Survey of Chickpea Rhizobia diversity in Portugal reveals the predominance of species distinct from Mesorhizobium ciceri and Mesorhizobium mediterraneum.

abstract：:Nutrient or niche-based competition among bacteria is a widespread phenomenon in the natural environment. Such interspecies interactions are often mediated by secreted soluble factors and/or direct cell-cell contact. As ubiquitous soil bacteria, Myxococcus species are able to produce a variety of bioactive secondary m...
