The influence of the fungal pathogen Mycocentrospora acerina on the proteome and polyacetylenes and 6-methoxymellein in organic and conventionally cultivated carrots (Daucus carota) during post harvest storage

► This is a study aiming to understand the effects of pathogen attack on a root vegetable system where defence related metabolites and proteome response of the plant is studied. ► This is not only the first time that a proteomic approach has been used to study the Mycocentrospora acerina - carrot interaction but is remarkably the first study of its kind on a root vegetable crop, and one of very few looking at the proteome of root tissues. ► The samples used come from a field study and follow disease development and the proteome and metabolites during post harvest storage. ► The organic carrots were grown in a rotation that is sustainable for farmers, and gives a comparable yield to conventional systems.
