Non-host resistance in wheat

GFP-tagged hyphae of Magnaportha grisea growing within a leaf cell of wheat

An international collaborative project, Cereal Immunity, funded by the CGIAR Generation Challenge Program (www.generationcp.org) involves Agroplis (France), INRA (France), JIC (UK), UCD (USA), NIAS (Japan), CIMMYT (Mexico) and Embrapa (Brazil).

Through global, gene expression screens in rice and wheat, Magnaporthe grisea and Puccinia triticina interactions, candidate non-host resistance genes have been identified.

Through expression, cellular and genetic analysis (Rodrigues et al., 2004) the role of these genes is being determined.
