Environmental and Symbiotic Microbiology Group

Grupo de Microbiología Ambiental y Simbiótica

Investigador Responsable: Esperanza Martínez-Romero, Ph.D.

How it emerged

Phaseolus vulgaris (bean)was chosen as the model to study symbiotic nitrogen fixation at CIFN. Being native to Mexico , bean offered a large diversity of bacterial symbionts and for this, biodiversity studies were undertaken to characterize them. Over the years these studies have extended to cover other beneficial bacteria associated with different plants of agronomic or forestry importance.
