Arabidopsis thaliana gene expression upon exposure to nanoparticles (NPs), biotic and abiotic stresses, or NPs plus ABA phytohormone, PART 1

ABSTRACT: Here we provide a set of 16 comparable transcriptome measures to monitor early changes in gene expression upon NP exposure. We evaluated A. thaliana response to 8 different types of NPs (metallic, carbonaceous and ranging from 10 to 80 nm) in comparison to biotic and abiotic stress inducers that represent most common environmental challenges for plants. Biotic stress was induced by infection with a necrotizing fungus (Alternaria brassicicola) or a hemibiotrophic bacterium (Pseudomonas syringae). Abiotic stresses induced by hypersaline conditions, drought and mechanical wounding were assayed in our plant growth model. The effect of abscisic acid (ABA), the most studied stress-responsive phytohormone which mediates stomatal closure and other reponses to drought and osmotic stress (ref), was
