Response of Medicago truncatula seedlings to colonization by Salmonella enterica and Escherichia coli O157:H7.

Disease outbreaks due to the consumption of legume seedlings contaminated with human enteric bacterial pathogens like Escherichia coli O157:H7 and Salmonella enterica are reported every year. Besides contaminations occurring during food processing, pathogens present on the surface or interior of pla...
