Calicotome villosa
is a spontaneous Mediterranean legume that can be a good candidate as pioneer plants to limit regression of vegetation cover and loss of biodiversity in Tunisian arid soils. In order to grow legumes in such soils, pairing rhizobia and nodule associated bacteria (NAB) might provide numerous advantages. In this work, cultivable biodiversity of rhizobial symbionts and NAB in nodules of
C. villosa
plants growing in five arid regions of south Tunisia was characterized. Phylogenetic analysis using 16S rDNA gene,

C. villosa
plants were inoculated with representative rhizobia of each phylogenetic group and co-inoculated with the same rhizobia and strain
CT7
.15. Compared with single rhizobia inoculation, co-inoculation significantly improved plant growth and nodulation, ameliorated plant physiological state and increased nitrogen content in the plants, independently of the rhizobia used. These results support the benefits of pairing rhizobia and selected NAB to promote legume growth in arid or degraded soils.
