | KX159761 | – |
| Burkholderia pyrrocinia–like H022238 | Sanya City, Hainan Province, China | KX159766 | KX159760 | KX159755* |
The amplifying primers and conditions of 16S rRNA, recA, and nodC were described by DeLong (1992), Vinuesa et al. (2005), and Laguerre et al. (2001), respectively. –, not detected.
