Eight haplotypes assigned to the Bradyrhizobium genus were identified, and the genetic diversity was conserved across regions. Sequence analyses of the IGS and the dnaK, glnII, recA, and nifH genes revealed three groups. One of them (26% of isolates) was assigned to Bradyrhizobium liaoningense. A second group (36% of isolates) was identified as B. yuanmingense but likely forms a new biovar able to nodulate soybean plants. The third lineage (38% of isolates) was different from all described Bradyrhizobium species but showed the same symbiotic genotype as B. liaoningense and B. japonicum bv. glycinearum. specialized 084 74 19 5991-5996 2008 0099-2240 https://www.documentation.ird.fr/hor/fdi:010042796 10.1128/aem.01320-08 0099-2240 [F B010042796] https://www.documentation.ird.fr/hor/fdi:010042796 https://www.documentation.ird.fr/intranet/publi/2008/10/010042796.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-11-07 2023-09-07 fdi:010042796 fre
