MetabolomicsExometabolomic-enabled discovery of compounds associated with Escherichia coli O157:H7 population dynamics in the lettuce phyllosphere

Contamination of fresh produce with human pathogens remains a serious public health and economic concerns due to the absence of effective kill steps in the farm-to-fork chain. In particular, the pathogenic Escherichia coli O157:H7 has been implicated in multiple illness outbreaks linked to lettuc...

TranscriptomicsGene Expression in Arabidopsis thaliana Guard Cells
Stomata are formed by a pair of specialized guard cells that control the opening and closing of the stomatal pores on the leaf surface. These pores are the main route for microbe penetration into leaves. However, plants show a remarkable ability to close the pore when sensing the presence of microbi...

MetabolomicsSalmonella enterica and Pseudomonas syringe uniquely alter the exometabolomic profile of the Arabidopsis leaf surface
To successfully colonize healthy plants, bacterial pathogens must overcome stressful conditions on the leaf surface before entering the leaf tissues through natural openings. In this study, we developed an approach to examine the exometabolomic profiles of the leaf surface when exposing plants with ...
