We recognize that levels of different amino acids will vary and depend on factors such as plant growth conditions, plant genotype, plant growth stage, as well as plant organ; yet, our study did examine root exudates from plants from three distinct orders while murine models are restricted to a single host (mouse) that carry a dysfunctional Slc1 1a1 allele which makes them highly susceptible to systemic Salmonella infections. This evidence concerns the gene MCHR1 and Salmonella Infections.
