NITROGEN METABOLISM IN RIZOSPHERIC BACTERIA

We study the molecular basis and regulation of microaerobic respiration and denitrification processes in endosymbiotic bacteria of legumes, both as free-living and in the plant-bacteria-environment interaction. Our aim is to analyze the relationships between atmospheric dinitrogen fixation and denitrification, characterize key regulators involved in these processes, reduce pollution of nitrate in soil and water,diminish nitrous oxide emissions from agricultural soils to the atmosphere, to analyze the biodiversity of bacterita a involved in the nitrogen cycle and reduce the effect of abiotic stresses exerted on the symbiosis.
