En la relación simbiótica que tiene lugar entre plantas leguminosas y rizobios fijadores de nitrógeno es necesaria una comunicación recíproca entre ambos organismos en la que intervienen señales químicas producidas por la planta y la bacteria. Sinorhizobium fredii HH103 es un rizobio simbionte de la soja que presenta un amplio rango de...

The question of how genotypic and ecological units arise and spread in natural microbial populations remains controversial in the field of evolutionary biology. Here, we investigated the early stages of ecological and genetic differentiation in a highly clonal sympatric Sinorhizobium meliloti population. Whole-genome sequencing revealed that a...

Bacteria can spread on surfaces to colonize new environments and access more resources. Rhizobia, a group of α- and β-Proteobacteria, establish nitrogen-fixing symbioses with legumes that rely on a complex signal interchange between the partners. Flavonoids exuded by plant roots and the bacterial transcriptional activator NodD control the...
