Abstract
Calicotome villosa is a eurioic legume with broad distribution in the south of Europe. It can grow in almost any type of soils as well as in humid and dry and nutrient deficient ecosystems. The broad distribution and eurioic nature of C. villosa may be attributed to its ability to establish symbiotic associations with plant growth promoting (PGP) bacteria housed in the nodules and rootless. This study examined legume-microbe symbiosis of C. villosa growing in two contrasted locations, hill top with high sun irradiance and drought; and a valley bottom, with low level or radiation and sufficient soil humidity for plant growth. Calicotome villosa adult plants established symbiotic in-teractions with bacteria in six genera, Pseudomonas, Stenotrophomonas, Bacillus, Paenibacillus, Brevicacterium and Rhizobium as well as one uncultured bacteria. Plants growing in the hill top had associated lower bacterial richness than those grown at the valley bottom. All strains were drought tolerant and produced siderophores, IAA, HCN and NH3 that stimulated plant performance in both, C. villosa plants and other four legumes commonly present in the understory of the shrubs communities The legumes’ capacity to selectively host symbiotic bacteria that enhance plant survival in harsh conditions partly accounts for the diverse partnerships between C. villosa plants and their symbionts, ultimately explaining the wide distribution of this plant species.
