Coexistence of Burkholderia, Cupriavidus and Rhizobium sp. nodule bacteria on two Mimosa spp. in Costa Rica

Article Abstract:

16S rRNA and 23S rRNA gene sequencing, PCR assays and inoculation experiments are used to analyze the symbiotic interaction of nodule bacteria with four mimosoid legumes in Costa Rica. Results revealed that both Cupriavidus and Rhizobium spp. resulted in significantly higher plant growth and nodule nitrogenase activity relative to plant performance with strains of Rhizobium.

Monophyly of nodA and nifH genes across Texan and Costa Rican populations of Cupriavidus nodule symbionts

Article Abstract:

Nodule bacteria associated with the legume Mimosa asperata in south Texas was analysed. Results suggest that all Cupriavidus nodule symbionts formed a strongly supported monophyletic group in both the nodA and nifH phylogenies.
