The Ausubel laboratory uses genetic, genomic, and chemical genetic approaches to: (1) elucidate the molecular basis of microbial pathogenesis in the bacterial pathogens Pseudomonas aeruginosa and Pseudomonas syringae and (2) identify the components of the signaling pathways involved in the host innate immune response in the plant Arabidopsis thaliana and the nematode Caenorhabditis elegans.
Identification and characterization of the Rhizobium meliloti ntrC gene: R. meliloti has separate regulatory pathways for activation of nitrogen fixation genes in free-living and symbiotic cells.
